TAOS, NM – Authorities in northern New Mexico have arrested two men accused of killing and dismembering their roommate, a fellow Army veteran, and scattering his remains across several locations in Taos County.

Rainor Joiner, 23, and David Degroat, 22, are facing charges of first-degree murder and multiple violent felonies following the death of 25-year-old Matthew McLaughlin, according to county law enforcement. Investigators linked all three men through their military service, revealing they had previously served together at Fort Benning, Georgia, before moving in together in New Mexico.

The case began when McLaughlin, originally from West Virginia, was reported missing on July 31. Local authorities, assisted by search volunteers from Virginia, searched the area while opening a missing persons investigation. As their inquiry deepened, deputies learned that Joiner and Degroat were both Army deserters with active military warrants.

On August 17, detectives brought Joiner and Degroat in for questioning. During their interviews, officials say Joiner confessed to fatally shooting McLaughlin and, with Degroat’s help, dismembering his body. Joiner later directed deputies to spots along U.S. Highway 64 near Tres Piedras, where investigators reportedly recovered multiple plastic bags containing human remains. Forensic experts at the Office of the Medical Investigator are working to identify and process the remains.

Police state that Joiner showed little emotion during questioning and provided detailed information about the crime, including the weapons used. According to court records, Joiner claimed that disputes over McLaughlin’s behavior as a roommate—and allegations of drug use and unwanted visitors—preceded the killing.

Investigators believe McLaughlin was ambushed and shot on July 25, days before he was reported missing. In separate statements, officials described Joiner’s demeanor as devoid of remorse, emphasizing the disturbing nature of his admissions.

Both suspects were booked into Taos County custody without bond. A preliminary hearing and detention review is scheduled for September 2, according to online court records.

Authorities have not disclosed whether additional suspects are involved, but say the investigation remains active. Military officials confirmed that the relevant warrants for Joiner and Degroat stemmed from desertion charges.

The case has drawn attention in the Taos community and among veteran groups who say they are saddened by the tragedy involving former service members. Local authorities have asked anyone with additional information to come forward as the investigation continues.
