Funeral arrangements have been set for a Georgia star high school football player gunned down in a mall parking lot last week, and investigators are working to determine the motive for the shooting allegedly carried out by two teenagers later apprehended in South Carolina after fleeing the scene.

Elijah DeWitt, an 18-year-old wide receiver at Jefferson High School in Jefferson, Georgia, was fatally shot on Oct. 5 at approximately 8:15 p.m. in the parking lot of a Dave & Buster’s at Sugarloaf Mills Mall in Lawrenceville, Georgia.

Two days later, the Gwinnett County Police Department announced the arrests of Kemare Bryan, 18, and Chandler Richardson, 19, both from Lawrenceville, and apprehended in South Carolina.

Bryan and Richardson were taken into the custody of the Anderson County Sheriff’s Office and are expected to be extradited to Gwinnett County on Monday.

A visitation will be held at Jefferson Church from 6 to 10 p.m. on Tuesday before a funeral service is scheduled to begin at 6 p.m. on Wednesday at Jefferson High School. Players on both teams during a local high school football game held up two fingers in honor of DeWitt's number on Friday night.

WXIA-TV reported Friday about obtaining three 911 calls. In one, a woman describes the suspected gunman being dropped off in a black vehicle and crossing her vehicle’s path. She said she nearly ran into him before hearing gunshots while finishing parking. In another call, the operator instructs the manager of Dave & Buster's on how to perform CPR. "He's barely breathing," the manager said, frantically attempting to revive DeWitt. "No response, no response."

"I was at Dave & Buster's, I heard people screaming, I looked towards my right, and I see someone lay down," a male voice says in the third 911 call with a woman heard crying in the background. "I've never seen anything like this, man."
