A man convicted of killing a DeKalb County father during what authorities called a four-hour random shooting rampage has started serving his sentence while more charges await in Fulton County.

Mikeal Callaway, 26, was convicted by a jury on Jan. 30 of killing Nicholas Bankston as Bankston drove home from his own 24th birthday party on Feb. 22, 2018. DeKalb County Superior Court Judge LaTisha Jackson sentenced Callaway to life without parole, plus 145 years.

On Friday, Fulton County prosecutors confirmed they still intend to try Callaway for allegedly shooting and injuring two people in Atlanta during the spree.

What allegedly motivated Callaway to strike out on the bizarre spree isn’t clear.

The first shooting happened on I-20 in Atlanta, just after midnight, when Callaway, driving a silver SUV, allegedly pulled up to another driver’s car and shot him. Two hours later, a driver wrecked after taking a bullet in the neck on Fulton Street, 4 miles from the scene of the first shooting.

From there, authorities have said, Callaway ended up off Flat Shoals Road in DeKalb, where he fired into Bankston’s car. He left behind a 1-year-old daughter and a fiancée who was pregnant with another daughter, the family said. In addition to murdering Bankston, Callaway was convicted of shooting at relatives who were in Bankston’s vehicle.

As news spread of the shootings, a tipster alerted police hours later to a silver Infiniti SUV, which Callaway had apparently spray-painted in an attempt to disguise it. A Georgia state trooper spotted the SUV on Constitution Boulevard in south DeKalb.

Callaway refused to pull over initially but later stopped at a Moreland Avenue shopping center, where he was arrested.
