A man whose conviction for a 1991 rape was overturned has been set free.
Fifty-four-year-old Joseph Frey was being held in the Winnebago County Jail since his conviction was overturned in May.
Oshkosh Northwestern Media reports (http://oshko.sh/18c2Y85 ) he was released from jail Friday after prosecutors asked the judge to dismiss the case, saying there was insufficient evidence to retry him.
Keith Findley, co-director of the Wisconsin Innocence Project, says Frey will receive assistance from a transitional housing program in Madison.
Frey had been convicted of breaking into a UW-Oshkosh student's apartment in 1991 and sexually assaulting her at knife point.
The Innocence Project eventually took up his case, and got DNA found at the crime scene retested. The DNA was determined to match another man who has since died.
