Houston arrived on campus armed with a
12-gauge pump-action shotgun and a
sawed-off .22 caliber rifle around 2:40 p.m. on May 1. As he entered the school, he fatally shot teacher Robert Brens, his
civics teacher during his senior year. He shot and killed Judy Davis, a 17-year-old student in Brens' classroom. Houston then walked through the hallway outside the classroom and fatally shot student Jason Edward White in the chest. Further on, Houston pointed his shotgun at another student, Angela Welch. Still, before he could fire his weapon, another student, 16-year-old Beamon Aton Hill, pushed her to safety, taking a single fatal bullet to the side of his head. The gunfire injured ten others. Houston then entered a classroom with about 25 to 30 students inside. According to reports, Houston would send student Andrew Parks to retrieve more hostages, threatening that if he did not come back, he would kill another student and eventually held over 80 students hostage. He engaged in an eight-hour standoff with police before surrendering to authorities. ==Aftermath==
