A 15-year-old boy and two men were killed in at least three shootings in separate areas of Atlanta on Saturday, police said.

The shooting that left the teenager dead happened at the Dunbar Neighborhood Center along Windsor Street around 3:30 p.m., a news release said. When officers arrived at the location just south of downtown, they found Kelvice Roberson Jr. with a fatal gunshot wound. He was pronounced dead at Grady Memorial Hospital.

A man had also been shot at the recreation center and was taken to Grady, where he survived his injuries, police said.

“Preliminary investigation indicates that the incident was the result of a gun transaction gone wrong involving acquaintances,” the news release said.

Authorities did not release information on a suspect or say why they were at Dunbar.

Earlier in the day Tay’vea Edwards, 28, was shot to death in the 100 block of Pine Street shortly before 2 a.m., police said. The shooting site sits near Renaissance Park and a Budgetel hotel. Police did not provide any details on a suspect or say what led up to the shooting.

Around 10 p.m., a third fatal shooting took place in the 20 block of William Holmes Borders Sr. Drive near the Martin Luther King Jr. National Historic Park. Officers found Mark Richards Jr., 49, suffering from a gunshot wound. He was pronounced dead at the scene.

Authorities are continuing to investigate the circumstances surrounding the three shootings.
