A northeast Georgia man shot three people — killing one of them — before killing himself, police said.

Raphael Diaz de Leon, 49, killed his girlfriend's daughter, 17-year-old Alyric Fouch, shot his girlfriend and an adult bystander before shooting himself on Saturday night, according to Elberton Police Chief Mark Welsh.

Authorities said they are investigating the case as a murder-suicide.

Welsh said the incident started with an argument about Diaz de Leon's drinking.

Police said the bystander was a driver that Fouch's mother, Rhonda Cureton, had flagged down to try to escape. Diaz de Leon fired at the car, wounding both adults. Both have since been released from the hospital.
