A Milton family is mourning a teen whose life was cut short while police continue their search for his killer.

“He was God's gift to me, to my family, to the people who loved him, and now he's God’s," Mary Jo Walker told Channel 2’s Mike Petchenik.

Her 19-year-old son, Chris, was shot to death Tuesday night at home after a trip to the North Point Mall area. Police said a man confronted the Georgia Perimeter College student, demanding his money. Police believe it was a random crime.

"There was a scuffle between the two. Early indication is he tried to grab something from the victim and the victim resisted," Milton Police Capt. Shawn McCarty said.

Police said there were several witnesses, including one who saw the gunman run across her lawn. Officers are still piecing together what happened before the teen arrived home.

"It's a good thing we have a lot of witnesses, but we're having to go back and piece these stories together and making sure we are getting the right pieces that fit together," McCarty said.

Milton police continued gathering evidence Wednesday from the family’s home on Silhouette Court. Meanwhile, Walker’s parents and younger brother are heartbroken.

“That person should use their conscience and come forth.  Our family is hoping for justice for Chris," Walker said.

Anyone with information is asked to call Milton police at 678-297-6300.
