U.S. Army Captain Lynn Armstrong Reister was 30 years old and six months pregnant when she was stabbed to death in her El Paso home in May 2001. Her husband Sergeant Roger Reister, 27, and their 4-year-old son Triston discovered her body in the master bedroom. Lynn Reister’s 25-year-old brother-in-law Rodney Reister confessed to the murder and said Roger asked him to do it. According to prosecutors, Roger had an affair with 20-year-old April Lamphere (who had his child) and he was afraid he would be punished by the Army for adultery. He was also concerned that his wife Lynn would get custody of their son during a divorce.
According to Rodney, Roger intended to pay him for the murder with part of the $250,000 Roger expected to collect from Lynn’s insurance policy. Both Reister men were convicted and sentenced to life in prison. Dateline NBC will air its investigative report on the Reister murder on March 11 at 10pm.
