MESA -- A 36-year-old motorcycle rider was killed after a vehicle reportedly turned in front of him near Broadway and Dobson roads Tuesday afternoon.

According to the Mesa Police Department, the driver of an Isuzu Rodeo attempted to make a left turn into a private driveway on Dobson Road shortly before 5 p.m.

Sgt. Ed Wessing said Silvia L. Guzman, 31, turned in front of a Kawasaki motorcycle driven by Dalon Marcum. Marcum was not able to stop in time and hit the passenger-side doors of the Isuzu.

Speed reportedly was not a factor in the collision. Wessing said witness statements and physical evidence at the scene indicated Marcum was traveling at a reasonable speed near the posted 45 mph limit.

Wessing said Marcum was wearing a helmet and suffered significant head injuries. He was taken to Scottsdale Osborn Hospital and pronounced dead shortly after arrival.
