Stacy McCall was 18 when she vanished from Springfield, Missouri, after celebrating her high school graduation in early June 1992. On the night of June 6–7 she and her friend Suzanne Suzie Streeter went with Suzie to her mother Sherrill Levitt’s home at 1717 East Delmar Street; the three women were last seen about 2:15 a.m. Friends became concerned the next morning when the girls didn’t show up to go to a water park and found the house unlocked with the television still on and purses, money, clothing, cars, and keys left behind.

Sherrill had last been heard from around 11:15 p.m. the previous night; the family dog was inside and anxious. The only oddities reported were a broken porch light globe and an answering‑machine message that was erased before police could hear it. Investigators from local police and the FBI have followed thousands of leads but no confirmed resolution has been announced.

If anyone knew Stacy’s routines, who she celebrated with that night, or has memories of East Delmar Street around June 6–7, 1992, please share what might help this investigation.
