COCHISE COUNTY — Three motorcyclists were killed late Friday evening after both passed a vehicle in a no-passing zone on State Route 90, the Arizona Department of Highway Safety said.

The crash occurred at 10:32 p.m. between the San Pedro House and the San Pedro River at marker 330, state investigators said.

According to Raul Garcia, a spokesman with the Arizona Department of Public Safety, a motorcyclist passed the driver of a vehicle in a no-passing zone, then slammed head-on into the driver of a sport utility vehicle.

At that point a second biker with a passenger also passed the first vehicle, but that biker lost control of his motorcycle and he and his passenger were ejected from the motorcycle, Garcia said.

The driver of a second SUV then crashed into the back of the first SUV that had been hit head-on by the motorcyclist, Garcia said.

The occupants inside the SUVs were taken to local hospitals with injuries that are not life-threatening, Garcia said.

The wreck shut down the highway for several hours until early Saturday morning, said Cochise County Sheriff's officials who assisted with the crash.

It’s unknown whether drugs or alcohol were a factor in the accident.

The crash remains under investigation and no identities were released because next of kin had not been notified, Garcia said.
