Army SSG John Diamond Convicted of Murder of Air Force Capt. Frank Theer; Military Court Sentenced to Life in Prison, No Parole (August 28, 2001)

Michele Theer photo

John Diamond, US Army

Army SSG John Diamond, 28, was accused of fatally shooting Air Force Capt. Frank ‘Marty’ Theer in Fayetteville, North Carolina on December 17, 2000. Capt. Theer and his wife Michelle were on their way to a Christmas party when Michelle claimed she needed to stop at her place of employment. After waiting for awhile, Capt. Theer exited his vehicle to check on Michelle. As he ascended the stairs at the office building, he was shot multiple times and died at the scene. The Fayetteville Police Department launched a homicide investigation and would learn that Michelle Theer was having an affair a married Fort Bragg Army Ranger named John Diamond. It was later theorized that psychologist and Air Force Reservist Michelle Theer was the mastermind behind the murder of her husband. She was accused of setting Capt. Theer up when she lured him to her office; she was also accused of manipulating SSG Diamond to commit the murder. The prosecutor’s theorized the motive for the homicide of Capt. Theer was the Servicemen’s Group Life Insurance money.

During the investigation, the police got a tip that a gun matching the murder weapon was in the custody of SSG Diamond which connected him to the crime. Conveniently, SSG Diamond admitted to having a gun that fit the description of the one used in the murder but he claimed his vehicle had been broken into and the gun was stolen. SSG Diamond was arrested by the US Army for having an unregistered weapon on a federal installation while they investigated his role in the murder. They would learn that despite his marriage status, he was in love with Michelle Theer and would do anything for her. The military courts charged SSG Diamond with first degree murder and on August 28, 2001, a six-member military panel at Fort Bragg found him guilty; Staff Sgt. John Diamond was sentenced to life in federal prison. Michelle Theer disappeared by the time the civilian authorities caught up with her but she was eventually located in Florida living under an assumed identity. Michelle Theer was convicted of conspiracy to commit first degree murder on December 3, 2004 and sentenced to life in prison, no parole.
