Barry Kenneth Williams (1944 – 24 December 2014), known since 1994 as Harry Street, was a British spree killer. A foundry worker who lived with his parents, he shot eight people in the English Midlands towns of West Bromwich and Nuneaton in little over an hour on 26 October 1978, killing five. Following a high-speed car chase, he was arrested and in 1979 was convicted of manslaughter on the grounds of diminished responsibility. He was detained in high-security hospitals under mental health legislation.
