Douglasville investigators said the three people found dead inside a Lithia Springs apartment last week died of an apparent double murder-suicide.

Officers responded to the Crestmark Apartments about 1:30 p.m. Friday after receiving a call about shots fired, Douglasville police spokesman Maj. J.R. Davidson said.

When police arrived at the complex off Crestmark Boulevard near Thornton Road, they discovered  the bodies of three people.

Investigators identified them as 26-year-old Marshaun Russell, 29-year-old Asia Lawrence and 24-year-old Taj Luster.

“Based on crime scene evidence, it is believed this incident is a murder-suicide,” Davidson said. “Detectives are still working to determine what led up to the shooting.”

Authorities have not said which of the three people was responsible for the shooting, and an incident report won’t be made available until the investigation is complete.
