BECKOM
v.
The STATE.
No. A07A0735.
Court of Appeals of Georgia.
June 20, 2007.
*657 Paul S. Liston, Fayetteville, for appellant.
Jamie K. Inagawa, Solicitor-General, Alisha B. Thompson, Assistant Solicitor-General, for appellee.
MIKELL, Judge.
Following a jury trial, Kay Beckom was found guilty of three misdemeanors: contributing to the delinquency of a minor (Count 1), obstruction of a law enforcement officer (Count 2), and one count of maintaining a disorderly house (Count 3). She was acquitted of a second count of maintaining a disorderly house (Count 4). She now appeals the denial of her motion for new trial, enumerating errors which in essence challenge the sufficiency of the evidence. We affirm as to Count 1 and reverse as to Counts 2 and 3.
On review of the sufficiency of the evidence in a criminal case, the appellate court asks "whether, after viewing the evidence in the light most favorable to the prosecution, any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt."[1] As a reviewing court, we determine only whether the evidence to convict is sufficient; we do not weigh the evidence or judge the credibility of the witnesses. Thus, we will uphold the jury's verdict "so long as there is some competent evidence, even though contradicted, to support each element of the [s]tate's case."[2]
1. Beckom's first four enumerations of error challenge her conviction for contributing to the delinquency of a minor. We find no error.
Construed to support the jury's verdict, the pertinent evidence adduced at trial showed that on Friday, December 2, 2005, beginning at 8:30 p.m., a loud party took place at Beckom's home, lasting until at least 11:45 p.m. Present at the party were a number of juveniles, at least one of whom, 16-year-old T.M., was "very intoxicated" by 11:45 in the evening when his mother was called by police to pick him up from Beckom's house. T.M. testified at trial that his friend, Beckom's son C.B., had been planning this party for weeks and that Beckom knew of the plans and had given prior permission for the party to take place at her home. T.M. further testified that, on the date in question, he heard C.B. tell his mother once again of the plans to have a party in the basement of Beckom's home that evening; and that Beckom made no objection. T.M. also testified that the boys asked Beckom's boyfriend to purchase alcohol for C.B. and his underage friends; that Beckom was aware that the boys had asked her boyfriend to buy alcohol for them; and that the boyfriend did in fact buy alcohol for the juveniles.
According to T.M.'s testimony at trial, this party was expected to be the "party of the year"; as many as 50 high-school students showed up; and "[t]here was just a whole bunch of drinking and marijuana, and there was loud music and everybody was dancing. There was a couple of people that got into fights. Me, personally, I got in a fight. . . . Great party." The music was so loud that conversations were impossible unless conducted at a scream. At trial, Beckom admitted that she was at home the entire night, but she testified that she had denied her son permission to have a party that night because she was tired; that she locked the house and went to bed around 9:30 p.m.; and that she was asleep and slept throughout the *658 night without being aware that any party was going on.
Count 1 of the accusation charged Beckom with contributing to the delinquency of a minor
by knowingly and willfully encouraging several juveniles, all individuals under the age of seventeen (17), by providing an unsupervised location for the juveniles to gather where alcohol was both present and consumed by said juveniles, a delinquent act as set for [sic] in O.C.G.A. § 15-11-2(6), thus violating O.C.G.A. § 16-12-1.
Beckom asserts that "providing an unsupervised location for juveniles to gather" is not "a delinquent act"; that she could not be found guilty of contributing to the delinquency of a minor without evidence that she herself provided the alcoholic beverages to the juveniles; and that there was no evidence that she was aware of the underage drinking going on in her home. These arguments lack merit.
Under the statutory scheme, a person "commits the offense of contributing to the delinquency . . . of a minor when such person . . . [k]nowingly and willfully encourages, causes, abets, connives, or aids a minor in committing a delinquent act."[3] A "delinquent act" is defined to include "[a]n act designated a crime by the laws of this state."[4] It is a crime in Georgia for any person under 21 years old to "knowingly possess any alcoholic beverage."[5] Thus, if underage visitors to Beckom's home were drinking alcohol, and the record is replete with evidence that they were, those juveniles were in violation of OCGA § 3-3-23(a)(2) and so were engaging in a "delinquent act" under OCGA § 15-11-2(6)(A). If Beckom was aware of the juveniles' plans, allowed the party to occur without interfering, and turned a blind eye to the juveniles' alcohol consumption, she was contributing to the delinquency of a minor under OCGA § 16-12-1(b)(1).[6]
Moreover, the statute does not require that Beckom herself provide the alcohol consumed by the juveniles in her home. Beckom was not accused or convicted of furnishing alcoholic beverages to minors;[7] instead, she was convicted under OCGA § 16-12-1(b)(1), one element of which is that the juvenile, not Beckom, commit a "delinquent act": here, underage possession of alcohol, a violation of OCGA § 3-3-23(a)(2).
