Angeline Sweet, a 26-year-old Native American woman, was found murdered on April 12, 1987, in a park area near Franklin and Bloomington Avenues in Minneapolis. Authorities reported she had been severely beaten, sexually assaulted, and died of asphyxiation. Her slaying was the second in a series of murders of women between July 1986 and April 1987 that raised concern the attacks were the work of a serial killer.

Investigators later charged a drifter named Billy Glaze; he was convicted in 1989 of the murders of Sweet, Kathleen Bullman and Angela Green and sentenced to three life terms. Glaze maintained his innocence. Years afterward, DNA testing arranged with the Innocence Project of Minnesota excluded Glaze and matched a different man, a convicted rapist, whose DNA was found at two murder scenes, including on a cigarette butt near Sweet’s body. Hennepin County prosecutors continued to stand by the original conviction.

Did anyone who knew Angeline or who was in that area in April 1987 see or hear anything that could shed light on her last movements?
