Florencio Hernandez Mendoza was 91 when he was last seen on May 10, 1998, in Blythe, California. Officers say he walked away from a park at Broadway and Chanslor Way and never returned. Mendoza was reported missing after searches turned up nothing.

He was described as between 5 feet 0 inches and 5 feet 7 inches tall, weighing about 150 to 180 pounds, with gray balding hair and brown or hazel eyes. He had a hunched back, a surgical scar on his abdomen, was hard of hearing, and was thought to suffer from possible dementia. On the day he vanished he wore a blue or black baseball cap, a blue long-sleeved shirt, brown pants, black shoes, and a watch with a brown band.

Few details have emerged about his whereabouts since the disappearance and the case remains unsolved. Anyone who knew Florencio Mendoza or who has information about that day is asked to contact the Blythe Police Department.
