Michelle Theer

Former Air Force Reservist Michelle Theer was indicted in 2002 for first-degree murder and conspiracy to commit first-degree murder in the death of her husband Air Force Captain Marty Theer on December 17, 2000. Theer was accused of killing her husband with her lover, Army Special Forces soldier John Diamond. In August 2001, John Diamond was found guilty by a military jury of first degree murder and was sentenced to life in prison without the possibility of parole. Around the date of the 2002 indictment, Michelle, who had moved to New Orleans since the murder, left Louisiana to “start a new life.” Michelle moved to Florida where she rented an apartment and had plastic surgery performed under an assumed name.

The police located and arrested Michelle Theer in August 2002 and her trial concluded on December 3, 2004. The jury returned verdicts of guilty of first-degree murder by aiding and abetting and of conspiracy to commit first-degree murder. The motive for the homicide was an early attempt to collect Marty’s $500,000 Servicemen’s Group Life Insurance policy. The prosecutor ascertained Michelle manipulated John Diamond into murdering her husband. Diamond was accused of shooting Marty multiple times execution style as he ascended a stairwell at Michelle’s place of employment in Fayetteville, North Carolina. The civilian trial court sentenced Michelle Theer to life in prison without the possibility of parole.
