Appellant, Jimmy Lee Vaughn, appeals his conviction for tampering with evidence. Tex. Pen. Code Ann. § 37.09(a)(1) (Vernon Supp. 2000). After finding appellant guilty, the jury assessed punishment at eight years confinement in the Texas Department of Criminal Justice — Institutional Division. Raising two points of error, appellant contends that the State's proof at trial was neither legally nor factually sufficient to sustain his conviction. We affirm.
Around this time, the female Wilke had earlier seen near appellant and the other man began to look into the open doorway of the room. Keeping his eye on appellant, Wilke stepped outside of the room and briefly scanned the area. Appellant then slammed the door behind Wilke and headed to the bathroom, with Wilke in *Page 903 close pursuit. Seconds later, both men were inside the bathroom when appellant pulled down a curtain rod containing a small clear bag of what Wilke recognized as crack cocaine rocks. After appellant refused to obey an order to get on the ground, Wilke jumped on his back and attempted to wrestle the bag from appellant. During this struggle, appellant managed to open the bag, dump its contents into the toilet, and flush it. At this point, the appellant ended his resistance and was handcuffed, with Wilke subsequently recovering a single rock of crack cocaine near the toilet. Based on this, the jury convicted appellant of tampering with unknown physical evidence. Appellant now raises two points of error, asserting legal and factual insufficiency of the evidence.
In his two issues, appellant argues that the evidence offered by the State was both legally and factually insufficient to comport with the indictment and charge given to the jury. Specifically, appellant argues that the State's evidence at trial was insufficient to prove that he destroyed an unknown object of evidence, as pleaded in the indictment and submitted in the jury charge, but instead that the testimony clearly proved that he destroyed a known object — crack cocaine. For the reasons set out below, we disagree.
Under Texas law, a person is guilty of tampering with physical evidence when: 1) knowing that an investigation is pending he, 2) alters, destroys, or conceals, 3) any record, document, or thing, 4) intending to impair its verity, legibility, or availability as evidence in the investigation. Tex. Pen. Code Ann. § 37.09(a) (Vernon Supp. 2000). To support its charge that appellant destroyed unknown evidence, the State adduced testimony from the arresting officer, Sheriff Wilke. While Wilke repeatedly stated that the destroyed substance was, in his opinion, crack cocaine, he twice conceded the possibility that the substance could have been wax, drywall, or soap. Moreover, Wilke also conceded that he never saw whether the extant piece of crack found near the toilet base fell from the bag appellant emptied in the toilet. After viewing the evidence in a light most favorable to the verdict, we conclude that the State's evidence was legally sufficient *Page 904 to prove the essential elements of tampering with physical evidence.
Employing the appropriate deference to the jury's determination, we likewise conclude that the State's evidence was factually sufficient to prove that appellant destroyed an unknown object. While the evidence destroyed by appellant could well have been cocaine, the State demonstrated that it could not positively prove this as appellant flushed it down the toilet. Under these circumstances, we hold that the jury's finding as to the unknown character of the destroyed object was no so contrary to the overwhelming weight of the evidence as to be clearly wrong and unjust. We overrule appellant's two issues and affirm the judgment of the trial court.
