John Caballero Walters, 43, was last seen April 24, 1981, in Los Angeles in the company of Carlos Limas. Both men disappeared under suspicious circumstances and investigators believe they may have met with foul play. Limas was a suspect in a homicide investigation around that time, which led authorities to theorize the two could have been murdered in connection with Limas’ alleged criminal activities.

Walters is described as a Hispanic male, 5 feet 11 inches, 165 pounds, with brown hair and brown eyes and a motorcycle tattoo on the front of his right arm. He was last seen wearing gray pants and a grayish-blue shirt. Neither man has been located and the cases remain unsolved.

Anyone with information that could help locate John Walters or Carlos Limas is asked to contact the Los Angeles County Sheriff’s Department.
