                              Eduardo Mora-Hernandez, Appellant

                                   The State of Texas, Appellee


     FROM THE DISTRICT COURT OF TRAVIS COUNTY, 427TH JUDICIAL DISTRICT
       NO. D-1-DC-12-301539, HONORABLE JIM CORONADO, JUDGE PRESIDING



                             MEMORANDUM OPINION


                A jury convicted appellant Eduardo Mora-Hernandez of the offense of manslaughter

and assessed punishment at 20 years’ imprisonment.1 The district court rendered judgment on the

verdict. In four issues on appeal, Mora-Hernandez asserts that the district court abused its discretion

in overruling his motion to suppress (1) cell-phone records owned by his cellular-service provider

and (2) statements that Mora-Hernandez had made during an interview with police officers, and in

overruling his objections to (1) a photograph of the victim’s remains and (2) expert testimony

regarding cell-phone location technology. We will affirm the judgment of conviction.


                                          BACKGROUND

                At trial, the jury heard evidence that on August 10, 2012, skeletal remains, later

identified as belonging to Margaret Ann Robles, were discovered in a wooded area at Roy Guerrero



       1
           See Tex. Penal Code § 19.04.
Park in Austin. An autopsy was performed on the remains. The likely cause of death, according to

Travis County deputy medical examiner Leisha Wood, was blunt force trauma to the head, although

Wood acknowledged that the decomposition of the remains had made it difficult for her to determine

the exact cause of death.

               Friends and family of Robles testified that Robles had been missing since June 2012.

During the police investigation into Robles’s disappearance, officers had focused their attention on

Mora-Hernandez, Robles’s ex-boyfriend, who was reportedly the last person to have seen her alive.

Evidence implicating Mora-Hernandez in Robles’s death, which we discuss in more detail below,

included statements that Mora-Hernandez had made to police officers tending to show that he

and Robles had a volatile relationship characterized by accusations of infidelity and fights, other

statements tending to show that he had hit Robles in her head with his fist during one such fight, and

cell-phone records tending to show that, on the night that Robles had disappeared, Mora-Hernandez

had been present at the park where Robles’s remains had been found. Based on the above and other

evidence, the jury found Mora-Hernandez not guilty of the charged offense of murder but guilty

of the lesser-included offense of manslaughter. The jury assessed punishment as noted above and

the district court rendered judgment on the verdict. This appeal followed.


                                   STANDARD OF REVIEW

               We review a district court’s evidentiary rulings for abuse of discretion.2 We are to

view the record “in the light most favorable to the trial court’s determination, and the judgment will

be reversed only if it is arbitrary, unreasonable, or ‘outside the zone of reasonable disagreement.’”3

We consider the ruling in light of what was before the district court at the time the ruling was made.4

“We will sustain the lower court’s ruling if it is reasonably supported by the record and is correct on

any theory of law applicable to the case.”5

                Additionally, when reviewing rulings on motions to suppress, “[t]he appellate court

must apply a bifurcated standard of review, giving almost total deference to a trial court’s

determination of historic facts and mixed questions of law and fact that rely upon the credibility of

a witness, but applying a de novo standard of review to pure questions of law and mixed questions

that do not depend on credibility determinations.”6 “When there are no written findings explaining

the factual basis for the trial judge’s decision, we imply findings of fact that support his ruling

so long as the evidence supports those implied findings.”7 “Generally, implied findings would

be limited to the record produced at the suppression hearing.”8 “However, when the parties

                                            ANALYSIS

Suppression issues

                  Prior to trial, Mora-Hernandez had filed a motion to suppress evidence, asserting

that (1) cell-phone records owned by his cellular-service provider had been illegally obtained by the

State and (2) certain incriminating statements made by Mora-Hornandez to police officers had

been obtained in violation of his Miranda rights.10 Following a hearing, the district court denied the

motion to suppress on each ground, and it again denied the motion when Mora-Hernandez re-urged

these contentions during trial. In his first and second issues, Mora-Hernandez asserts that on each

ground, the motion to suppress should have been granted.


       Cell-phone records

                  In an attempt to ascertain Mora-Hernandez’s whereabouts on and around the

night that Robles had disappeared, the Travis County District Attorney’s Office had, by means of

a court order, obtained certain records from Mora-Hernandez’s cellular-service provider. The

records, which tended to show where Mora-Hernandez’s cell phone had been located during the time

period when Robles had disappeared, were obtained without a search warrant. In his first issue,

Mora-Hernandez asserts that the warrantless collection of those records violated his Fourth

Amendment rights.

