BOISE -- A former teacher at a Meridian middle school has been sentenced to 15 months in prison for possessing obscene cartoons depicting child sexual abuse.

Federal prosecutors say 33-year-old Steven Kutzner was sentenced Tuesday by U.S. District Judge Edward J. Lodge. Kutzner will also be on supervised release for three years and will have to participate in sex offender treatment.

Prosecutors say investigators found 70 cartoon images of youthful animated characters -- including characters from the TV show, The Simpsons -- engaged in sexually explicit conduct.

The investigation began in December 2008 after German Federal Police discovered evidence that Kutzner's IP address offered a child pornography file for download.

Kutzner resigned as a teacher at Lake Hazel Middle School after the search warrant was served.
