It is unclear whether Muse has had a lawyer since Friday. He is being held in Coweta County Jail, authorities said.
The victims were area owner Tommy Hawk, Evelyn’s wife – both 75 – and their 17-year-old grandson, Luke, according to officials. All were shot inside the family business, authorities said. The bodies were discovered by Coweta County Medical Examiner Richard Hawk, the couple’s son and Luke’s father, according to police. Authorities say the suspect also stole a firearm from the firing range, about 50 miles southwest of Atlanta.
