ORLAND, Glenn County (CBS SF) -- Federal investigators will look at surveillance video of a FedEx driver hours before his truck crashed into a tour bus last week, killing him and nine other people on Interstate 5 north of Sacramento.
The day of the crash outside of Orland in Glenn County, FedEx driver Tim Evans drove from Sacramento to Humboldt County to make a delivery in the town of Weed, where he also picked up two new trailers before heading back South.
Investigators will look back 72-hours at cell phone records and surveillance video of Evans to look for clues into the crash.

NTSB investigators say evidence on the asphalt doesn't indicate Evans hit the truck's brakes before crossing the median, sideswiping a sedan and slamming into the bus.
Skid marks on I-5 suggested the tour bus driver did brake and swerve to try to avoid the impact.
Both the big rig and bus both have black box-like devices called electronic control modules, but they may not be much help to investigators.
"The one on the truck was destroyed - destroyed in the post impact fire. However, we can look at aspects of steering, and other pieces that did survive to possibly get a sense of the speed range and the revolutions of the wheels to maybe even know the direction they were in," said Mark Rosekind of the NTSB.
