ST. PAUL, Minn. (AP) _ Federal prosecutors have charged a former Bemidji
assistant principal with child pornography and trying to entice a minor.

The U.S. Attorney's office says 34-year-old Brandon Mark Bjerknes of Bemidji
appeared in federal court Wednesday.

Bjerknes served as assistant principal of Bemidji Middle School for the past
three years until he resigned in April. The complaint alleges Bjerknes posed as
a teenage boy and used social media profiles on Facebook and Snapchat with
``decoy photographs'' to contact girls and boys in middle and high school. Using
the alias profiles, Bjerknes allegedly directed the victims to send him sexually
explicit photographs and also engaged in sexually explicit conversations.

Authorities say Bjerknes contacted more than 50 victims, and there may be more
victims.
