A former Rochester man has entered into a plea agreement in a child pornography case. 43-year-old John Crane of Pine Island went before Judge Gary Larson in Olmsted County Court on Wednesday and admitted to possessing and disseminating child porn. The charges were filed last fall after a search of his Rochester residence turned up tens of thousands of sexually explicit images of children on computers and storage devices. Crane is scheduled to be sentenced on May 15th.
