Convicted rapist, cleared by D-N-A

CONROE, Texas D-N-A evidence has exonerated a man who spent 18 years in prison in Texas for sexual assault.

D-N-A testing wasn't available at Arthur Mumphrey's trial back in 1986 for the rape of a 13-year-old girl. Recent tests have shown that blood and saliva samples did not match evidence used in the conviction.

Prosecutors in Conroe have apologized to Mumphrey, who had been sentenced to 35 years in prison. Mumphrey's brother confessed to the rape this week while serving time in jail for unauthorized use of a motor vehicle. But he's unlikely to face charges in the sexual assault because the statute of limitations has expired.
