A former FBI agent stabbed his estranged wife to death before police say he shot himself in Crownsville, Md. on Wednesday morning.

Officers responded to a domestic incident around 8 a.m. in the 500 block of Arundel Blvd., Anne Arundel County police said.

Upon arrival, officers found a woman outside suffering from stab wounds and a man suffering from stab wounds and an apparent self-inflicted gunshot wound. Both the man and the woman were pronounced dead at the scene.

The woman has been identified as 54-year-old Donna Fisher and the man has been identified as 52-year-old David Raynor.

Police say officers were called after Fisher asked a citizen to call 911 because she was being threatened by her recently estranged husband.
