One man was killed and two others critically injured Thursday in a late-night shooting in a south Fulton County neighborhood, police said.

Officers responding to the 10:30 p.m. shooting in the 2500 block of Picardy Circle North found a 31-year-old man dead at the scene, Fulton County police spokeswoman Kay Lester said.

“The remaining two victims, ages 25 and 37, were both transported to Grady [Memorial Hospital], both in critical condition,” Lester said in an email.

The names of the three men have not been released.

Lester said no arrests have been made.

“Detectives are working to establish motive and possible suspects,” she said.
