AUBURN, Ala. >> The girlfriend of a slain Auburn football player said he was arguing with a man at a party when a third man pulled a handgun and opened fire. 

Redshirted freshman football player Jakell Lenard Mitchell, 18, died after being shot in the chest early Sunday morning at an off-campus apartment complex. It was the same apartment complex where two former football players and a third man were shot to death outside a 2012 pool party. 

Auburn police arrested 22-year-old Markale Deandra Hart of Camp Hill, Ala., on murder charges on Sunday afternoon. Hart was being held at the Lee County Jail on $150,000 bond. Police have not released a motive for the crime, but said they don’t expect additional arrests. 

Mitchell’s girlfriend, Ayanna Hughuley, 17, said Mitchell was arguing with a man in the parking lot when a third man pulled a handgun. 

"He had his gun … and was looking at Jakell," Hughuley said of the suspect. "He just started shooting. Jakell fell on the ground and he tried to get back up and run, and then he fell again. He started shooting at Jakell again while Jakell was on the ground."
