A judge sentenced a former church youth group leader to 15 years probation on top of the 10-year prison term he already is serving on charges he sexually assaulted a young girl in December 2000.

David Schuetz, 56, of Wausau entered an Alford plea to one count of first-degree sexual assault of a child.

Schuetz was convicted last summer on similar charges from 1993 and sentenced to 10 years in prison and 15 years probation.

In both cases, court documents said Schuetz gained the trust of the young girls and either exposed himself or sexually touched them. Court documents also say Schuetz admitted to molesting young girls since he was a teenager.
