According to coroner Randy Daniel, the 18-year-old likely suffered a broken rib, which subsequently punctured his heart, reports CNN. He also added that Tillman would have potentially survived the beating had he not been stomped repeatedly, according to CNN.

District Attorney David McDade said 18-year-old Emanuel Boykins, 19-year-old Horace Coleman, 18-year-old Quantez Mallory, and another teen, Tracen Lamar, were charged with murder for "stomping, kicking, and punching" Tillman to death Saturday night in Douglas County, which is west of Atlanta.

Deputies who arrived at the scene tried, but failed to resuscitate Tillman.

The four accused teens attended a house party where a fight broke out between two females and two males. One of the females apparently hit a male who refused to hit her back because she was a girl, and instead vouched to beat up the next guy who crossed his path.

Moments later Tillman walked in front of the crowd.

"He had nothing to do with anything," Maj. Tommy Wheeler of the Douglas County Sheriff's Department said of Tillman, according to CBS affiliate WGCL. "They just decided he's the one. And they killed him."
