Don Steven McDougal was first named as a primary person of interest in the case and later a suspect in her murder.



Polk County District Attorney Shelley Sitton said McDougal is charged with capital murder of a person equal to more than 10 years old but less than 15 years old.

McDougal was already in custody on an unrelated aggravated assault with a deadly weapon charge.

According to Lyons, McDougal admitted to leaving the house with Audrii the morning she disappeared but would not tell investigators what happened next.
