WAUKESHA, WI (WTAQ) - A state appeals court agreed Wednesday that a man deserves a new trial, after he was convicted of killing a Sauk County teenager and hanging her naked body from a tree a quarter-century ago.

The Second District Court of Appeals in Waukesha said there’s enough new evidence to cast doubt on Terry Vollbrecht’s conviction.

Vollbrecht, who’s now 50, was freed on bond a year-and-a-half ago after a circuit judge ordered a new trial. He was convicted of killing 18-year-old Angela Hackl and hanging her body west of Sauk City in 1987.

Vollbrecht has proclaimed his innocence for years, and the Wisconsin Innocence Project at UW-Madison has been working for over 10 years to free him. The UW group dug up evidence which suggested that it was Kim Brown who actually murdered Hackl.

Brown is serving a life prison term for a killing in Oxford, about six weeks after Hackl was slain.

The Innocence Project said it found evidence that the deaths were similar, plus DNA which showed semen from an unknown male on Hackl’s body and a sleeping bag.
