BOXHOLM, Iowa (AP) -

A memorial service has been scheduled for a 15-year-old Iowa girl who was kidnapped and remained missing for more than two weeks before her body was discovered in a river.

A public service for Kathlynn Shepard is set for 1 p.m. Thursday at the Southeast Webster-Grand Middle School gymnasium in Boxholm. She was a ninth grade student at the school district about 60 miles north of Des Moines.

Authorities say Kathlynn and a younger friend were coerced into a pickup on May 20 in Dayton by registered sex offender Michael Klunder. He hanged himself after the younger girl escaped. It remained unclear for more than two weeks what had happened to Kathlynn.

Her body was found June 7 in the Des Moines River near Boone.
