TUCSON, Ariz. (13 News) - A 15-year-old boy was killed in a crash involving a vehicle and dirt bike near 29th Street and Harrison Road in Tucson on Sunday, March 19.

According to the Tucson Police Department, Kenneth Shane Decker died at St. Joseph’s Hospital, where he was taken after the crash.

Police say Decker, who did not have a driver’s license, was driving a motorcycle north on South Cathy Avenue and filed to stop at a stop sign at the intersection of East Deer Trail. He collided with a GMC Sierra that was traveling east.

The driver of the GMC immediately stopped and cooperated with the investigation. An officer from the Impaired Driver Enforcement Unit determined that the GMC driver was not impaired by alcohol or drugs at the time of the crash.

No citations or charges have been issued at this point, police said, but the investigation is ongoing.

Police said excessive speed and failure to stop for a stop sign by Decker are the major contributing factors of the collision.
