A Polk County deputy who was out on patrol Friday afternoon was approached by a man in a convenience store.

The man proceeded to tell the cop that he shot someone twice at his home across the street.

Hours later, the shooting victim died, leading to the shooter being charged with murder, authorities said. Rockmart police identified the suspect as 64-year-old Marshall Davidson Crews of Rockmart, who remains in the county jail without bond.

The incident began about 1 p.m. at DK’s Food Mart, with Crews running into the store and asking for an ambulance because he shot a man named “Q,” according to a news release by Rockmart police. Authorities identified the shooting victim as Quenton John Thomas Eutsey.

The deputy and other responding officers found the gravely injured man on a porch in the 500 block of East Elm Street, the release said. Police would later learn that the scene was Crews’ house.

Crews was detained by authorities while Eutsey was flown to Atlanta Medical Center. He was initially charged with aggravated assault and a firearm-related felony, but a murder charge was later added when Eutsey died at the hospital.

Rockmart police and GBI agents are investigating the case. No other information on the incident has been released.
