When 18 year-old Morné Harmse walked into his high school in 2008, armed with a samurai sword, he had one mission – to commit a massacre. Inspired by the Columbine high school killings, his fantasy to make people "take notice" had been brewing for over a year. By the time his sword-slashing spree had ended, a pupil was dead and three others brutally injured. Now, 14 years later, Harmse is out on controversial parole. Samurai Sword Murder finally puts together the pieces of this brutal tragedy.
