A Lawrence man died Saturday evening after crashing his motorcycle on Interstate 470 in Topeka.

John Williamson, 59, died after he lost control of his 2009 Harley Davidson and crashed about 5:45 p.m., according to the Kansas Turnpike Authority accident report. The accident occurred at milepost 178, which is one mile east of the South Topeka exit of the Kansas Turnpike.

Two other motorcycle riders were involved in a chain-reaction crash. Vernon Riddle, 43, Topeka, was traveling behind Williamson when Williamson crashed. Riddle braked to try to avoid Williamson, lost control of his 2005 Harley Davidson motorcycle and crashed. Traveling behind Riddle was Dustin Casto, 34, Burlingame, who lost control of his 2001 Harley Davidson motorcycle, went into a ditch and crashed.

Riddle was transported to a hospital for injuries and Casto had possible injuries but was not taken to a hospital.

A Highway Patrol trooper reported that Williamson was wearing a helmet and died at the scene, according to the Topeka Capital-Journal. The Highway Patrol also reported that seven motorcycles were traveling together to Lawrence at the time of the wreck.
