After a man was killed and a woman was injured Saturday in Fairfax County, police say they are investigating whether the domestic shooting was a "justified homicide."
Officers responded to the 7900 block of Janna Lee Avenue in Hybla Valley about 12:30 p.m., Fairfax County police said.
Police say they took a 19-year-old person of interest into custody at the scene. He alleges that he shot and killed his mother’s boyfriend in self defense because the boyfriend lunged at him with a knife during a dispute.
The 19-year-old's mother was also shot, but she is expected to survive. Police say the person of interest is cooperating with the investigation and that they recovered a knife at the scene.
The identities of the people involved were not immediately revealed.
Authorities are waiting to interview more people who were inside of the home at the time of the shooting.
The investigation is currently classified as a “death investigation into a fatal shooting,” not a homicide investigation, according to police. No charges have been filed.
