U.S. rapper Slim Dunkin was Friday shot and killed at an Atlanta music studio, WSB-TV reported, citing both police and the performer's attorney.

Atlanta Police Department spokesman Maj. Keith Meadows said Dunkin, whose real name was Mario Hamilton, was shot and killed outside a music studio in the 1000 block of Memorial Drive on Friday night. He was at the studio to shoot a music video.

"Now it's my understanding prior to the video shoot, Mr. Hamilton became involved in a verbal altercation with another individual who we believe produced a handgun, discharged that weapon at least one time, striking Mr. Hamilton in the chest," Meadows said.

Dunkin's attorney Michael Mann told WSB-TV that the rapper was taken to Grady Memorial Hospital where he was pronounced dead.

Homicide detectives were on the scene late Friday conducting an investigation, Atlanta police spokesman Curtis Davenport told the Atlanta Journal-Constitution.

Music news website HipHopDX reported that Dunkin was a childhood friend of Waka Flocka Flame and appeared on Gucci Mane and Waka's "Ferrari Boyz" album released over the summer.

Another industy website, TheBoomBox, reported that the Brick Squad affiliate was to appear in the "Push Ups" video for Mane and V-Nasty when he was shot.
