JOLIET, Ill. (AP) — A semi-truck driver involved in crash that killed four people southwest of Chicago was driving too fast and falsified entries in a logbook tracking the number of hours he spent behind the wheel, authorities said Tuesday.

Investigators believe the semi-truck was speeding on Interstate 55 near Channahon when it struck several vehicles stopped in a construction zone, state police Cmdr. Randy Ness told reporters after Monday’s crash. Francisco Espinal Quiroz, 51, of Leesburg, Indiana, was charged with failure to reduce speed to prevent an accident and willfully making false entries in his logbook.
