A man died late Saturday after he was found shot inside a parked car in Atlanta, one of at least four shootings police investigated within five hours overnight.

Omar Whatley, 39, died of his injuries at Grady Memorial Hospital, authorities said. According to a police report, officers found Whatley with a gunshot wound to his head, sitting in a car in the 600 block of Cascade Avenue just before 11:15 p.m.

“Preliminary investigation shows this shooting was the result of a drive-by shooting,” the report said.

Three other shootings that evening resulted in injuries. About 10:30 p.m., officers were called to the 400 block of Larkin Street to investigate another shooting and found one man with gunshot wound. He was stable when he was taken to Grady hospital.

“Witnesses stated they heard shots fired in the area but did not see what occurred,” police said. No information on a suspect was provided.

About 9:50 p.m., police were sent to the 1500 block of Martin Luther King Jr. Drive after a man was shot, authorities said. The victim was taken to Grady, where he was stable Sunday.

And on Sunday morning, about 2:40 a.m., officers investigated a shooting in the 200 block of Wellington Street. The victim told police he had been shot during a “physical altercation.” During the incident, the suspect’s weapon discharged by accident, grazing him, police said.

The suspect ran away following the flight and subsequent shooting and has not been found.

“The victim refused to cooperate during the investigation and refuse to be transported for medical attention,” police said.

All four incidents remain under investigation.
