Investigations continue into a collision that caused 4 people to suffer injuries over the weekend in Santa Cruz County. The just after 9 p.m. Saturday head-on crash involved a sedan and mid sized truck on Empire Grade Road just north of Smith Grade in Bonny Doon. 2 people were airlifted to an out-of-county trauma center and 2 others suffered minor injuries. C-H-P officers believe the wreck occurred after one car was trying to pass the other.
