A resident found her body and called police.
In a twist to the story, Allen's good friend is missing.
Crystal Collins says her 16-year-old daughter has been missing since last week. Karensha Phelps was last seen at Allen's sister's house.
According to Collins, Allen was her daughter's role model and they'd been friends since elementary school.
Collins says Phelps has a history of running away, but always goes to a friend's home and quickly returns. She hasn't been seen or heard from since Aug. 22, and there has been no activity on any of her social media accounts.
"If something happened to Dominique, KK (Karensha) would have surfaced by now," said Collins. "We haven't had a phone call. She has everybody's number by heart. Maybe my daughter's scared because she knew something, then something happened. Or maybe something happened to her or somebody has her. We just don't know. My gut feeling is somebody has my baby or she's scared and she knows something."
Collins says her daughter answers to Kat or KK and has a lower back tattoo that says "Kat."
