SWAT team members who entered the house late Tuesday found the remains of four adults and two children, including the body of the man they believe called police, Greenwood County Sheriff's Office spokesman John Long said. Investigators didn't immediately release the identities or causes of death, but Long said the situation appeared to be "domestic-related."
Authorities planned a news conference for Wednesday afternoon. In the morning, yellow police tape surrounded the one-story home on a rural stretch of road south of Greenwood, a city of about 23,000 in northwestern South Carolina.
Officers first went to the home in Greenwood County after receiving a call from a man who said he was thinking about hurting himself, Long said. He said while police were on their way, one of the man's neighbors called 911 saying four children from that address had arrived at her house and told her a shot had been fired. He said the children remained at her house.
After about an hour and "several unsuccessful attempts" by officers to make contact with anyone in the home, the SWAT team entered and discovered the bodies, Long said.
The county coroner's office did not immediately respond to an email seeking comment.