                  The Fourth Amendment guarantees “[t]he right of the people to be secure in their

persons, houses, papers, and effects, against unreasonable searches and seizures.”11 However, for

the Fourth Amendment to be implicated, an individual must have a “reasonable” expectation of

privacy in the place or object to be searched.12 It is now well established that individuals have a

reasonable expectation of privacy in the information stored within their cell phones.13 However, the

issue in this case is whether individuals have a similar reasonable expectation of privacy in historical

cell-phone location information stored by cellular-service providers.

                  After the parties had briefed this issue, the Court of Criminal Appeals concluded that

they do not. In Ford v. State, the defendant was charged with the murder of his ex-girlfriend, and

the State’s evidence included “historical cell-tower data” from the defendant’s cellular-service

provider revealing where Ford’s cell phone had been located on the night of the murder.14 Ford

argued on appeal that the warrantless collection of this information violated his Fourth Amendment

rights.15 The Court of Criminal Appeals disagreed, observing that “the Fourth Amendment does

not prohibit the obtaining of information revealed to a third party, even if the information is revealed

on the assumption that it will be used only for a limited purpose and the confidence placed in the

       13
           See Riley v. California, 134 S. Ct. 2473, 2493 (2014) (holding that search warrant is
generally required before officers may search information stored in cell phone); State v. Granville,
423 S.W.3d 399, 417 (Tex. Crim. App. 2014) (similarly holding that suspect has reasonable
expectation of privacy “in the contents of his cell phone,” even following arrest, and that police must
obtain warrant before searching phone).

third party will not be betrayed.”16 The court explained that Ford “neither owned nor possessed

the records he sought to suppress. Rather, the cell-tower records are created by the cell-phone

companies themselves and are subject to their control. [The provider] collects and stores this

historical cell-site-location data for its own business purposes, in part to optimize service on its

network. . . . The providers control what they record and how long these records are retained.”17

Moreover, the court added, individuals should know that when they use their cell phones, their

location information is not private but is instead transmitted by cell towers to cellular-service

providers, who record and store the information.18 For these and other reasons, the court concluded

that Ford “had no legitimate expectation of privacy in records held by a third-party cell-phone

company identifying which cell-phone towers communicated with his cell phone at particular

points in the past.”19

                  We find Ford to be dispositive here. The information that was obtained by the State

in this case is the same type of information that was obtained by the State in Ford. Accordingly, we

cannot conclude that the district court abused its discretion in denying Mora-Hernandez’s motion

to suppress on the ground that Mora-Hernandez had no reasonable expectation of privacy in the cell-

phone location information sought by the State.20

                  We overrule Mora-Hernandez’s first issue.

       Custodial interrogation

                After Robles’s remains had been discovered, Austin Police Department detectives

Rogelio Sanchez and William White decided to interview Mora-Hernandez. The record reflects that

Sanchez and White conducted two interviews with Mora-Hernandez at the police station on the same

date and that at no point during either interview was Mora-Hernandez read his Miranda rights.21

Following the first interview, which Mora-Hernandez concedes was non-custodial in nature, the

detectives transported Mora-Hernandez to the park where Robles’s remains had been found and,

once there, Mora-Hernandez provided information to the detectives confirming that he had been at

the park on the night that Robles had disappeared. After the detectives returned to the station with

Mora-Hernandez, he was interviewed a second time. During this interview, Mora-Hernandez told

Sanchez that he “ha[d] to have a lawyer.” Sanchez nevertheless continued the interview, and Mora-

Hernandez eventually made statements tending to implicate himself in Robles’s death, including

statements admitting that he had hit Robles in her head with his fist and that, after she had fallen to

the ground and failed to get up, he had left her at the park alone. In his second issue, Mora-

Hernandez asserts that these statements were inadmissible because he had invoked and been denied

his Fifth Amendment right to counsel during the second interview, which he contends rose to the

level of custodial interrogation.

