Richard Edward Duffy was 23 when he disappeared from Corrales, New Mexico, on December 18, 1970. Staying at a local commune with his girlfriend, he walked to the banks of the Rio Grande; according to the girlfriend, they had taken LSD and she later fell asleep. When she awoke, Richard was gone and has not been seen or heard from since.

Born and raised in New Jersey in a single-parent home, he left high school to join the U.S. Marine Corps in 1965 and served in Vietnam. After his marriage ended while he was overseas, friends and family said he adopted a hippie lifestyle and used alcohol and drugs, which ultimately brought him to the Corrales commune.

At the time of his disappearance he was described as a white male, 5 feet 10 inches, about 140 pounds, brown hair and brown eyes, with a beard. Distinguishing features included a gap between his two upper front teeth, shrapnel scars on the backs of his hands, and tattoos reading Mom on his upper left arm and Linda on his upper right arm. The Sandoval County Sheriff’s Office has an open investigation, but what happened that day remains unclear.

If anyone knew Richard, his movements in December 1970, or has information that could help his family, please come forward.
