New leads in Gwinnett quadruple shooting

GWINNETT COUNTY, Ga. — For the first time police are showing Channel 2 Action News some of the evidence they say was used in the "ambush style" quadruple shooting that left a mother, her 12-year-old son and another person dead.

Investigators are pleading for public help to catch the killer.

On Tuesday, Gwinnett County investigators showed Channel 2's Kerry Kavanaugh photographs of the assault rifle used when violence erupted at the Snellville home on Anderson Livesy Lane Sept. 15.

They are still searching for the alleged gunman, Robert Bell. He's been on the run ever since.

"He was at home basically waiting on them to show up. So they were pretty much ambushed when they got home," said Gwinnett Cpl. Deon Washington.

Deon says Bell was waiting for his new roommates Angelina Benton, her 12-year-old son Justin McDonald, Benton's 19-year-old godson and her 24-year-old boyfriend. The four were returning home from a road trip they took in Bell's SUV.

Police say Angelina Benton was shot four times when she collapsed in the yard of a neighbor who called 911. Her boyfriend was shot twice in the leg. He is the only one who survived.

According to investigators, Bell's first two victims were 12-year-old Joseph and the 19-year-old, shot almost as soon as they walked through the door.

"The weapons were found in the rear portion of the vehicle. We're assuming that his intentions were to leave," Washington said.

But Bell couldn't find the keys. So, instead he ran.

As police continue to search for Bell, they continue trying to pinpoint a motive. They say Benton had opened up her home to Bell and his wife just two weeks before the shooting.

They say Robert Bell could be in metro Atlanta, South Georgia in the Albany-area or even as far north as Chicago, Ill.
