The Mohave County sheriff’s office has identified the Dolan Springs man who was killed in a Monday motorcycle accident in his hometown. Agency spokeswoman Trish Carter said 59-year-old Marcus Alan Dansker was dead at the scene of the 5:36 a.m. crash on Pierce Ferry Road.

A 15-year-old female passenger was flown to a Las Vegas hospital for treatment of fractures and abrasions. Carter said speed was a factor of investigtive focus in trying to determine how Dansker failed to negotiate a curve before the accident.

Neither Dansker, nor the teen were wearing helmets.
