Connie Lynn Royce (also listed as Connie Lyn Royse and Connie Lynn Royse) was 24 when she vanished after leaving the Hayloft bar on North Gratiot Avenue in Mount Clemens, Michigan, on the night of June 1, 1990. She had driven to Sterling Heights to meet a man she had met days earlier and arrived at the Hayloft with him and his friend around 10:00 p.m. Surveillance footage shows her leaving the bar alone about an hour later, barefoot and carrying her high heels, having left her purse behind. In the tape she appears intoxicated and stumbles as she exits. Her car was later found parked at the date’s apartment and neither she nor any confirmed trace of her has been found since.

Witnesses later reported a woman resembling Connie at a payphone near the Hayloft beside a late 1970s model car, but no confirmed link to Connie was established and police were unable to retrieve payphone records. The two men she was with that night, her ex-husband and a former boyfriend were questioned and cleared; divers searched the Clinton River with no result. The case was reopened years later but remains unsolved.