Beckom's argument that there was no evidence that Beckom knew that the teenagers were drinking alcohol in her house must also fail. In response to the question, "Did she (Beckom) know there was going to be alcohol [at the party]?" T.M. replied, "I think so, yes, ma'am." Without citing authority, Beckom argues that this testimony is not probative. We recognize that testimony that amounts to "nothing more than an impression on [the witness's] part, without any actual knowledge as to the fact, . . . is therefore without probative value."[8] Taking T.M.'s testimony as a whole, however, it is clear that his testimony was grounded in his own personal knowledge of the facts to which he testified.
Beckom also argues that the "totality of the evidence produced at trial" does not support the verdict. This argument does not provide grounds for reversal. "Resolving conflicts in the testimony of witnesses and weighing the evidence are functions for the jury,"[9] not for this Court on appeal.[10] Beckom *659 claims that her testimony established that she was not guilty; however, the jury was not required to accept her explanation of events.[11] We conclude that the evidence was sufficient for any rational trier of fact to find Beckom guilty beyond a reasonable doubt of contributing to the delinquency of a minor.[12]
2. Beckom was convicted of misdemeanor obstruction of a law enforcement officer[13] based on her refusal to respond to knocking at her front door or to calls made to her home phone, and "concealing the whereabouts of juveniles in her residence." We conclude that Beckom's conduct does not rise to the level of obstruction as a matter of law; therefore, we reverse her conviction under Count 2.
Refusal to answer knocking at one's front door, ringing of the door bell, or ringing of the phone, without more, does not constitute obstruction of the police, even if it is the police doing the knocking and ringing. The record before us reflects that, in the early hours of the day after the party, the police were searching for a juvenile, C.R., who had been reported missing by his father during the night. The police had observed C.R.'s car parked in front of Beckom's home. Corporal Ryan Youmans of the Peachtree City Police Department testified that he was dispatched to her home, where he knocked on the doors, both front and back, for about an hour, in an attempt to inquire about C.R. Eventually, upon discovering that the front door was unlocked, Youmans opened it and called out that he was a police officer looking for a missing boy. At that point, Beckom came to the door. Simultaneously, Lieutenant David E. Hill, also of the Peachtree City Police Department, telephoned Beckom's home in an attempt to get her to come to the door. When Beckom answered the phone, she told Hill that she was not at home, but at that moment she was at her door talking to Youmans; Hill could hear Youmans's voice in the background. Youmans told Beckom that he was looking for C.R., and though she at first denied any knowledge of C.R., she yelled for the boys and eventually C.R. emerged from the basement. After reuniting C.R. with his father, Youmans and another officer again knocked on the door and rang the doorbell in an attempt to talk with Beckom further; however, she did not answer the door a second time and the officers eventually left.
Youmans and Corporal Jean Paul Robichaux both acknowledged that, without a warrant, they did not have the right to enter Beckom's house without her permission.[14] If they did not have the right to enter, then it follows that Beckom had the right to refuse them entry. This Court has affirmed convictions for obstruction in cases involving flight from police officers after a lawful command to halt,[15] refusal to provide identification[16] or giving false information[17] to officers during an investigation or after being stopped for reckless driving,[18] lying to officers attempting to execute a warrant by asserting that the arrestee was not on the premises,[19] or the arrestee's slapping an officer while he was making the arrest.[20] In such cases, whether the defendant's act "hindered" the police in a particular situation was a question *660 for the factfinder.[21] No such circumstances are present in the case at bar.
Here, the only evidence of obstruction was that Beckom did not open her door to police officers fast enough. Once she came to the door, although she was verbally abusive, there was no evidence that she was hiding any of the juveniles, even though they were slow to emerge from the basement. She did not tell the officer that C.R. was not in the home; she merely denied any knowledge of the missing boy's whereabouts. The state has cited no authority, and we have found none, for the proposition that an individual's failure to answer the phone and failure to answer a knock on the door constitutes obstruction under OCGA § 16-10-24(a), where there is no evidence that the individual knew of an on-going investigation, and certainly no evidence that the individual was attempting "knowingly and willfully" to impede such an investigation. Therefore, applying the standard of Jackson v. Virginia,[22] we conclude that the evidence was insufficient to authorize a rational trier of fact to find Beckom guilty beyond a reasonable doubt of the offense of obstruction of an officer.
3. Beckom further challenges her conviction under Count 3 of the accusation for maintaining a disorderly house "to the encouragement of drinking or other misbehavior." Because we conclude that the state did not present any evidence as to an essential element of this crime,[23] we reverse.
A conviction under OCGA § 16-11-44 requires evidence of "not casual occurrences but general, customary habits of the house."[24] No such showing was made here. Although Beckom herself testified that two earlier parties had taken place at her house, these parties occurred almost a year earlier. The state did not present any evidence that, at these earlier parties, any underage drinking took place. The only gathering where there was evidence of underage drinking was the party at issue here, on December 2, 2005. Because there was no evidence of underage drinking at any earlier gatherings at Beckom's home,[25] we reverse her conviction under Count 3 for maintaining a disorderly house.
Judgment affirmed in part and reversed in part.
