The rape investigation began when the 15-year-old told her mother about the encounter and she reported it to police, authorities said.
All three suspects were arrested last week. Boulai and Gumbs each face one count of rape and one count of child sexual exploitation, police said. They remain held at the Coweta County Jail without bond, online records show.
Garrison, who is charged with one count of child sexual exploitation, has since been released on bond, authorities confirmed.
