Illinois State Police held a news conference Thursday afternoon regarding the death of a trooper after a single car crash on Route 10 in Bondville.

The conference was held at Carle Hospital in Urbana, where Trooper Todd Hanneken was taken for treatment by helicopter. He was pronounced dead at 11:45 a.m., according to ISP Director Brendan Kelly.

Kelly said Hanneken was westbound on Route 10 when his squad car left the road. His car hit a light pole and then a tree. An investigation is still ongoing as to what caused his car to go off the road, WCIA reports. They do not believe there was anything suspicious, according to Kelly.
