John Columbo was last seen near his home at 161 Lakeshore Road in Lake Ronkonkoma, New York, on Tuesday, December 4, 1979, at about 1:00 p.m. He was 47, a six feet tall Caucasian man weighing about 200 pounds, with brown eyes, black partially bald hair, and a mustache and beard. He had two tattoos on his arms, one reading Mom and a U.S. Navy anchor, and reportedly had only $20 when he vanished.

The Suffolk County Police Department opened an investigation, but few public details are available and the trail has grown cold. Decades have passed without definitive answers, and the case remains open. If anyone remembers John, his movements that day, or any detail that might help explain what happened, authorities would like to hear from you.
