The suspect is already in custody after being arrested Friday night on unrelated aggravated assault charges, according to the sheriff’s office. McDougal, a friend of Audrii’s father, lived in a trailer on the family’s property and sometimes took the girl to catch her school bus in the neighborhood, according to Lyons. Investigators located Audrii’s remains using cell phone records, video analysis and information from McDougal, Lyons said. In 2007, he was convicted of enticing a child in Brazoria County, Texas. Amid the anxiety and uncertainty of Audrii’s disappearance, her mother said she now understands the pain of the parents of missing children who she had only ever heard about on the news.
