ROCKMART, Ga. – Authorities in Georgia are on the lookout for a gunman they say killed four people and wounded a man in a pair of shootings.

The Georgia Bureau of Investigation tweeted early Friday that 27-year-old Daylon Delon Gamble is armed and dangerous and wanted on four charges of murder for the shootings Thursday night in Rockmart, about 45 miles northwest of Atlanta.

A GBI news release said 48-year-old Helen Rose Mitchell and 19-year-old Jaequnn Davis died at one home, and 24-year-old Arkeyla Perry and 26-year-old Dadrian Cummings died at another home several blocks away.

The GBI says 24-year-old Peerless Brown was injured at the home where Mitchell and Davis were killed. He was flown to an Atlanta hospital. His condition was unknown.

"They were targeted, but I don't know why. I have no idea why," Rockmart Police Chief Keith Sorrells told WAGA-TV.

WXIA-TV reported investigators believe the incident was related to drugs.

State police say Gamble fled in a stolen truck that has since been recovered.

Authorities initially said six people had been shot but later corrected that information.
