A domestic dispute between two off-duty police officers who had been romantically involved left one dead and the other injured, authorities said.

Memphis Police Officer Jeremy Kyle kicked in the door of his ex-girlfriend's house, said Steve Shular, spokesman for the Shelby County Sheriff's Department.

Officer Teresita Watson told detectives that Kyle walked into her bedroom and pointed a gun at her and another man who was with her.

The other man shot Kyle in the chest, detectives said. Kyle died at the scene.

A bullet also grazed Watson's stomach as she struggled to disarm Kyle, deputies said. She was treated and released from the hospital Sunday.

Watson's three children, ages 3, 5 and 9, were upstairs at the time of the shooting and were not harmed, deputies said.

The officers, both 27, lived together in the home until recently, authorities said. Police had been called to the house in April after the couple got into argument, and in December when Kyle requested the presence of deputies while he moved out, Shular said.

Watson had not filed a restraining order against Kyle, authorities said. The sheriff's department has turned the case over to the district attorney, Shular.

No charges have been filed against the alleged shooter, Justin Davis, 22. Davis's gun appeared to be the only one fired, Shular said.

Both were patrol officers at the same precinct, but worked under different commands, said police Sgt. Vince Higgins.

Watson has been a police officer for four years and Kyle had been an officer for three years.
