Pauline Klumpp, 51, disappeared from Port Arthur, Texas, on July 2, 1988, after going to check on a rental property in Port Acres. Witnesses reported her air conditioning was not working and that Roy Melanson, a man known for fixing air conditioners, offered to help. Klumpp and Melanson left together and she was never seen alive again. Her truck was found abandoned the following day in a grocery store parking lot a few miles away.

Law enforcement, including the Texas Rangers, conducted an extensive investigation and interviewed hundreds of people but never recovered Klumpp’s body. Investigators strongly suspected Melanson — a lifelong criminal recently released from the Texas prison system who was later serving a sentence for a Colorado murder — but lacked the physical evidence to file murder charges in this case. Sgt. Scott Gaspard of the Port Arthur Police Department later renewed efforts to locate Klumpp’s remains.

Anyone with information about Melanson’s movements or activities in southeast Texas around July 1988 is asked to come forward.
