BLACK BUTTE RANCH, OR -- Two kids died after their dirt bike crashed in the Deschutes National Forest Wednesday. According to the Deschutes County Sheriff's Office, deputies were dispatched to Forest Service Road 1028, south of Skylight Cave.

They learned teens were riding dirt bikes in the area. When the two 14-year-olds did not arrive at their destination, the other two - a 15-year-old boy and girl - went to find them and discovered the crash scene. The two victims appeared seriously injured. 

The 15-year-olds began life-saving efforts and a passerby took over until deputies and paramedics arrived. However, both died at the scene. 

They were wearing helmets at the time. Oregon State Police conducted a crash reconstruction. Investigators believe speed and variable terrain were factors in the crash.
