Mary Carol Hill‑Frederick, 37, was last seen the evening of June 3, 1994, at her Seminole Heights home in Tampa, Florida. Her last known sighting was about 9:30 p.m.; afterward the house was found locked with the porch light on and her school materials left on a table. Her burgundy Pontiac Subaru station wagon remained at the residence, but her purse and a small revolver were missing.

Mary worked for the Florida Department of Health and Rehabilitative Services and had recently begun law school at Stetson University. Her husband and son were camping in Colorado when she disappeared. A co‑worker, Louis Joseph Hlava III, who had once been close to the family, was reportedly with Mary the night she vanished and is described as a person of interest; he cooperated early on but later stopped communicating with police and the family. No substantial evidence has been found to charge anyone and the case remains unsolved.

Did anyone in Seminole Heights in June 1994 see Mary’s car, her purse, or anything unusual that night?
