ANOKA, Minn. (AP) - A 23-year-old Burnsville man has pleaded guilty to taking two 13-year-old girls he met online to his home and sexually assaulting them.

Casey Lee Chinn pleaded guilty Wednesday in Anoka County to two counts of kidnapping and two counts of criminal sexual assault. Reports say Chinn is expected to serve about 11 years in prison.

Authorities say Chinn met the girls through a free online chat site and picked them up in Andover in late September. Police used clues from the girls' electronic devices to track the teens to the Burnsville home of Chinn's parents.

The complaint says the girls had been communicating with Chinn via text and social media apps for about a month.

Chinn had coached sports at several metro-area schools.
