He put the girl's body in several trash bags and stuffed her in a freezer until nighttime came. He worked past midnight dismembering Aliahna's body with a hack saw, the affidavit, obtained by ABC News, states. He put the pieces in garbage gas and tossed them in a Dumpster of a nearby business, but kept her head, hands and feet in his freezer.

Plumadore, who had been babysitting Aliahna and her two sisters for a week because their mother was ill, initially told police that he has last seen Aliahna sleeping in his trailer on Friday but didn't alert police to her disappearance until Friday night because he believed she had gone home to her mother.

Allen County Sheriff Ken Fries said the girl's body was found after 9 p.m. Monday night.

According to the girl's relatives, Plumadore had been taking care of and living with Aliahna's grandfather, James E. Lemmon, until he died on Dec. 3, 2011, the AP reported. Plumadore was living in the grandfather's trailer at the time of Aliahna's death.

"[Plumadore] was a trusted family friend," Aliahna's stepgrandfather, David Story, told the AP.

James Lemmon was 66 when he died, and had an extensive criminal record, including convictions for child molestation in 2006 and was a registered sex offender.

Plumadore was arrested after his third interview with police, Cpl. Jeremy Tinkel told ABCNews.com.

Fries said Plumadore has a criminal record in North Carolina and Florida. Plumadore's next hearing is scheduled for Dec. 30.
