On a spring afternoon in 1986, Dennis M. Diamond and a friend, Donald Peterson, left Diamond's home in Franklin Township, New Jersey. Diamond, a 34-year-old house builder, told his wife to start dinner, mentioning they would be back in about an hour and a half. The two men were reportedly heading to Philadelphia in Diamond's black 1984 Buick Regal. This would be the last time their families would see them. When neither man returned home, they were reported missing on April 25, 1986. Dennis, who was a father to four young children, left behind all of his personal belongings, including his eyeglasses which he needed for night vision.
The investigation into the disappearance of Dennis Diamond and Donald Peterson took a turn when police uncovered a meth lab in a converted chicken coop on the property where both men lived; Diamond was Peterson's landlord. Following this discovery, a warrant was issued for Peterson's arrest.
The circumstances surrounding their disappearance grew more complex as time passed. Nearly two years later, on April 11, 1988, Dennis Diamond's Buick Regal was located in the parking lot of an Acme market in Upper Darby, Pennsylvania. The vehicle's identification number had been altered, and a member of the Warlocks motorcycle club had been seen driving it. When authorities attempted to question this individual, they found he had died of a drug overdose, adding another layer of mystery to the case.
Over the years, the search for answers has yielded few results. In 1997, a tip led investigators to search a private property in Woolwich Township with the belief that the men might be buried there, but the search was unsuccessful. Foul play is suspected in their disappearances. The case is characterized by a lack of significant leads and media attention since the initial investigation. At the time of his disappearance, Dennis Diamond was described as being 5'5' and weighing 183 pounds, with strawberry blonde hair and hazel eyes. He had a scar on his left arm. The disappearance of Dennis Diamond and Donald Peterson remains an unresolved case, leaving their families with unanswered questions about what happened on that April day in 1986.Last Seen: Apr 19, 1986
