Patrick Francis Ross was 22 when he was last seen on March 3, 1984, at his home in San Dimas, California, near the 400 block of North Amelia Avenue. He was described as 6 feet 2 inches, about 145 pounds, with brown hair and blue eyes. Ross wore contact lenses and may have been carrying a brightly colored knapsack. His tan ten-speed bicycle with sponge rubber hand grips is also missing.

Very few details are available about what happened that day. The Los Angeles County Sheriff’s Department has investigated but reports no significant leads and classifies Ross as an endangered missing person. His DNA is on file for comparison if new evidence surfaces.

If anyone knew Patrick, his routines, or saw him or his bicycle around March 3, 1984, can you share what you remember?
