Robert Warren Triplett was arrested in October. The Columbus Dispatch reports that he entered his plea to the federal charges on Friday. His trial on state child pornography charges has been continued until October in Lowndes County Circuit Court.
The 57-year-old Triplett was arrested after investigators found explicit photos of minor children on a computer obtained from his home, during an investigation into the disappearance of his stepdaughter Kaila Morris.
Morris, then 21, has been missing since Sept. 17, when she was last seen by Triplett, who said she left the home he shared with her mother in a vehicle with an unknown person.
