imageTwo men shot and killed in a southeast Atlanta apartment just hours after apparently attending the city’s Black Gay Pride celebration on Sunday knew their killer, according to police.

Atlanta police investigators are still working to determine a motive for the shooting deaths of Samuel Blizzard Jr., a 21-year-old Georgia State University student from Virginia, and Calvin Streater, a 26-year-old Atlantan. The unit in the Station at Richmond Hill Apartments where a friend found the men shortly before midnight on Sunday belonged to Streater, but Blizzard was living there temporarily.

Police say the two men knew their killer or killers, according to the Atlanta Journal-Constitution.

“There was no forced entry” into the unit at the Station at Richmond Hill Apartments, according to APD homicide Lt. Paul Guerrucci.

The apartment complex is gated and a code is required to drive onto the property, but a pedestrian gate is often open, Guerrucci said.

The Atlanta Police Department confirmed that assessment to the GA Voice and told the newspaper that the police department’s LGBT liaison, Officer Patricia Powell, was informed of the double homicide and visited the crime scene.

APD’s internal operating policies dictate that its LGBT liaison is only to be informed of a potential bias crime, but an agency spokesperson says it’s too soon to tell if the perceived or actual sexual orientation of the men played a role in the shootings.

“The men were at a Black Gay Pride event at some point during the day…We do not know if their sexual orientation played a role in the shooting deaths,” [Otis] Redding said in a statement.

The killings come 10 days after Durand Robinson, who co-owned the black gay nightclub and party promoters Traxx and sponsored several Black Pride events, was gunned down and killed on a southwest Atlanta street.
