Spree killers are probably the most notorious and infamous of all multiple murderers, yet these criminals repel and fascinate us more than any other. It is difficult to understand why these perpetrators committed mass murder, since many were killed by the police at the end of their sprees and are therefore unanswerable to their crimes. Those who survived are usually certified insane – famously when Brenda Spencer, who had killed two and wounded nine, was asked why she had done it, she simply replied: ‘I don’t like Monday.’ Spree Killers provides the horribly fascinating – sometimes enigmatic and inexplicable – and terrifyingly gripping stories of 45 spree killers, from the first recorded incident in 1913 through to the most recent high school and shopping mall slaughters.
