Hundreds Mourn Teen Beaten to Death at Party Atlanta's Bobby Tillman didn't know his attackers By Newser Editors and Wire Services Posted Nov 13, 2010 2:00 PM CST 6 comments Comments A portrait of Bobby Tillman, the 18-year-old who was stomped to death, is surrounded by classmates and friends during a vigil Tuesday, Nov. 9, 2010, in Douglasville, Ga. (David Goldman) (Newser) – Cory Green stood over his nephew's coffin and asked the hundreds of mourners gathered to touch one another and repeat after him. "If I am not a part of the solution, then I am part of the problem," Green said, the audience reciting his words. "Because I am my brother's keeper." Family members and friends remembered Green's nephew Bobby Tillman today as a smiling, happy peacemaker and vowed not to let the 18-year-old's death be in vain. Tillman died last Sunday after a random attack at a house party. Investigators say he was stomped, kicked, and punched to death. About 200 people gathered to remember Tillman at Siloam Church International in College Park, south of Atlanta. Police say Tillman, who did not know his attackers, became a target after a fight broke out among people at a party in the Atlanta suburb of Douglasville. Investigators say the fight started when a woman hit a man. The man said he would not hit the woman back but vowed to hit the next man who walked by. Four men have been charged.
