Gloria June Palmer, 44, vanished after an evening out with family in St. Joseph, Missouri. On June 29, 1989, the family spent the night celebrating a son’s 21st birthday and visited several local bars. At about 2:00 a.m. on June 30, Gloria was driving her Mazda truck; her sons followed and last saw her turn onto Interstate 29 southbound and then onto Interstate 229. That was the last confirmed sighting.

Her truck was later found parked and secured inside the garage of her home. Investigators reported no signs of forced entry or a struggle at the residence. At the time she disappeared Gloria was described as a white female, brown hair, brown eyes, 5 feet 4 inches, about 104 pounds, with a mole on her neck and a scar on one calf. She was wearing a pink striped top, pink pants, white open-toed flat shoes, and distinctive gold rings.

The case remains an active missing person investigation with few physical leads and no definitive explanation for what happened that night. Anyone who knew Gloria, was in St. Joseph on June 29–30, 1989, or has information is asked to come forward.
