A 17-year-old was injured and four vehicles were damaged by objects thrown from a Bristol overpass onto the Indiana Toll Road in April.

The objects — including chunks of concrete, a white mailbox and a gallon container of windshield washer fluid — were thrown from the C.R. 19 overpass in Bristol just before midnight Friday, April 22, the Indiana State Police said. The vehicles were hit near the 97.1 mile marker on the Toll Road.

The objects didn’t cause any vehicle crashes.

Indiana State Police investigators are looking for the person or people who threw the objects. The person or people responsible could face felony charges.

Anyone with information is asked to contact the Indiana State Police Toll Road Post at 574-206-2931.
