4 shot to death at South Carolina home; authorities call incident isolated as they seek gunman

South Carolina deputies say they're looking for the person who shot and killed four people at a home outside Charleston.

Orangeburg County Sheriff Leroy Ravenel told reporters that officers were called to a home shortly before 7 a.m. Wednesday and found a man dead in the yard.

Inside, they found a dead 28-year-old woman; two dead girls, ages 14 and 17; and a boy about 8 who has been taken to a hospital for treatment.

Ravenell says investigators think the shootings were an isolated incident. He says he doesn't think the person responsible is committing other crimes in the area.

Revenell also says investigators won't rest until they arrest that person.

Ravenell says deputies are following good leads, but he wouldn't not talk about a possible motive.
