More than half of the nation's schools reported incidents of crime for the 1996-97 school year, according to a new report by the National Center for Education Statistics.
May 1, 1992: Eric Houston, 20, killed four people and wounded 10 in an armed siege at his former high school in Olivehurst, California. Prosecutors said the attack was in retribution for a failing grade. Houston was convicted and was given a death sentence.
January 18, 1993: Scott Pennington, 17, walked into Deanna McDavid's seventh-period English class at East Carter High School in Grayson, Kentucky, and shot her in the head. He then shot janitor Marvin Hicks in the abdomen. Pennington was sentenced to life without parole for 25 years.
February 2, 1996: A 14-year-old student turned an assault rifle on his algebra class, killing two classmates and a teacher, in the central Washington city of Moses Lake. Barry Loukaitis was sentenced to two mandatory life terms for the attack at Frontier Junior High School.
February 19, 1997: A 16-year-old student opens fire with a shotgun in a common area at the Bethel, Alaska, high school. Killed are school principal Ron Edwards and classmate Josh Palacious. Two other students are wounded. Authorities later accuse two other students of knowing the shootings would take place. Evan Ramsey was sentenced to two 99-year terms earlier this year.
October 1, 1997: A 16-year-old outcast in Pearl, Mississippi, is accused of killing his mother, then going to school and shooting nine students. Two of them died, including the boy's ex-girlfriend. Authorities later accuse six friends of conspiracy, saying the suspects were part of a group that dabbled in satanism.
December 1, 1997: A youth opens fire on a student prayer circle in a hallway at Heath High School in West Paducah, Kentucky. Three students are killed and five others wounded. A 14-year-old student, described as emotionally immature, is arrested.

May 19, 1998: A high school senior shot and killed another student in the school parking lot at Lincoln County High School, three days before they were to graduate. Jacob Davis, 18, confronted Nick Creson, 18, apparently because they had argued about a girl. After the shooting, Davis reportedly put the gun on the ground, sat down next to it and put his head in his hands.
May 21, 1998: A male student who had been expelled from an Oregon high school opened fire with a rifle in the school cafeteria, killing at least one student. About 25 other students were reported wounded or injured in the incident at Thurston High School in Springfield. Earlier, two adults were shot to death at the student's home, police said.
