COUNCIL BLUFFS, Iowa (AP) — A western Iowa man has pleaded guilty in a case in which police say he sexually abused six children all under the age of 12. The Council Bluffs Daily Nonpareil reports that 30-year-old Tony Cue pleaded guilty Tuesday to two counts of sexual abuse and one count of lascivious acts with a child. Cue was sentenced immediately after his plea to 15 years in prison. He must also register as a sex offender.

Prosecutors say Cue abused children he was babysitting between 2012 and this year at his home and in woods near his home. Authorities say the mother of two of the victims was told of the abuse, but did nothing to stop or report it. She’s charged with child endangerment and being an accessory. She’s set to stand trial next month.
