CHICAGO (AP) -- A federal investigation of a crash that killed an Illinois State Police trooper has found the driver of the semi-truck that slammed into his cruiser had been working more than 14 hours and fell asleep at the wheel.
The Chicago Sun-Times reports Thursday that Federal Motor Carrier Safety Administration records show the driver and United Van Lines have been fined for violating rules requiring drivers to get adequate rest.
The newspaper says the 26-year-old driver worked for Barrett Moving and Storage, an agent of United Van Lines. He has not been charged in connection with the March 28 crash in Chicago's northern suburbs. Trooper James Sauter of Vernon Hills died in that crash.
United Van Lines says it's cooperating with authorities and is "deeply saddened" by the trooper's death.
