Eileen Maryann Gillis, 71, vanished from her Florahome, Florida, home on February 25, 1994. She was last seen leaving her residence on Tanner Road around 11:30 a.m. for her daily walk. At the time she was described as 5 feet 4 inches, about 170 pounds, with brown hair and brown eyes.

Gillis had Alzheimer’s disease, a heart condition, and early-stage Parkinson’s, and a history of wandering. She also had a missing gallbladder scar, a fractured right ankle, and was wearing jewelry including a yellow-gold wedding band and rings with clear stones. Despite extensive searches, no trace of her was found. Authorities have classified her as endangered missing and say foul play could be involved, though no concrete evidence has been released.

Anyone who knew Eileen, saw her in Florahome on February 25, 1994, or has information that could help investigators is asked to contact the Putnam County Sheriff’s Office.