                “The Fifth Amendment prohibits the government from compelling a criminal suspect

to bear witness against himself.”22 “In Miranda v. Arizona, the Supreme Court crafted safeguards

to protect this ‘privilege against self-incrimination’ in the inherently coercive atmosphere of

custodial interrogations.”23 Custodial interrogation is defined as “questioning initiated by law

enforcement officers after a person has been taken into custody or otherwise deprived of his freedom

of action in any significant way.”24 “Before questioning a suspect who is in custody, police must

give that person Miranda warnings.”25 “Only if the person voluntarily and intelligently waives

his Miranda rights, including the right to have an attorney present during questioning, may his

statement be introduced into evidence against him at trial.”26 Moreover, once a suspect invokes his

Fifth Amendment right to counsel, all police questioning must cease until counsel has been provided

or the suspect initiates further communication with the police.27

                However, the Fifth Amendment right to counsel applies only when a person is

subject to custodial interrogation.28 Thus, if Mora-Hernandez was not in custody during the second

interview, then the Miranda requirements do not apply.29 “When considering ‘custody’ for Miranda

purposes, we apply a ‘reasonable person’ standard—‘[a] person is in ‘custody’ only if, under the

circumstances, a reasonable person would believe that his freedom of movement was restrained to

the degree associated with a formal arrest.’”30 “In determining whether an individual was in custody,

a court must examine all of the circumstances surrounding the interrogation, but ‘the ultimate

inquiry is simply whether there [was] a formal arrest or restraint on freedom of movement of the

degree associated with a formal arrest.’”31 The determination of custody depends on the objective

circumstances of the interrogation, not the subjective views of the person being questioned or

the subjective intent of the officer to arrest or not arrest.32 After the circumstances surrounding the

interrogation are considered, the court must determine whether, “given those circumstances, would

a reasonable person have felt he or she was not at liberty to terminate the interrogation and leave.”33

The “reasonable person” standard presupposes an innocent person.34 Moreover, the defendant bears

the burden to establish on the record “that the statements he wishes to exclude were the product of

custodial interrogation.”35

                In making its determination of whether Mora-Hernandez was in custody, the

district court considered a video recording of Mora-Hernandez’s interviews with the police; a

transcript of the interviews, translated from Spanish to English; and the testimony of Detective

Sanchez, who had conducted the interviews with Mora-Hernandez. Sanchez testified that, on the

day of the interviews, he and White went to Mora-Hernandez’s house, identified themselves as

police officers, and asked Mora-Hernandez if he would come with them to the station to answer

questions regarding Robles’s disappearance. Sanchez also testified that Mora-Hernandez was not

under arrest and that they had informed Mora-Hernandez that the interview was voluntary and that

he did not have to come with them to the station if he did not want to do so. According to Sanchez,

Mora-Hernandez agreed to answer their questions at the station, and they transported him there.

               The record reflects that the first interview with Mora-Hernandez began at

approximately 1:00 p.m. and continued until 4:37 p.m., at which time Sanchez and White left the

station with Mora-Hernandez and drove to the park where Robles’s remains had been found. They

returned to the station at approximately 6:00 p.m. and began the second interview.

               On the recording of the second interview, Sanchez and Mora-Hernandez can be seen

walking into the interview room together, with Sanchez holding bags of fast food that the detectives

had picked up on their way back from the park. Sanchez then placed some of the food on a small,

circular table in the room and asked Mora-Hernandez if he wanted a Dr. Pepper. Mora-Hernandez

told Sanchez that he wanted a Coke instead and Sanchez left the room. Mora-Hernandez, who was

not in handcuffs at any point during the interview, sat down at the table and began eating his food.

A few minutes later, Sanchez returned to the room with a Coke, gave it to Mora-Hernandez, and then

left the room again while Mora-Hernandez continued to eat. Approximately twenty minutes later,

Sanchez returned to the room, collected the fast-food trash from the table, and then left the room.

Several minutes later, Sanchez returned and the questioning began, with Sanchez seated across


                                                10
the table from Mora-Hernandez. As the interview progressed, and Mora-Hernandez began to reveal

more information, Sanchez moved his chair closer to Mora-Hernandez, and was seated between

Mora-Hernandez and the door to the room. For certain portions of the interview, Detective White

can also be seen in the interview room, mostly seated in a chair in the corner of the room, several

feet away from Sanchez. The recording reflects that when White was present in the room, he was

primarily a silent observer, although he occasionally asked Sanchez questions and directed Sanchez

to ask Mora-Hernandez particular questions.

               Sanchez and Mora-Hernandez can be heard on the audio portion of the recording

speaking to each other in Spanish. However, the recording was transcribed and subsequently

translated from Spanish to English. The transcript of the interview indicates that Sanchez told Mora-

Hernandez on multiple occasions that he was free to leave, at one point telling him, “You are not

arrested, there’s the door, leave. You want us to take you home? I’ll take you home, [and] we will

continue the investigation.” At another point during the interview, Sanchez told Mora-Hernandez,

“[Y]ou can leave whenever you want,” and Mora-Hernandez indicated that he understood. Sanchez

also testified that the door to the interview room was unlocked. Additionally, Mora-Hernandez left

the interview room on one occasion to use the bathroom, and he was alone in the interview room on

multiple occasions while Sanchez either attended to other business or left to get Mora-Hernandez

water and gum. In total, the second interview lasted approximately four hours and ended shortly

after 10:15 p.m. At the end of the interview, Sanchez told Mora-Hernandez that he was “taking

[him] home.”

