Marcelino Crisogono Serna, an 83-year-old Hispanic man, was last seen in Riverside, California on November 29, 1979. He was a regular at the Howard Johnson’s restaurant in the Tyler Mall, a few blocks from his home, and left wearing a yellow, green, and red plaid shirt, brown pants, black oxford-style shoes, and a light brown hat. He was 5 feet 2 inches tall, about 125 pounds, with gray hair and blue eyes, spoke Spanish with very little English, and customarily carried about $300 in cash.

When family returned home around 6 PM that day they found the front door locked and a partially eaten banana on the kitchen table; Serna’s glasses, Bible, suitcase, and clothing remained in his room. Searches near the restaurant turned up nothing. Two possible sightings followed: an elderly man matching his description hitchhiking near Arlington and Streeter on December 3, 1979, and a man with a cane resembling him near Van Buren on December 7, 1979. Marcelino Serna has not been heard from since; the Riverside Police Department is the investigating agency.

Did anyone in Riverside in late 1979 see him around the Tyler Mall or recall those reported sightings near Arlington and Streeter or Van Buren?
