I. INTRODUCTION

Defendant Neki Gibbs (“Defendant”) faces charges for Murder First Degree,!
and Criminal Mischief? related to two separate shooting incidents. He files this
Motion in Limine under Superior Court Criminal Rule 16(a)(1)(E) and D.R.E 702
and 703 and challenges the admissibility of the State’s ballistic evidence that seeks
to connect both incidents.3 The Court finds that the State has met its burden in
showing by a preponderance of the evidence that the expert testimony is admissible.
Although Defendant’s Motion in Limine is denied, the Court agrees to place

limitations on the opinions offered by the ballistic evidence expert.
Ul. FACTUAL AND PROCEDURAL HISTORY‘

On January 30, 2018, the Newark Police Department received a complaint for
a shots fired in the area of 100 South Chapel Street (“Newark Incident”)? On
February 5, 2018, the Wilmington Police Department responded to a home at 2230

Lamotte Street in Wilmington, Delaware and discovered the bodies of two victims

casings, three spent projectiles and four live rounds of 9mm ammunitions were
recovered from the scene of the Wilmington Incident. On September 10, 2019,
Defendant was indicted for Murder First Degree as to the Wilmington Incident,’ and
Criminal Mischief as to the Newark Incident.’

On November 24, 2018, the State submitted its initial discovery regarding its
intended ballistic expert.'! On March 18, 2019, the State submitted a letter
indicating that it was going to “call a firearms and tool mark examiner to testify as

an expert[.]”!? In May 2019, the State sent documents related to ballistics found at

Evidence, this letter is to inform you that the State intends to call a Firearm and Tool mark
Examiner to testify as an expert in the area of ballistic and firearm comparison. In summary the
expert will testify that the shell casings recovered . . . in connection with [the Newark and
Wilmington] incident[s] ... were fired from the same weapon. The State will provide the identity

June 27, 2019, the State submitted an email indicating that a “NIBIN hit is the same

based upon sufficient facts or data, (2) the testimony is the product of reliable
principles and methods, and (3) the witness has applied the principles and methods
reliably to the facts of the case.”*! The party introducing expert testimony must
“demonstrate by a preponderance of the evidence that their opinions are reliable.””

In determining “whether an expert has a reliable basis in the knowledge and
experience of the relevant discipline,””’ this Court applies the Daubert standard.
If the Court finds that expert testimony satisfies Rule 702 as interpreted under
Daubert, “cross-examination, presentation of contrary evidence, and careful
instruction on the burden of proof are the traditional and appropriate means of

attacking . . . admissible evidence.””°

operation exist; and (4) whether the theory or technique enjoys acceptance within a relevant

IV. DISCUSSION

Defendant argues that a NIBIN hit is not an expert report within the meaning of
relevant evidentiary rules and has not been peer reviewed nor supplemented with
provision of error rates.” The State maintains that NIBIN hits are “the product of a

27 stemming from a “manual[]

manual examination conducted by the State’s expert,
[comparison] by the expert . . . using the identical methodology as any other
comparison ....”°® The State further emphasizes that such methodology “is the only
method used by the Firearms and Tool Mark examiners at the Delaware State Police
Forensic Firearms Services Unit.””?

In State v. Phillips,*® the Superior Court considered this issue and found the

methodology of the Association of Firearm Toolmark Examiners (“AFTE”)?!

reliable under Daubert.** In making this finding, the Court also discussed the use of

review and publication factor under Daubert[;]”*? (3) “the AFTE theory satisfies the known or
potential rate of error factor under Daubert{;]"? (4) “the AFTE theory satisfies the existence and

in McNally v. State,** our Supreme Court concluded that it could not “find plain error
[in the admission of expert testimony] because [the expert] did explain his principles
and methodology and applied those principles and methods to the facts.”*> Here, the
State proffers that its expert will do the same.

The Court finds that where the State’s expert testimony is based on methodology
previously held reliable under Daubert, the State has demonstrated by a
preponderance of the evidence that the proposed expert testimony is reliable.*®
Following similar considerations under McNally*” and Phillips,** the State will have
the opportunity to introduce evidence that suggests a nexus between both shootings.
Defendant may challenge the evidence through cross-examination.

Although admissible, the State concedes that its expert should not testify to being

 

33 Id. at *2 (“The NIBIN system is a computer-based imaging system that assigns an algorithm to
each image it sees based on a topographical view. Ballistics evidence is placed inside the system
where it takes a photograph (i.e. digital image). It assigns values to aspects of each image by
looking down at the item and producing a list of possibilities based on what it sees. The NIBIN
system then searches its database for images that the lab has already entered into the system, or
may also be sent out to different regions for comparison to their systems. Based on parameters
entered by the examiner, the system limits and sends back a list of possible matches found, if any.
Those images from the list are then evaluated on the screen to determine what items of evidence
need to be physically examined. From that list, [the expert] conducts physical examination of the
necessary items.”’).

“100% certain as to his findings.”°? Therefore, limitations are appropriate.
Defendant agrees that the expert should not testify as to the certainty of his findings
but further asks that the expert’s report delete any references to “match or
identification.’“° The State wishes to use the terms “identification” and “match.”*!
At this juncture, the Court is not precluding the expert from using words such as
“match” and “identification.” Both sides are invited to submit supplemental
materials on the issue regarding the use of the term “match” or similar terminology
but, at this stage, no authority is before this Court to support that the terms must be
precluded in the context of ballistic evidence.

Although AFTE methodology “is generally accepted among professional

9942

examiners as a reliable method of firearms and toolmark identification,”’* current

trends in case law*? suggest that courts are limiting the expert testimony in this area.

gun could have fired the recovered materials.* Based on the trend in case law,” the
Court agrees that where “the process by which a firearms examiner declares a
‘match’ remains inherently subjective,”’*° and where the State agrees that the expert
is not to testify with “100%” certainty, the State’s expert testimony will be limited,

there is a match to “the exclusion of all other firearms in the world,” or that it is a
“practical impossibility” that any other gun could have fired the recovered materials.
He may not testify within a reasonable degree of “scientific” certainty and may not

state his conclusions regarding a “match” with any degree of certainty.

This Court is satisfied at this stage that the State has met its burden regarding the
