A 27-year-old gay Atlanta man and Navy veteran is suspected of killing his mother and young sister before taking his own life in a murder-suicide in Gwinnett, just a short time after he may have gunned down a third victim in Atlanta. 

Police say Jermaine Roby – known by friends and on Facebook as JJ Roby – shot and killed his 55-year-old mother and 10-year-old sister on Friday afternoon in their Norcross home. He then is suspected of turning the gun on himself and taking his own life, according to the Gwinnett Daily Post. 

Roby apparently called his father on Friday and asked him to return to the home. That's when Vernon Skinner arrived and found the carnage, according to the AJC.

Police responded to a call from the alleged shooter's father about a person shot about 4 p.m. in a house on the 700 Block of Pebble Creek Drive.

When they arrived, they found the three family members “unresponsive, not alert, not breathing and bleeding heavily,” according to a Gwinnett County police report.

Shell casings were scattered throughout the house, officers said in the report.

The father, Vernon Skinner, told police he had left his home about 3:45 p.m. for work when he got a call from his son urging him to return home because the daughter was sick.

“Skinner returned home to find his son lying in a pool of blood,” an officer said in the police report. “Then he rushed upstairs to find his daughter the same way.”

Skinner later found his wife as well.

He was not injured, according to the report.

Gwinnett police are investigating if Roby was the shooter. Meanwhile, Atlanta police are investigating possible links between Roby and the murder of Quincy Yazie King, a 40-year-old man who was shot to death at Highland Ridge Apartments on Northside Circle, which is just off Northside Drive and Interstate 75.

King was shot about 4 p.m. on Friday and was the intended target, Atlanta police told the AJC. WSB reported that King joined Roby as he was housesitting for a friend and was under the influence of drugs before the killings.

On Monday, WSB reported that police in Atlanta and Gwinnett are investigating possible links between the killings. 

Atlanta police said they're working with detectives in Gwinnett County, and are waiting for ballistics testing on the gun, casings and bullets to confirm if he's their suspect in the murder of King.

“At this point it looks like the victim was in fact the intended target,” said Lt. Charles Hampton.

Atlanta police declined to provide additional details about King's murder or any ties to the murder-suicide in Gwinnett to Project Q Atlanta.

Police told the Gwinnett Daily Post that they weren't aware of any domestic issues at the Norcross home before the killings.

“Detectives are working to determine the sequence of events that took place before the homicides and during,” [spokesman Cpl. Deon] Washington said. “More importantly, we are investigating why a tragedy like this would happen one week before Thanksgiving.”