               Mora-Hernandez points to several circumstances in the record to support his theory

that he was in custody during the second interview, including: (1) the total length of time that Mora-


                                                 11
Hernandez had been accompanied by the officers that day, including both interviews and the visit

to the park; (2) Sanchez positioning himself between Mora-Hernandez and the door as the second

interview progressed; (3) the size of the interview room, which Sanchez acknowledged in his

testimony was “small”; (4) the presence of two officers in the room at certain times during the

interview; and (5) certain statements by Sanchez that, according to Mora-Hernandez, suggested that

Sanchez would not “immediately honor” Mora-Hernandez’s request to leave.36 Although these facts

could support a finding that Mora-Hernandez was in custody, they do not compel or conclusively

establish such a finding, particularly when there are other facts in the record that support the

district court’s finding to the contrary. The objective circumstances that support the district court’s

finding that Mora-Hernandez was not in custody during the second interview include the following:

(1) Mora-Hernandez was told that he was not required to accompany the detectives to the station

and answer their questions; (2) during the interview, Sanchez told Mora-Hernandez on multiple

occasions that he was free to leave; (3) Mora-Hernandez was not in handcuffs or other physical

restraints at any point during the interview; (4) Mora-Hernandez seated himself when he entered the

interview room; (5) Mora-Hernandez was provided food at the beginning of the interview and water

during the interview; (5) Mora-Hernandez ate his food alone, without officers present; (6) at the

times when White was in the interview room, he was not seated at the table with Sanchez and Mora-

Hernandez but was instead seated in the corner of the room several feet away from Mora-Hernandez;

(7) the detectives were in “plain clothes” during the interview; (8) Mora-Hernandez was left alone



       36
           For example, at one point during the interview, Mora-Hernandez told Sanchez, “Well if,
if you’re going to drop me off where you picked me up, let’s go.” Sanchez replied, “You want to
leave right now? You don’t want to talk to me, this is your last chance right now.” The interview
continued.

in the interview room on multiple occasions; (9) the door was unlocked during the interview;

(10) Mora-Hernandez was allowed to leave the interview room to use the bathroom; and (11) at the

conclusion of the interview, Mora-Hernandez was not arrested but was transported home.

                Again, we are to sustain the district court’s suppression ruling if it is “reasonably

supported by the record,” and we can overturn the ruling only if it lies “outside the zone of

reasonable disagreement.”37 Based on the totality of the objective circumstances summarized above,

and viewing the evidence and all reasonable inferences therefrom in the light most favorable to the

ruling, we conclude that the record reasonably supports the district court’s determination that Mora-

Hernandez’s freedom of movement was not “restrained to the degree associated with a formal

arrest.”38 Accordingly, we cannot conclude on this record that the district court abused its discretion

in denying the motion to suppress on the ground that Mora-Hernandez failed to establish that he

was in custody so as to trigger the Miranda requirements, including the Fifth Amendment right

to counsel.39

                We overrule Mora-Hernandez’s second issue.

Evidentiary issues

                In his third issue, Mora-Hernandez asserts that the district court abused its discretion

in admitting a photograph depicting Robles’s skeletal remains, which Mora-Hernandez claims was

more prejudicial than probative.40 In his fourth issue, Mora-Hernandez asserts that the district court

abused its discretion in admitting expert testimony.41


       Photographic evidence

                During the testimony of Stacy Boatright, a crime scene specialist for the Austin Police

Department, the State offered into evidence two color photographs depicting Robles’s remains. The

first photograph depicted the remains from what Boatright described as a “somewhat far distance.”

The second photograph showed the remains at closer range, revealing their advanced state of

decomposition. Mora-Hernandez had no objection to the first photograph but objected to the second

photograph as more prejudicial than probative. The district court overruled the objection.

