A shooting Wednesday at a home in North Carolina left three people dead, including the suspect, and another person injured, authorities said.

Caswell County deputies responded to a call for service just before 8 a.m. at a home on Brooks Road in Prospect Hill, the State Bureau of Investigation said in a news release.

Deputies found multiple gunshot victims. One person was taken to the hospital in an unknown condition.

The identities of the victims and suspect have not been released. Sheriff Tony Durden said at a news conference that everyone involved is an adult and belong to the same family.

Durden said there was no evidence that the family previously reached out to the sheriff’s office.

The Caswell County Sheriff’s Office and the North Carolina State Highway Patrol immediately responded to the shooting, the SBI said in a Facebook post.

SBI crime scene investigators are on scene processing evidence and conducting interviews.

The agency said there is no threat to the general public and that the shooting was contained to the home.

“This was an isolated incident and please keep the family in your prayers,” the sheriff said.
