A man and his young son remained hospitalized Monday, one week after the father caused a three-vehicle crash on Lakeville Highway that closed the major route for hours and injured six people.

Chase Harris, 5, still is in Children's Hospital in Oakland. He's being treated in the intensive care ward for numerous major injuries including brain trauma and a broken pelvis.

The boy was considered to be in critical but stable condition, according to the CHP.

Wade Harris, 37, was at Santa Rosa Memorial Hospital being treated for numerous broken bones and other major injuries.

They are residents of the small Humboldt County community of Loleta.

On April 28, Harris was driving north along Lakeville Highway about noon when his Pontiac Grand Prix crossed double yellow lines.

As it moved into the other lane the car clipped one vehicle and then smashed head-on into a large truck.

Harris and his son were the most seriously hurt and CHP officials initially said the injuries could be life threatening.

What caused Harris to drive out of his lane remained under investigation, including whether he was impaired. Blood test results were pending, according to the CHP.
