Authorities say the teenage brother of a U.S. Air Force airman who was shot and killed in his home by a Florida sheriff’s deputy in May was shot to death this week near Atlanta.

The teenage brother of a U.S. Air Force airman who was shot and killed in his home by a Florida sheriff’s deputy in May has been killed in a shooting in the Atlanta area, authorities said.

Senior Airman Roger Fortson’s 16-year-old brother, Andre Fortson, was killed this week in DeKalb County, near Atlanta’s east side, civil rights attorney Ben Crump said in a statement.

“The Fortson family is battling the loss of yet another young member of their family,” Crump said. “This has been an incredibly challenging time for them with the loss of Roger. Losing the life of yet another young family member — a mere child — has been an absolute devastation.”

Andre Fortson was found shot to death in the breezeway of an apartment complex on Tuesday, authorities said. Two groups of people had been shooting at each other for unknown reasons, DeKalb County police told WSB-TV. A 20-year-old suspect was arrested on aggravated assault charges and booked into the DeKalb County Jail, the station reported.
