CHEMULT, OR -- Two deadly crashes tied up traffic on Highway 97 Wednesday, between La Pine and Chemult, in Klamath County.

According to State Police, 39-year-old Juan Ochoa Bravo, of Bend, was driving northbound Wednesday morning, when he lost control and slid into the path of a semi. Bravo died, along with four of his passengers, including a one-year-old child.

OSP says road conditions contributed to the crash, and several passengers were not wearing seatbelts.

That evening, a 78-year-old California man also crossed into the path of a southbound semi. That pickup driver was also declared dead at the scene. The cause of the crash is under investigation.
