David Hull
Official State investigator / hearing witness
Utah State Bureau of Investigation agent (later described as former). Key prelim witness on campus surveillance: rooftop roll-over, prone position, drop with an object, wooded area.
Hull testified the person the state IDs as Robinson arrived ~8:30 a.m., interacted with TPUSA staff, left, returned in different clothes walking with a limp, rolled onto the roof, crawled to the edge around the shot, then jumped off with something in hand. Defense cross-examined scene handling and a bullet found elsewhere on campus that Hull said was an officer clearing a weapon.
