An Amber Alert was issued for Cunningham on Thursday, after she didn’t get on the school bus that morning and didn’t make it to school.
On Saturday, authorities announced that McDougal was being considered a person of interest in the case. He had been taken into custody on Friday for an unrelated aggravated assault charge.

On Tuesday, authorities made a heartbreaking discovery. The sheriff’s office announced that crews had located the girl’s body in the Trinity River along US-59 near Livingston.
Law enforcement officials said cellphone analysis, videos collected during the investigation, and information from McDougal himself led to the discovery. Police claim they would have found her body even without information from McDougal. According to charging documents, authorities were able to determine McDougal lied about his whereabouts on February 15 through evidence as well, which placed him at three locations of interest.
Two days before Audrii's disappearance, McDougal was pulled over, and evidence found near the river was consistent with what was inside his car.
An autopsy will determine her cause of death.
