Donnie (surname unknown) is a special needs delivery man in the local areas of children who were being murdered.
History[]
He innocently gave children lollipops and rides on his bike, but when children of minority races were revealed to be the victims, Detective Tutuola was personally motivated to find the killer and eagerly found Donnie a likely suspect.
He brought him into interrogation and confronted him with his bike chain, which Fin though was the same one used to murder the kids. Donnie, scared and confused, said he never used the chain other than for his bike, and even if he didn't give kinds rides when they weren't nice to him, he never liked to hurt people. He kept saying he wanted to go home to his neighborhood in the Bronx. When another child was strangled to death while he was in custody, he was released on his own recognizance due to being cleared of suspicion. (SVU: "Anchor")
