In May 1998, 15 year old Kip Kinkel murdered his parents and two classmates, as well as injuring 25 others, after engaging in a shooting spree that ended up in his school's cafeteria. In the investigation it emerged that he had been taking
popular antidepressant medication Prozac since the summer of the previous year.
In December 2000, Michael McDermott went on a shooting rampage at his workplace, Edgewater Technologies, killing seven of his co-workers. During his trial, the court heard testimony that in the weeks before the shooting, McDermott had tripled the dosage
of his antidepressant medication, Prozac, from 70 milligrams per day to 210 milligrams.
In March 2005, 16 year old Jeff Weise shot and killed nine people, including five students at Red Lake Senior High School in Minnesota, before turning the gun on himself. It was later revealed he had been undergoing treatment for depression and had been on Prozac
at the time.
In September 2008, Finnish post-secondary student Matti Saari shot and killed ten other students on campus before killing himself. The official Finnish government report on the incident revealed that he had been taking an SSRI medication
at the time of the shooting.
SSRI stands for Selective Seratonin Reuptake Inhibitor, and it is a class of drugs that is often used to treat depression and anxiety. It includes Prozac, Zoloft, Celexa, Paxil and a host of other commonly prescribed antidepressants. And the perpetrators of a raft of school shootings, mass murders and other violent incidents in recent years have been taking them.
