Summary based on the NamUs case record (MP78901) and 9 other sources
In the winter of 1970, 23-year-old Richard Edward Duffy's life took a turn that would leave his family searching for answers for decades. A native of New Jersey, Richard, also known as Rich, was one of five siblings raised in a single-parent home. He made the decision to leave high school and enlist in the Marines in 1965. His time in the service included a tour in Vietnam, a period that coincided with personal upheaval as his wife left him while he was deployed. Upon his return, those close to him noticed a significant change. He embraced a "hippie" lifestyle, which involved heavy drinking and the use of drugs such as marijuana and hallucinogens. This new path eventually led him to a commune in Corrales, New Mexico, a scenic area near the Rio Grande. It was here, on December 18, 1970, that the known facts of his whereabouts come to an abrupt and unsettling end.

On that December day, Richard and his girlfriend, who were staying at the commune, decided to go for a hike to the banks of the Rio Grande. The couple reportedly ingested LSD during their outing. At some point, his girlfriend fell asleep, and when she awoke, Richard was gone. He had vanished without a trace, leaving behind no indication of where he had gone or what might have happened to him. He has not been seen or heard from since that day. At the time of his disappearance, Richard was described as a white male, standing 5'10" and weighing around 140 pounds, with brown hair and brown eyes. He had several distinguishing features, including a beard, a gap between his two upper front teeth, and shrapnel scars on the backs of his hands. He also had two tattoos: the word "MOM" on his upper left arm and the name "LINDA" on his upper right arm.

The disappearance of Richard Duffy has remained an open and perplexing case for over fifty years. The Sandoval County Sheriff's Office is the investigating agency, but the circumstances surrounding his vanishing are painfully unclear. His family has never given up hope of finding out what became of him. The case is a somber reminder of an era of social change and personal turmoil for many veterans returning from the Vietnam War. While many theories could be postulated, from an accidental drowning in the Rio Grande to a deliberate decision to start a new life, there is no evidence to support any specific scenario. The lack of any communication from Richard in all the subsequent years suggests a more tragic outcome, but without any physical evidence, his case remains an enduring mystery, a story without an ending for a family that has waited half a century for answers.
