Police say the man called 911 saying the boy had fallen and hit his head getting out of a bathtub and had stopped breathing. Medical scans showed a severe brain injury, and doctors noted bruising on the boy's body.

Authorities say the 12-year-old girl told investigators the man forced her to perform sexual acts, then told her he'd distribute nude photos of her if she didn't perform more sexual acts, which he recorded.

The grand jury indictment against 26-year-old Titus Miller includes two counts of sexual exploitation of five children. Miller had already been charged with production of child pornography and faces state charges of child sexual assault.

A court document says the 30-year-old woman and the 14-year-old boy exchanged electronic messages of a sexual nature and that the two had kissed. The document says there was no other sexual contact.
