Matt Hansen, Former Missouri Teacher, Accused Of Videotaping 80 Boys Undressing (VIDEO)

Matt Hansen, a 38-year-old teacher for the Fort Zumwalt School District in O'Fallon, Mo., has been charged with felony possession of child pornography after a local cyber crimes unit found he allegedly videotaped 80 male students undressing, WFMY-TV reports.

After threatening to kill himself by jumping off a cell phone tower in Iowa, Hansen was placed on administrative leave by the district, committed to a mental health facility and eventually moved to the Lincoln County Jail.

According to KSDK-TV, the students were unaware they were being taped while getting into showers while participating in the district's outdoor education program.

Authorities are now working to notify parents once the involved students have been identified.

St. Charles County Sheriff's Lt. Chris Mateja, told the St. Louis Post-Dispatch there has been no evidence to suggest Hansen inappropriately touched students or that he shared the footage with anyone.

Hansen is currently being held on a $50,000 cash-only bail.
