On 22 September 1976, 36-year-old William Robert Wilson opened fire on Boundary Street in Spring Hill, a suburb of Brisbane. Armed with a .22-calibre rifle and 500 rounds of ammunition, he killed two teenage girls and wounded four other people. He had reportedly been upset after being rejected for membership by a model plane club.
Wilson then fled to a house in nearby Kelvin Grove and took five student teachers hostage. After around two hours of negotiations, one hostage escaped by pretending she needed the bathroom. Police stormed the house around 4pm, exchanging gunfire with Wilson before overpowering him and freeing the remaining captives.
Wilson spent three years in Hospital before being considered fit to plead. On 23 June 1980, he pleaded guilty to two murders and four attempted murders, receiving two life sentences and concurrent ten-year prison terms.
