DUMAS, Texas (AP) - A Texan convicted of rape must serve life in prison in a case where dog feces on his shirt matched DNA from the victim's pet.
Prosecutors presented DNA evidence from the rape, plus dog DNA found on the shirt of Rufus Sito Nanez III.
Nanez was convicted in a 2007 attack on a 27-year-old Dumas woman.
Authorities tested fecal matter his shirt, fecal matter from her yard -- where the two struggled -- and saliva from her dog.
A prosecutor says cells from the walls of colons can attach to waste material.
Jurors on Wednesday found Nanez guilty of burglary of a habitation with intent to commit a felony, plus two counts of aggravated sexual assault.
Nanez, who claimed innocence, will serve three life prison terms concurrently.
