Authorities say speed and alcohol are likely factors in the fatal motorcycle accident late Friday night, in central Iowa’s Jasper County. The Iowa State Patrol reports a 2001 Harley Davidson motorcycle was traveling east on Highway 6 just before 11-p.m., when it failed to properly execute a curve in the road. The cycle struck a mailbox and vaulted off a driveway before crashing.

One person died at the scene, another was flown by Mercy One helicopter to Mercy Hospital in Des Moines. No names have been released.
