12/14/2012 – Newtown, Connecticut – Adam Lanza, 20, shot and killed 26 people, including 20 students and 6 administrators at the Sandy Hook Elementary School. Lanza also murdered his mother prior to the attack and subsequently killed himself when confronted by police. Lanza was armed with 2 handguns, a Glock 9mm and Sig Sauer 9 mm as well as a Bushmaster AR-15 rifle. Although his motivation is unclear, it has been speculated that he may have been upset with his mother about the prospect of having to go through psychological treatment.

8/1/1966 – Austin, Texas – Charles Joseph Whitman, 25, an engineering student and former marine, shot and killed 14 people at the University of Texas campus and wounded 32 others. The shooting occurred in the university’s tower where he killed 3 inside and then over the course of about an hour and a half, took sniper shots at people on the ground from the 28th floor observation deck. He was ultimately shot and killed by a police officer. Whitman had murdered his mother and wife the previous evening by stabbing them with a knife. Whitman used several high powered rifles, a sawed off shotgun and three pistols in the attack on campus. An autopsy revealed that Whitman had a fatal brain tumor and had been prescribed drugs including Dexedrine, which was in his possession at the time of the spree. While a marine, Whitman was court-martialed for gambling, usury, possession of a personal firearm on base and making threats to another marine. He was sentenced to 30 days in the brig, 90 days of hard labor and stripped of his lance corporal rank to private.
4/20/1999 – Columbine, Colorado – Eric David Harris, 18, and Dylan Bennett Klebold, 17, went on a rampage at Columbine High School, killing 12 students and one teacher using homemade bombs, along with 9mm handguns and shotguns. They also wounded 21 others. The pair ultimately committed suicide at the school. It was concluded by a group of psychologists who studied the pair that Klebold was “depressive” and Harris was a “psychopath.” Harris had a website that made a number of violent threats against students and teachers at the school that included a hit list of individuals. His website also described his general hatred of society and expressed a desire to kill those who “annoyed” him. These killings sparked an intense debate in the US over gun control laws, bullying and the effect of violent video games on young people.
7/12/1976 – Fullerton, California – Edward Charles Allaway, 37, purchased a semi-automatic .22-caliber rifle at a local Kmart and brought it to California State University Fullerton where he worked as a janitor. He shot and killed 7 people in the school’s library and wounded two others. Unlike many mass-murderers, Allaway, did not commit suicide and was not shot by police. Instead, he called police from a nearby hotel where is former wife worked and turned himself in. Allaway has a history of mental illness and was diagnosed at his trial with paranoid schizophrenia by five separate mental health professionals. Allaway’s motive appears to be that he believed pornographic movies involving his ex-wife were being shown at the school library – which turned out not to be the case. He has been incarcerated at the Atascadero State Hospital after being found not guilty by reason of insanity.
4/2/2012 – Oakland, California – One L. Goh, a 43-year-old former student at Oikos University opened fire on the campus with a .45-caliber semi automatic handgun, killing 7 people and wounding several others.

3/21/2005 – Red Lake, Minnesota – Jeffrey James Weise, 16, and member of the Native American Ojibwe tribe, killed his grandfather and his grandfather’s girlfriend on the Red Lake Indian Reservation using a .22 caliber pistol he had stashed in his bedroom. He then took his grandfather’s police issued weapons – a .40 caliber Glock 23 pistol and a Remington 870 12 gauge pump-action shotgun – and drove to Red Lake Senior high school and killed seven others, including an unarmed security guard, a teacher, and five students. Weise left five others wounded and then used his grandfather’s shotgun to kill himself. After the shooting it became clear that Weise held a number of extremist views and considered himself a neo-Nazi. Weise had also tried twice to commit suicide the year before the attack and was under treatment for depression.
2/14/2008 – DeKalb, Illinois – 27 year old Steven Phillip Kamierczak, an alum of Northern Illinois University, returned to his former campus and entered the lecture hall in Cole Hall armed with three handguns, a knife, and a 12 gauge Remington Sportsman 48 shotgun concealed in a guitar case. The pistols he had included a 9mm Glock, a 9mm Kurz Sig Sauer P232, and a .380 Hi-Point CF380. Kamierczak proceeded to open fire on the assembled students with his shotgun, shooting a total of 25 people, of whom 5 were killed. Before police arrived on the scene Kamierczak shot himself, dying on the spot. Kamierczak was considered an exemplary student when he was enrolled at the university, and most considered him a caring individual who showed no prior signs of aggression. However, it is apparent that Kamierczak did a great deal of research in prior school shootings, particularly the Virginia Tech Massacre, and it is believed he adopted Cho’s MO in a copy-cat like attack.

2/12/2010 – Hunstville, Alabama – Amy Bishop, a biology professor at the University of Alabama, attended a regular faculty meeting for members of the biology department before pulling out a 9mm handgun and firing on those nearest to her, execution style. Bishop killed three professors and wounded three others. Bishop had a history of violent outbursts – the most notable incident was when she shot and killed her brother using a shotgun in 1986. The killing was ruled an accident thanks in part to the testimony given by Bishop’s mother. It is believed that the motivation for Bishop’s rampage at the University of Alabama was the fact that in the spring of 2009 she was denied tenure, and expected not to have her contract renewed after March of 2010. Bishop appealed the decision to the University’s administration, but her appeal was denied.

He had also reportedly displayed aggressive behavior and stress prior to the incident.
