Police found the remains of the 9 year old girl, Aliahna Lemmon, last night near where the crime occurred in Fort Wayne.
Allen County sheriff's deputies have arrested a neighbor and family friend.
Lemmon and her sisters were staying with Mike Plumadore for about a week while their mother was sick.
He's due to make his initial appearance in court this morning.
Lemmon's disappearance led dozens of police, firefighters and the FBI personnel to search for her on Christmas Eve.
