Jury Throws Out Trespass Charge

A 17-year-old Pioneer High School student who was one of four persons arrested last November during a disturbance at the school has been found not guilty by a District Court jury. Mark P. Campbell of 817 Loyola Dr. was charged with trespassing in the confrontation with police and school officials outside the Pioneer building on Nov. 11. Police took Campbell into custody after former Deputy Superintendent of Schools Frederick Holliday said he suspended the teenager and then ordered Mm to leave the grounds. Campbell was arrested after he failed to leave. The six-member District Court jury heard the case in Judge S. J. Elden's court. Holliday was brought back to Ann Arbor from his present school post in Philadelphia to testify. Joseph Redmond, a Pioneer teacher and defense witness, testified he took a baseball bat away from Campbell shortly before the arrest but did not believe the teen-ager heard the suspension order from Holliday. Campbell testified he was not aware of the suspension. Frederick MacDonald of Ypsilanti was the defense lawyer and Assistant Prosecutor Thomas F. Shea appeared for the state.
