 On the evening of 26 October 1978 , about a week after the extermination threat , George Burkitt and his 20 @-@ year @-@ old son Philip were working on Philip 's Triumph Spitfire car in front of their house . At around 7pm , annoyed by the noise they were making , Williams shot them both with a 9mm , Smith & Wesson automatic pistol . George died where he fell and Philip , wounded , ran into the house . Williams followed him , shooting him again and killing him . He then shot and killed George 's wife , Iris . The Burkitts ' 17 @-@ year @-@ old daughter was hit four times in the back and once in the thigh , but survived . Two other neighbours , a married couple who had witnessed the attack on the Burkitts , also survived being shot . The injured were treated at Birmingham General Hospital .
