By that point, it was 2010 and police believed they had enough witnesses to prove McGuffin had lied about his whereabouts and he was the only one with a motive.
Steinoff and 100 other people testified in front of a grand jury, hoping to convince it that there was enough evidence to indict McGuffin for homicide. Shortly after the decision was handed down, police arrested him.
The question still remains: If McGuffin did kill Leah, what was his motive?
According to police, Leah allegedly had told some of her friends that her period was late and she possibly was pregnant. He was 18 and she was 15, and police suspect that McGuffin feared statutory rape charges.
After his arrest, McGuffin's family claimed that drug dealers should be investigated for Leah's death.
Leah's mother, Cory Courtright, said she doesn't believe there will ever be closure for her, but believed her daughter deserved justice.
"I just can't stand the thought of somebody getting away with taking such a beautiful, young life. It's just wrong," she said. "Whoever did this needs to pay."
