Patricia Rosansky, 17, disappeared on the morning of February 3, 1983, while walking to Battle Creek Central High School in Michigan. Two months later, on April 6, 1983, her body was found in a wooded ravine in Bedford Township near Battle Creek, partially clothed and covered with brush and identified by dental records.

The autopsy attributed her death to a brain injury from blunt force trauma with an object resembling a club. She had defensive wounds on her hands, bruises on her legs, buttocks and neck, and evidence of sexual assault; two tree limbs had been forced into her throat. In 1984 neighbors arrested 26-year-old Thomas Cress; he was convicted of first-degree felony murder in 1985 and given a life sentence based mainly on testimony from acquaintances who said he had confessed.

Years later several witnesses recanted, and convicted serial killer Michael Ronning confessed and passed a polygraph about Rosansky’s murder. Biological evidence that might have resolved the question, including semen and hair, was destroyed by the state in 1992. Does anyone have information about Patricia, her last movements, or witnesses to what happened that morning?
