Lovace Renee Simmons was 22 when she vanished from Chicago in the winter of 1998. On Sunday, December 27, she attended a holiday party at her boyfriend’s residence and left that evening intending to go home. That was the last time anyone reported seeing or hearing from her.

Lovace was described as between 5 feet 6 inches and 5 feet 8 inches, about 135 to 145 pounds, with brown hair and brown eyes. She had a pea-sized birthmark on her chin and pierced ears. She didn’t show up for work the next day, an uncharacteristic absence that prompted her mother to report her missing. The Chicago Police Department classifies her case as endangered missing, but few other details have ever been released and the trail went cold quickly.

If anyone knew Lovace, saw her that night, or has information about her last movements, please share what might help investigators and the family.
