Nine people were injured in a head-on crash Saturday afternoon on Highway 97 near Sunriver. A northbound vehicle lost control near MP 154, slid sideways into the southbound lane, and collided with a southbound vehicle, sending that vehicle over a guardrail and down an embankment. The original vehicle then continued southbound, and collided with yet another vehicle. None of the victims were local. One of them was described as critically injured.
