An eighth person has died in an attack on a Brunswick mobile home, police said. Glynn County Police Chief Matt Doering identified the victim as 19-year-old Michael Toler.
He was one of two people critically injured in the attack. A ninth victim is hospitalized.
Seven bodies were found Saturday.
The man who reported the gruesome slayings faces charges of lying to police and tampering with evidence, and authorities said they haven't ruled him out as a suspect in the killings.
Doering also announced a $25,000 reward for information in the case.
Guy Heinze Jr., 22, was arrested late Saturday and also faces charges of illegal possession of prescription drugs and marijuana, Doering said.
