A distraught wife is accused of going to the suburban Kansas City home of the mistress and shooting her three times in the face.
Shannon O'Roark Griffin, a retired training specialist at Johnson Space Center, now faces capital murder charges. Her husband, Air Force Colonel Roscoe Griffin used to be a NASA computer instructor in the 1980s.
The couple lived in the Houston area for decades. Police say they were in therapy, when the husband admitted to having an affair with a Missouri psychiatrist and brought up the possibility of a divorce.
Investigators say that prompted O'Roark Griffin to go shoot the mistress to death.
