A Park Forest woman was killed when two semi-tractor trailer trucks collided with her car on Interstate 80 in New Lenox, officials said.

Mary E. Maher, 60, of Park Forest, was traveling west in a Toyota Corolla around 2:15 p.m. Wednesday when she struck the back of a semi that had come to a stop on I-80 at Interstate 355, according to state police and the Will County coroner.

A semi behind Maher failed to stop and crushed the Corlolla against the first semi, according to state police.  The second semi also sideswiped a vehicle in the eastbound lane, state police said.

Maher was pronounced dead at 3 p.m. No other injuries were reported.

An autopsy is scheduled for later today by the Will County coroner's office.
