A mother pleaded guilty last week to allowing two men to have sex with her then-9-year-old daughter.

Mary Perry was sentenced to 30 years in prison on charges of child abuse and child neglect.

She and her husband, Christopher Perry, were charged with allowing Robert Young (pictured below, far right) and Michael Halveland (pictured left of Young) to have sex with their daughter.

Halveland has also pleaded guilty and is awaiting sentencing. Young is awaiting trial.

The girl's grandmother is also charged with allowing the sexual abuse to take place. She's awaiting trial.

Christopher Perry is awaiting trial on amended charges. He is scheduled to be in court Sept. 10.