                “Rule 403 requires that a photograph have some probative value and that its probative

value not be substantially outweighed by its inflammatory nature.”42 “A court may consider

many factors in determining whether the probative value of photographs is substantially outweighed

by the danger of unfair prejudice. These factors include: the number of exhibits offered, their

gruesomeness, their detail, their size, whether they are in color or black-and-white, whether they are

close-up, whether the body depicted is clothed or naked, the availability of other means of proof, and

other circumstances unique to the individual case.”43 “‘Rule 403 favors the admission of relevant

evidence and carries a presumption that relevant evidence will be more probative than prejudicial.’”44

“All evidence is prejudicial to one party or the other—it is only when there is a clear disparity

between the degree of prejudice of the offered evidence and its probative value that Rule 403

is applicable.”45

                 The district court would not have abused its discretion in finding that there was no

such “clear disparity” here. Mora-Hernandez asserts that the photograph “did nothing to advance

the argument that [Mora-Hernandez] was responsible for the death of Robles.” However, the State’s

theory of the case was not merely that Mora-Hernandez was responsible for Robles’s death, but

that he had caused her death on or around the date that she had disappeared and had hid her body

where it would not be discovered. It would not be outside the zone of reasonable disagreement

for the district court to conclude that a photograph depicting Robles’s remains in an advanced

state of decomposition was probative of the timing and location of Robles’s death, which in turn

corresponds to evidence of Mora-Hernandez’s location at the time, so as to establish Mora-

Hernandez’s responsibility for her death and disappearance. Additionally, it would not be outside

the zone of reasonable disagreement for the district court to conclude that the photograph was

probative of other issues in the case, including: (1) why it was difficult for the medical examiner to

determine the exact cause of death; (2) whether Mora-Hernandez had intended to hide the body

where it could not be found; and (3) whether the physical evidence in the case was consistent or

inconsistent with the statements that Mora-Hernandez had made to the police.

                Nor would the district court have abused its discretion in finding that the probative

value of the photograph was not substantially outweighed by its inflammatory nature. The State

acknowledges in its brief that the photograph is “disturbing and gruesome.” However, “[a]

trial court does not err merely because it admits into evidence photographs which are gruesome.”46

Given the nature of this case, which involved the killing of a woman and the abandonment of her

body in a secluded area where her remains would not be found for two months, it would not be

outside the zone of reasonable disagreement for the district court to conclude that the photograph

“depict[ed] nothing more than the reality of the brutal crime committed.”47 We also observe that the

challenged photograph was the only photograph admitted into evidence that revealed the advanced

state of decomposition of the remains, which supports a finding by the district court that the evidence

was not “needlessly cumulative” of other evidence.48 On this record, we cannot conclude that the

district court abused its discretion in admitting the photograph.49

                We overrule Mora-Hernandez’s third issue.

       Expert testimony

                The State called Shelia Hargis, a crime analyst supervisor for the Austin Police

Department, to provide testimony concerning the analysis and interpretation of the cell-phone

location information that had been obtained by the State. During her testimony, the State offered

into evidence maps that Hargis had prepared to illustrate her analysis and findings in the case. Mora-

Hernandez objected on the ground that Hargis was not “qualified as an expert in this area to

draw these types of maps.” After Hargis provided additional testimony regarding her training

and experience, Mora-Hernandez maintained his objection, asserting that Hargis had failed to

demonstrate an ability “to make this type of analysis without a mathematical background.” The State

argued in response that Hargis did not need to possess a background in mathematics to discuss the

evidence that she would present. The district court overruled the objection.

                “If scientific, technical, or other specialized knowledge will assist the trier of fact to

understand the evidence or to determine a fact in issue, a witness qualified as an expert by

knowledge, skill, experience, training, or education may testify thereto in the form of an opinion

or otherwise.”50 “Thus, before admitting expert testimony under Rule 702, the trial court must be

satisfied that three conditions are met: (1) the witness qualifies as an expert by reason of [her]

knowledge, skill, experience, training, or education; (2) the subject matter of the testimony is an

appropriate one for expert testimony; and (3) admitting the expert testimony will actually assist the

fact-finder in deciding the case.”51 In this case, Mora-Hernandez challenges Hargis’s qualifications.

