Feds probe deadly California freeway collision

RED BLUFF, Calif. (AP) — Federal authorities are wrapping up the initial stages of their investigation of a fiery collision between a FedEx truck and a tour bus carrying high school students that left 10 dead in Northern California.

National Transportation Safety Board Spokesman Keith Holloway said Sunday that investigators have gathered much of the key evidence from the crash site and continue to collect records. The entire probe could last more than a year.

Initial evidence suggests the truck driver had veered across an Interstate 5 median, sideswiped a sedan and crashed into the bus without applying brakes.

Investigators will look for possible reasons, including mechanical failure and if the driver was incapacitated.

The NTSB is also looking at whether fire safety measures could have allowed more of the 48 bus occupants to escape unharmed.
