A Shreveport, La., man who spent more than 20 years in prison will be released after DNA testing showed he was not responsible for the rape of a 10-year-old girl, reports the Associated Press.
Calvin Willis was convicted to life in prison in 1982 for breaking into a house in Shreveport and raping the girl.
The case against Willis, now 44, was built on a pair of underwear found at the house. Semen matched Willis’ blood type, as did scrapings taken from beneath the victim’s fingernails.
The Innocence Project took up Willis’ case and had the evidence reexamined. The tests showed the semen on the shorts and the fingernail scrapings did not come from Willis.
Prosecutors said they will not re-try him.
