A gang of around five white youths overpower a solitary black man on a London street at night. One of them drives a knife deep into him. The fatal attack is unprovoked and over in seconds.
A few witnesses come forward, but they cannot identify the gang with court-proof accuracy. There’s an added complication. The murder occurs in an area targeted by the far-right and home to a tight-knit community with a large criminal population who look dimly on those who assist the police.
The names of those believed to be responsible are whispered around the neighbourhood. At first, the police deny the crime is racially motivated, but it becomes a cause célèbre for activists to rally around and demand change.
The similarities between the murder of Kelso Cochrane on a slum street in North Kensington on 17 May 1959, and that of Stephen Lawrence near a bus stop in Eltham in southeast London 34 years later are striking.
But while the Lawrence case burns in the public's consciousness, Kelso Cochrane’s murder became an historical footnote, even though it too was a defining moment in UK race relations.
