Michael Plumadore is charged with killing Aliahna Lemmon.
He said he placed her remains inside several trash bags before putting them into his freezer. Plumadore also said that he placed other pieces of Lemmon's body in freezer bags before disposing of them in a dumpster at a nearby business.
Plumadore appeared in court Tuesday morning. He has been placed on a 72-hour hold. A pretrial hearing has been scheduled for Dec. 30 at 9 a.m. No bond has been set.
The girl and her two sisters had stayed with Plumadore for about a week while their mother was ill.
Lemmon was reported missing from the Northway mobile home park on the north side of Fort Wayne Friday.
Plumadore originally told police he last saw Lemmon sleeping in his home early Friday morning. He said he noticed she was missing a short time later and assumed she went back home to her mother.
Because of a lack of communication, Lemmon was not reported missing until Friday night.
