- The victims include two adults and two children
- A fifth victim, a boy, was injured, sheriff says
- Authorities believe the shooting was an isolated incident
A boy, about 8 years old, was injured, Sheriff Leroy Ravenell told reporters. The child's condition was not immediately clear.
Ravenell said that authorities believe the shooting was an isolated event and that they are "following some good leads."
"We don't think that we have anybody in this area that's still out actively committing crimes," the sheriff said.
He vowed police would not rest until "we arrest the person that killed these individuals."
Three of the four people killed were found inside a home, and have been identified. They are Tamara Alexia Almeshia Perry, 14; Shamekia Tyjuana Sanders, 17; and Crystal Hutto, 28.
The fourth victim, a black adult male, was found deceased in the home's yard. All the victims suffered gunshot wounds.
Police located a vehicle believed to be connected to that home earlier Wednesday, Ravenell said. It had been burned.
The sheriff declined to answer a number of questions, citing an ongoing investigation.
"We don't want this lingering out there with the public not knowing what's going on," he said.
