A Crawford County Circuit Court judge has bound a principal over for trial on charges he caused injuries to a 14-year-old student.  The hearing for Bluff View Intermediate School Principal Aaron Amundson was held Thursday afternoon with a large gallery observing.  He is charged with abuse-recklessly causing harm.  Amundson applied a chemical used to remove gum to a student’s hand, then scrubbed it in an effort to remove a profanity last March.  The chemical burned the boy’s skin.  The educator’s arraignment has been scheduled for June 12th at 3:30 P-M.
