Death
Rayner was killed following an altercation with a bouncer, Steven Barry Johnson, at a nightclub in Bradford, in November 1994. Johnson was charged with manslaughter but, when the case came to court on 18 November 1995, the judge decided that there was not enough evidence to charge him with manslaughter and, having already pleaded guilty to a charge of common assault, Johnson was instead put on probation and ordered to complete 100 hours of community service.
Memorial fund
The Dave Rayner Fund was set up in his memory on 12 January 1995, to help riders make a career from racing on the continent. A plaque and seat in his memory were unveiled at Gargrave, North Yorkshire on 9 July the same year. The first Rayners Ride around the Yorkshire Dales was held on 10 September and the first Dave Rayner dinner was held at Norfolk Gardens, Bradford on 4 November. Guests at the dinner were the comedian Tony Capstick, journalist John Morgan and Keith Audas. This dinner has become an annual event with guests such as Miguel Indurain, Bradley Wiggins, Mark Cavendish, and Eddy Merckx attending. David Millar became the first beneficiary of the fund. He went on to turn professional with Cofidis. More recent beneficiaries who have joined the professional peloton include Adam Yates and Dan McLay.
