Robert David Peirce, 76, disappeared from Palm Springs, California, on December 8, 1998. He was last seen about 3:30 p.m. at the post office in the Smoke Tree Shopping Center on East Palm Canyon Drive and Sunrise Way. Peirce had Alzheimer’s disease and could become easily disoriented; his caretaker briefly turned away to mail a letter and found him gone when she looked back.

At the time he vanished he was described as a 5 feet 11 inches white male, about 175 pounds, with brown hair, brown eyes, a mustache and silver-framed prescription eyeglasses. He was last seen wearing a long-sleeved gray and brown plaid shirt and blue jeans. He had a history of wandering — on a prior occasion he was found safe 17 miles from home — and his son thought he might have been trying to get back to La Quinta, where he lived in the 1950s. An extensive search turned up no trace. The Palm Springs Police Department investigated; the case is recorded under NamUs 148458 and NCIC M202587524.

Did anyone in the area remember seeing Peirce near the Smoke Tree Shopping Center that afternoon or know of sightings afterward?
