* Another invalid DNA testimony can be seen in the case of STATE OF TEXAS v. JOSIAH SUTTON. The victim was raped by two men. Semen was found in the vaginal swab and on the stain removed from the back seat where the rape occurred. The official report presented invalid DNA results. The raw data and the analyst's bench notes indicated that whereas the vaginal sample reflected a mixture of the victim's DNA and DNA from two male donors, the semen stain on the car seat suggested it came from one man only and that the lone male could not be Sutton. Although Sutton was excluded as the source of the car seat semen stain, that conclusion was not mentioned in the official report nor in the analyst's testimony at trial.

If the back seat stain was considered in conjunction with the vaginal swab data, Sutton could probably have been ruled out as one of the rapists.
