Two males, aged 15 and 19 years old have died after having a head on collision with each other whilst riding dirt bikes.
Neither of the dirt bikes they were riding had headlights, and neither of the victims were wearing helmets when the bikes collided.
The two riders, James DeAnda, 19, and Keane Moss, 15, both knew each other although it is unsure what the riders were doing when they collided.
The incident took place on East Bevers Street, a half-mile from Arizona 92, south of Sierra Vista.
The motorcycles and two riders were discovered by passers by which were walking past the scene at around 12.45 am.
Both riders were pronounced dead at the scene.
