BAYTOWN, Texas -

A Baytown man is behind bars after police said he sexually assaulted a 7-year-old girl.

Investigators said Dennis Stantford, 50, had sexually assaulted the girl at his home since 2010. The girl told police Stantford would touch her in her room, bathroom, and his home office.

In a sad twist, investigators said the girl had been placed in Stantford's home by CPS after investigators said she was sexually abused in Midland by her mom's boyfriend. Stantford is the boyfriend's father, officials said. No word on why CPS officials chose to move the girl to the home of her accused molester's father.

Stantford has been charged with sexual assault of a child under 14.
