OPINION
Thе trial court found the appellant, Curtis Lee Blackmon, guilty of possession of a controlled substance, namely cocaine. After finding two enhancemеnt paragraphs true, the trial court assessed punishment at 30-years confinement. We affirm.
1. Fact summary
Houston Police Officer J.D. Williams testified he was working undercover and wаs *713 assigned to make an undercover drug buy at a house before a raid team executed a search warrant. After Officer Williams completed the buy inside аnd while he was walking outside to his car, the appellant approached and asked if Williams wanted to buy a “rock.” Officer Williams understood the appеllant to mean cocaine. Officer Williams declined the appellant’s offer and attempted to leave. The appellant persisted and shоwed Officer Williams an opened matchbox that contained several loose rocks. Again Officer Williams declined and left the area.
Officer Williams then informed the raid team that he completed the buy and gave them a description of the appellant. After hearing Officer Williams’ broadcast, Officers Daniel Garza and B.L. McFadden spotted the appellant standing nearby. The two officers ran towards the appellant, as another officer approached in his patrol car.
Officer Garza testified the appellant saw the approaching patrol car and then throw something into a grassy area next to a tree. While the appellant was detained, Officer Garza directed Officer McFadden to where he had seen the object thrown. Officer McFadden found a matchbox containing six small plastic bags of rock cocaine.
The appellant testified that it was a cigarette butt he discarded as the officers approached. Testifying for the appellant, two other witnesses stated they did not see the appellant discard or throw anything аway. Although both witnesses stated they saw an officer looking around in the grassy area, neither saw an officer pick anything up.
2. Chain of custody
In points of error one and two, the appellant argues the evidence was insufficient to demonstrate that the substance shown to Officer Williams was the cocaine admitted into evidence. 1 Thus, the appellant contends the State failed to prove a proper chain of custody as predicate for the admission of the cocaine. The appellant apparently contends there is a break in the chain of custody between the time Officer Williams saw the cocaine in the appellant’s hand and the point where Officer Garza saw the appellant throw a matchbox.
The State contends Officer Williams’ testimony was offered to showed why the appellant was approached. In addition, the State argues the appellant was charged with the possession of the сocaine contained in the matchbox Officer Garza saw the appellant throw to the ground, not necessarily the same shown to Officer Williams. We agree.
If a substance is properly identified, most questions concerning care and custody go to the weight to be given the evidence, not to its admissibility, unless there is а showing that the substance was tampered with or changed.
Gallegos v. State,
Here, Officer McFadden testified that he kept custody of the recovered matchbox and its contents until it was submitted to the chemist for analysis. For this, the appellant offers nothing to show a break in the chain оf custody, nor argues the evidence was tampered with. Thus, the State established the requisite chain of custody for the cocaine’s admission.
We overrule points of error one and two.
3. Possession
In points of errоr three and four, the appellant argues the evidence was insufficient to demonstrate he was in possession *714 of the matchbox containing the cocaine. 2
In reviewing the sufficiency of the evidence, an appellate court must view the evidence in the light most favorable to the verdict to determine if any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.
Jackson v. Virginia,
A conviction cannot be sustained if the evidence leaves any rеasonable doubt as to the guilt of the accused.
Jackson,
In order to establish the unlawful possession of a controlled substance, the State is required to prove: (1) the accused exercised care, custody and control over the contraband, and (2) the accused knew the matter possessed was contraband.
Guiton v. State,
The appellant contends that because two witnesses to the arrest testified that he did not discard anything or that any officer retrieved anything from the ground, the State failed to meet the requisite burden of proof.
The trier of fact, however, considers credibility of the witnesses and may accept or reject any part or all of the testimony given by the State or the defense.
Minx v. State,
Here, Officer Garza saw the appellant throw an object into the grass. Officer Garza then directed Officer McFadden to the area. Officer McFadden found the matchbox, which was the only object located in the specified area.
Similar facts have been found sufficient to establish unlawful pоssession.
See, e.g., Noah v. State,
We find sufficient evidence for a rational trier of fact to find every element оf the crime beyond a reasonable doubt.
Butler,
We overrule points of error three and four.
4. Jury waiver
In point of error five, the appellant argues the trial court erred in accepting his jury waiver where the rеcord fails to show that he understood the full range of pun
*715
ishment. Relying on
Samudio v. State,
Both
Samudio
and
Wade
are easily distinguished. In
Samudio,
the court reversed an assault conviction because there was no evidence showing the defendant, either orally or in writing, expressly waivеd his right to a jury trial.
In
Wade,
the court reversed a conviction based on a guilty plea because the defendant was not informed of the full range punishment.
A trial judge is not rеquired to admonish a defendant on a plea of not guilty.
Williams v. State,
We overrule point of error five and affirm the judgment below.
Notes
. In point of error two, citing
Meraz
v.
State,
. Here again, the appellant raises both a legal and factual challenge to the sufficiency of the evidence.
