Sampson County Sheriff Jimmy Thornton said the caller knows the homeowner, the Associated Press reported.

"It's gonna be a long and thorough process," Pope told WRAL News.

Victim ages range from 30s to 80s

The victims are four males and one female of various racial and ethnic identities, including Black, Hispanic and white, police said. Their ages range from 30s to 80s.

Officials are working to identify the individuals, and as of Thursday morning their connection to one another is unknown.

"Anytime you have a murder in it of itself, it is a shock to the conscience, but when you have five victims…" Pope told WRAL at the scene. "This is not normal for this community. It's not normal for any community. It should shock the conscience."

The release stated that their cause of death appears to be related to the gunshot wounds, however final cause of death will be determined by the medical examiner.
