Glenda Morrisseau was 19 and living in Winnipeg when she was last seen about 2:30 a.m. on July 17, 1991, on Logan Avenue after leaving the Stock Exchange Hotel and apparently looking for a ride downtown. Investigators concluded she probably entered an older-model, full-sized, dark-coloured station wagon driven by a middle-aged man; the vehicle was later described as possibly having light-yellow seat covers.

Her remains were found on August 7 among wooden beams and poles at the end of Youville Street in St. Boniface, roughly five kilometres from where she was last seen. She was partially unclothed, reportedly had her hands bound behind her back, and suffered massive blunt-force trauma to the face and head. Investigators believed she was likely killed around July 17 and may have been assaulted elsewhere and transported to the industrial site. A sexual motive was considered possible.

The middle-aged man and the dark station wagon remain key unidentified elements. The case was later reviewed by Project Devote, but no arrest, charge, trial or conviction has been publicly reported. If anyone knew Glenda, saw a dark station wagon with light-yellow seat covers in July 1991, or has information about the man seen with her, please come forward.
