NTSB Examining FedEx Driver's Last 72 Hours Before Orland Tour Bus Crash

ORLAND (CBS13) — Federal investigators are retracing a FedEx driver's last 72 hours before a deadly Orland tour bus crash as his family and friends are trying to cope with losing him.

The last three days of Tim Evans' life are under examination, as investigators comb through cellphone records and gas station surveillance video along the truck's route to determine if he had enough rest.

Meanwhile, his Facebook page collects the thoughts and remembrances in the days following the accident that took his life, including a post from his wife:

"He was my best friend, my teammate, my rock, my partner in crime, my everything. He was my saving grace. He saved me from myself. He believed in me when I couldn't and never ever let me fail."

On Thursday, Evans traveled from Sacramento to Weed, Calif. to make a delivery—a more than six-hour round trip. After picking up two semi-trailers, he headed back to Sacramento.

On the drive back, his truck would cross the median on Interstate 5 in Orland. Investigators say there's no evidence Evans hit the brakes before he sideswiped a sedan and crashed into a tour bus.

But skidmarks on the road do suggest the driver of the tour bus, Tala Lealao-Taiao, did try to brake and swerve before the crash that took her life.

Neighbors say Evans' family is too distraught to go on-camera. Instead, we're left with the Facebook post from his wife that gave the world a glimpse into the who the FedEx driver was, ending her comment with:

"He was perfect for me, a gift from God and was taken too soon. I don't understand...I never will, but I do know that because of his LOVE, I will go on and be a magnificent WARRIOR. RIP beautiful soulmate."

The National Transportation Safety Board said it requested video from first responders' dashboard cameras to see how the fire spread, and how the survivors escaped. They are still working on gathering information from the tour bus' black box.
