John Stickney, a troubled youth and ex-boyfriend of WSU student Lisa Clark, detonated a bomb on the fourth floor of Streit-Perham Hall, killing himself and wounding two policemen. Stickney, a high school dropout, was employed by Industrial Rock Products as a powder man. He drove from his home in Mercer Island to attempt a reconciliation with Clark. Stickney twice attempted to talk with Clark at her dorm room and then detonated the bomb after a failed attempt to force entry.
