In Bell v. State, 90 S.W.3d 301 (Tex. Crim. App. 2002), the Texas Court of Criminal Appeals reviewed a claim in which the appellant sought to demonstrate the possibility of his innocence by proving that someone else's DNA was at the scene of the crime. The court determined that without more, the presence of another person's DNA at the crime scene would not constitute affirmative evidence of the appellant's innocence and that therefore, the denial of DNA testing did not violate appellant's due process rights. Id. at 306.
