Donald Robin was sentenced to 17 years in prison for his role in planning school shootings.

Three other charges were dropped as part of a plea agreement.  Nine years of the sentence were suspended.  Robin could serve six years.

Robin entered a guilty plea to conspiracy to commit murder.   He cried while reading an apology before Judge Christopher Lee.

Robin will also testify against fellow defendant John Schultz who is scheduled for a suppression hearing next month.  A jury trial is scheduled for June 8.
