An Illinois man was killed in a crash on the Indiana Toll Road.

The collision happened around 12 p.m. on Monday, May 1, near the 143 mile marker, which is just west of I-69.

Once on scene, initial arriving officers found a Buick LaCrosse passenger car and a Dodge Ram pickup truck, both with heavy front end damage blocking the eastbound lanes.

The driver of the Buick LaCrosse, identified as Jesse Charles Cox, 33, from Chicago, was found to be unresponsive. A nurse that was passing by stopped to aid officers in rendering medical assistance, but efforts were unsuccessful. Cox was pronounced dead at the scene by the Steuben County Coroner.

The Ohio man driving the Dodge Ram pickup truck, and his passenger were both injured, but were able to speak with officers.

The preliminary crash investigation found that prior to the crash, the Buick LaCrosse was traveling west on I-80/90. For an unknown reason the Buick veered off the traveled portion of the westbound lanes towards the median, crossed through the grass median, entered the eastbound lanes of traffic, and then crashed head on into the Dodge Ram truck.

Neither alcohol nor drugs are suspected at this time, but as required by state law, both drivers were subject to chemical testing.

Investigators say that vehicle speed combined with the wet road surface conditions was the likely cause for the initial loss of control. Cox was not wearing a seatbelt at the time of the crash.

As a result of the crash, the eastbound lanes of I-80/90 had to be shutdown at the 143mm for approximately two hours.
