NTSB: Trucker Had Little Sleep Before Crash That Killed 7 Kids

Investigators say the driver of the tractor-trailer that failed to stop for a car and a school bus last week, killing seven and injuring 11 others, was not drunk, but had barely slept for 34 hours.

Thursday afternoon, federal, state and local investigators announced preliminary results of their crash investigation, finding no mechanical failure, no obstruction that would have prevented seeing the stopped vehicles, and no evidence of drug or alcohol use by the truck driver.
