In Roberson v. State, 16 S.W.3d 156, 165 (Tex. Ct. App. 2000), a Texas state appellate court rejected the defendant's argument that "DNA evidence standing alone does not show that he was the person who committed the aggravated sexual assault." 16 S.W.3d at 159.
There, the defendant "could not be excluded as a donor of the sperm found on the vaginal swab," and the "likelihood that the DNA came from the African-American defendant as opposed to another random person in the African-American population was 1 in 1800." Id. at 162.
Importantly, in Roberson, the DNA evidence was the sole evidence of the defendant's guilt. See id. at 158-59.
