It is believed that 17-year-old Claudia Hidic was robbing the home where she was shot at two weeks ago with two male friends and one of them shot her.
It is alleged that when Hidic, Fortenberry and Crumley arrived at the duplex home where she was murdered, they found six people inside.
Once inside, there was a shootout between someone inside the home and one of the suspects, and in the chaos, Hidic was struck by a bullet.
Crumley surrendered on Saturday and Fortenberry was already in custody for an unrelated incident
Police however said the man, who has not been identified, is not a person of interest or a suspect.
