(Mishawaka, IN) - One person was killed in a collision between a UPS semi-truck and passenger vehicle on the Indiana Toll Road outside Mishawaka yesterday.

According to police, it appears the brakes on the UPS truck, pulling two trailers, locked up.  The semi came to stop with one of the trailers in the one of the westbound lanes, leading to a car approaching from behind striking the rear corner of the trailer. A passenger in the car was pronounced dead at the scene while none of the drivers were injured.

What caused the brakes to lock will be determined from an inspection.

The westbound lanes were closed for several hours after the Tuesday morning collision.  Per the authorities, neither alcohol nor drugs appear to have been involved, but the crash remains under investigation.

So far, the name and age of the victim has not been released.
