After speaking with witnesses, they found that two SUVs were seen leaving the area shortly after the shooting. On Sept. 8, a witness to the shooting spoke to officers. The witness, identified by police as a woman, said that she was with Edwards that evening. The two went to a home on North Leland Avenue when a man, known to her as "Boosie" approached the vehicle. "Boosie," who was later identified by police as Mason, reportedly demanded money that was owed to him by Edwards. During the altercation, the woman exited the truck and walked toward the house on North Leland Avenue. The documents said that she heard something drop during the altercation. When the witnessed turned to see what it was, she reportedly saw "Boosie" pick up a large silver handgun and shoot Edwards three times when he was sitting in the green truck.
