US Army Veteran Believes His Roommate Is A KILLER

from FilmRise True Crime · host FilmRise True Crime

He came home to heal. He never expected the man sleeping in the next room would become his executioner.In this episode, I bring you the true crime story of a US Army veteran who believed his roommate was plotting to kill him — and was proven horrifyingly right. In Tres Piedras, New Mexico, 25-year-old Matthew McLaughlin, an Army veteran who had served at Fort Benning, moved into a home with two men from his former unit. What he didn't know was that Rainor Joiner and David Degroat had been planning his murder for weeks [citation:2]. Joiner admitted to fatally shooting McLaughlin, then dismembering his body with Degroat's help and disposing of the remains in plastic bags along US Highway 64 [citation:2]. McLaughlin's mother later revealed: "All I want to say is, I found out that they had planned this for weeks. I'll never see my son again" [citation:2]. This is a deep dive into betrayal, paranoia, and the terrifying truth that sometimes your gut instinct is right. Turn down the lights, put on your headphones, and press play — because the man he trusted was already a killer.
