Wednesday morning, Prescott Police responded to a three vehicle rear-end collision on Highway-69 just. Lt. Corey Kasun says it was determined that westbound traffic was slowed as a deer attempted to cross the roadway. As traffic slowed, Honda driven by a 49-year old Prescott man, failed to slow and struck the rear of an Acura being operated by a 21-year old Prescott Valley female. The force of the impact caused the Acura to spin into the median as Honda continued west and struck the rear of a truck before coming to rest. Kasun says the driver of the first vehicle sustained serious but non-life threatening injuries and was flown to a Phoenix area hospital. The driver of the second car was transported to YRMC with the third uninjured. The incident is still under investigation to determine if impairment was a factor.
