A 7-year-old California boy was killed in a car crash on Highway 97 north of Chiloquin, according to Oregon State Police.

The preliminary investigation showed a northbound Honda Odyssey driven by 33-year-old Yuriel Lucatero Campos of San Ysidro, Calif. lost control due to icy conditions, crossed into the oncoming traffic and was hit head-on by a semi.
Lucatero Campos and four passengers were taken by air ambulance to Sky Lakes Medical Center in Klamath Falls.
A fifth passenger, a 7-year-old boy, died at the scene, OSP said.
The driver of the semi was not injured.
OSP said the highway was reduced to one-lane for six hours.
