What happened

On 22 September 1976, a mass shooting and hostage crisis occurred on Boundary Street in Spring Hill, a suburb of Brisbane, Queensland, Australia. At around 12:30 p.m. local time, 36-year-old labourer William Robert Wilson, armed with a .22-calibre rifle and 500 rounds of ammunition, began shooting at people on a car park ramp. Wilson had been diagnosed with schizophrenia and was reportedly upset after being rejected for membership by a model plane club.

Wilson first shot and wounded 28-year-old Donald Galloway and 25-year-old Virginia Hollidge. He then proceeded down the street and encountered 17-year-old Monica Schleuss, whom he shot in the head, killing her. Crossing Boundary Street, Wilson opened fire into a milk bar, fatally shooting 18-year-old Marianne Kalatzis and wounding 17-year-old Mavis Saunders. He then went to a neighbouring barber shop, where he fired at least four shots, wounding 48-year-old Quinto Alberto. Wilson subsequently fled to a house in Kelvin Grove, forced his way inside, and took five student teachers — four women and one man — hostage.

The police response to the attack was initially disorganized. Officer training was interrupted, and a vehicle carrying weapons crashed in Jindalee while responding to the scene. Once police arrived, they surrounded the Kelvin Grove house, with some officers wearing bulletproof vests and others arming themselves with rifles and shotguns. Negotiations with Wilson continued for about two hours. At 3:30 p.m., one hostage escaped by telling Wilson she needed to use the restroom before instead running down the stairway. Around 4:00 p.m., after Wilson threatened to kill the remaining hostages and was seen holding the gun to his victims, police decided to storm the house. During the entry, gunfire was exchanged between Wilson and police. Constable John O'Gorman knocked Wilson down and took him into custody at around 4:15 p.m.

On 23 September, Wilson, then 36, appeared in court charged with two counts of murder, four counts of attempted murder, unlawfully causing fear by being armed in public, and having a rifle with intent to commit a crime. He did not enter a plea at that time, stating he had not spoken to a lawyer. A judge recommended a medical examination, and Wilson was to return to court on 1 October, at which point prosecutors advised he was receiving treatment at Wolston Park Hospital. Wilson remained in the psychiatric hospital for three years before being found mentally fit to enter a plea. At age 40, he pleaded guilty and was sentenced to life imprisonment on 23 June 1980.
