One man was killed and another wounded Tuesday in an early morning shooting in south Fulton County.

The shooting happened shortly after 4 a.m. in the 4900 block of Rock Hill Road, a short street off Sullivan Road just west of College Park.

Fulton police Cpl. Kay Lester told the AJC that investigators believe the two men were shot while in or near a Cadillac that was found outside Triple G Manufacturing, a company that makes wooden pallets.

One of the victims was dead at the scene, Lester said.

The wounded man went to Teresa White’s nearby house to get help.

White’s 17-year-old son, Joshua Joiner, said he was playing the video game “Mercenaries 2” when the man showed up at his window.

“I didn’t hear the gunshots because I was playing a shooting game,” Joiner told the AJC.

“He came to my window, banging on the window and then the door. I could tell he was shot because there was blood on the window.”

Joiner, who then woke his mother up, said the wounded man “wasn’t talking, he was just walking back and forth. He was in shock, I suppose.”

“I didn’t know anything until he woke me up and told me to call 911, that somebody was shot,” White said.

Lester said the wounded man was taken to Grady Memorial Hospital in critical condition.

Investigators have not determined a motive for the shooting, and had no suspects, Lester said. She said detectives were interviewing a witness "that may be able to give us some more information."
