Two people were killed and one was injured in a shooting at a North Carolina home, authorities said.

The suspected shooter was also found dead in the home at 352 Brooks Road in Prospect Hill, a town about 28 miles north of Durham, just before 8 a.m. Wednesday, authorities said.

Deputies with the Caswell County Sheriff’s Office found “multiple” people who had been shot in what they described as a “mass shooting.”

Sheriff Tony Durden said during a Wednesday press conference afternoon that three people, including the suspected shooter, were all found dead within the home with gunshot wounds. All four people were adult members of the same family. The names of the victim or the suspect have not been released.

One of the victims was transported to Duke University Hospital with a gunshot wound. Their condition was not immediately known.

Officials have not commented on whether the shooting was a domestic violence incident, but said that it was confined to the home and there is no ongoing threat to the public. A motive for the shooting was not disclosed.

“SBI Crime scene investigators are on the scene processing evidence and conducting interviews,” North Carolina SBI said. “There is NO THREAT to the general public, and the event is contained to the above address.”

The Caswell County Sheriff’s Office is working to notify the victims’ next of kin, the agency noted in a Facebook post.

The sheriff’s office is the lead agency on the case. They are receiving assistance from the SBI, the North Carolina State Highway Patrol, the Prospect Hill Fire Department, Caswell County 911 and the Person County Sheriff’s Office.

“Additional information will be released as it becomes available through press releases and the SBI and Caswell County Sheriff’s Office social media platforms,” SBI said.
