South Carolina police are combing the Charleston area after coming upon a grisly scene that included four dead individuals — two adults and two teenagers, as well as a wounded child.

They were found at a house in Holy Hill, a small town 60 miles northwest of Charleston after getting a call early Wednesday morning, according to a Reuters report.

The found the body of one man in the yard as well as that of a woman and two female teens inside the house. Authorities also found an 8-year-old boy who was wounded and taken to the hospital in an unknown condition.

Police later found a car that had been seen at the home numerous times burned out about 15 miles away.

It’s unclear if the victims are related, but the female victims have been identified: 14-year-old Tamara Perry, 17-year-old Shamekia sanders, and 28-year-old Krystal Hutto.

Orangeburg County Sheriff Leroy Ravenell would not provide any detail on any known leads in finding the killer, saying only that they were “actively” pursuing some good leads and that they would “not rest” until they arrest the person responsible.

Authorities think it’s an isolated incident and therefore don’t think the person is still committing crimes, according to an NBC News report.

The three female victims were apparently found in two separate bedrooms that were in the home.

The boy was airlifted to a hospital in Charleston.

The car that was later found burned up and believed to be connected to the killer was a green 1990s Mercedes.
