Naperville police are investigating a weekend crash that killed a 39-year-old motorcyclist.
Denver J. Hinkle, 39, of the 1600 block of 59th Street, Downers Grove, died from injuries suffered after he crashed his red 2005 Ducati motorcycle about 5:54 p.m. Friday on Chicago Avenue, west of Naper Boulevard, police said.
Hinkle apparently sideswiped a red 2003 Ford Explorer, causing him to lose control and hit a curb on the north side of Chicago Avenue, police said.
Hinkle was transported to Edward Hospital in Naperville, where he later was pronounced dead; the Explorer driver was not injured.
Police said that "excessive speed and alcohol use by Hinkle" were contributing factors to the crash.
Police are asking anyone with more information about the crash to call the department's traffic unit at (630) 305-5285.