                  “Because the possible spectrum of education, skill, and training is so wide, a

trial court has great discretion in determining whether a witness possesses sufficient qualifications

to assist the jury as an expert on a specific topic in a particular case.”52 “‘Absent a clear abuse of that

discretion, the trial court’s decision to admit or exclude testimony will not be disturbed.’”53

                  “There is no rigid formula for determining when an expert is qualified to testify.”54

“[A]n appellate court should consider three criteria when determining whether a trial court abused

its discretion in evaluating a witness’s qualifications as an expert: (1) ‘is the field of expertise

complex?’; (2) ‘how conclusive is the expert’s opinion?’; and (3) ‘how central is the area of

expertise to the resolution of the lawsuit?’”55 “[T]he proponent must ‘establish that the expert has

‘knowledge, skill, experience, training, or education’ regarding the specific issue before the court

which would qualify the expert to give an opinion on that particular subject.’”56 “The focus, then,

is on the ‘fit’ between the subject matter at issue and the expert’s familiarity therewith, and not on

a comparison of the expert’s title or specialty with that of the defendant or a competing expert.’”57

                  Here, the subject matter at issue were maps showing where Mora-Hernandez’s cell

phone had been located at particular points in time. When asked how she was qualified “to do this

sort of mapping” and to explain her “training in this type of analysis,” Hargis testified that she had

attended “a couple of classes” on phone analysis: (1) a 16-hour course taught by a Houston Police

Department sergeant whose job is “to do the phone investigative side of phone tracking and analysis”

and whose unit “does this all the time”; and (2) a 28-hour course “taught by an intel analyst with

the Royal Canadian Mounted Police who has done extensive phone analysis.” Hargis added that she

had “somewhat associated training in Analyst’s Notebook which is actually one of the software

applications I used to do the phone time lines.” When asked to describe her process in creating

the maps, Hargis explained that she “prepare[d] the data in a form to be imported into a software

application,” in this case “Microsoft’s Streets and Trips,” and that “[w]hen you import it in, it takes

the GPS coordinates that you have on your spreadsheet and puts dots on a map.” Hargis was also

asked if “determining the azimuth [i.e., the angle or direction,] and potential radius of each potential

antenna” on a cell tower was “something the program does or is that something that you’re trained

to do.” Hargis testified, “Well, that information is in the record. So the merging of the call detail

records with the tower information is something I’ve been trained to do.” Hargis also testified that

she had performed this type of analysis “in approximately 44 cases,” including one or two cases in

which she had testified.

                Hargis further testified that as a homicide analyst, she works with “a lot of products

that help simplify the information we’re getting,” including association charts, timelines, and

“thumb analysis” showing “what towers were hit by phones during a certain time frame.” Hargis

acknowledged that she had no degree in mathematics, although she did have a degree in criminal

justice. The State also elicited the following testimony in response to Mora-Hernandez’s argument

that Hargis was unqualified by virtue of not having a background in mathematics:


                                                  19
       Q.      Ms. Hargis, in your training and experience as a police officer in doing this
               type of analysis, you’ve heard defense counsel allude to advanced math skills
               that he assumes are required to do this type of analysis. Is that true? Do you
               have to have an advanced math degree to do this type of analysis?

       A.      No, sir. I mean, I can’t explain the engineering side of how cell phones work,
               but I can, given the data that the phone company gives us, I can tell you
               where the towers are that are involved in that phone call.

       Q.      And you’re able to tell based on the information that’s given what the
               azimuth is? In other words, what direction the towers point—or the antennas
               point and then calculate 120 degrees on either side of that?

       A.      Yes. I mean, the azimuth is a column in the spreadsheet and it will say 0
               degrees or 120 degrees or something. So there’s no interpretation of that. It’s
               just that. And then the next step is to know how to read a compass and to
               know that north is 0 degrees and south is 180 degrees.

       Q.      So no cosigns—

       A.      No.

       Q.      —no advanced trigonometry or geometry is required?

       A.      No.


               In summary, in addition to her general experience as a homicide analyst, Hargis

testified that she had performed this particular type of phone analysis in approximately 44 cases,

including at least one case in which she had provided testimony on the subject matter. Additionally,

Hargis testified that she had attended two courses on the subject, one 16 and one 28 hours in length,

and that both courses were taught by police officers who were themselves, according to Hargis’s

testimony, experienced in this type of analysis. As for her lack of a background in mathematics,

Hargis testified that such a background was not necessary, and the district court would not have

abused its discretion in crediting this testimony, particularly in light of Hargis’s other testimony

tending to show that the maps were created using a software application with which she was familiar.

                                                 20
According to Hargis, the software performed the necessary mathematical calculations after she had

imported the relevant data into the application, a task that Hargis testified she was “trained to do.”

On this record, we cannot conclude that the district court clearly abused its discretion in finding that

Hargis’s qualifications were sufficient to “help the trier of fact to understand the evidence” presented

by the State.58

                  We overrule Mora-Hernandez’s fourth issue.


                                           CONCLUSION

                  We affirm the judgment of the district court.
