One person is dead after his car crossed the center line and drove into a garbage truck going the other way in Michigan City.

The crash happened at about 1:45 p.m. Monday on U.S. 20 west of Johnson Road, according to the LaPorte County Sheriff’s Department.

Investigators say a Buick suddenly crossed the center line and drove right into a garbage truck head-on. The driver of the Buick was killed instantly while the garbage truck ended up in a water-filled ditch. A hydraulic tank on the garbage truck was ruptured, leaking fuel into the ditch. HazMat crews quickly contained the fluids and kept them from entering nearby Trail Creek.

Crash reconstruction investigators are still investigating why the car drove into the path of the garbage truck. However, it is being investigated as a possible “intentional” crash, according to the LaPorte County Sheriff’s Department.

The coroner’s office has not been able to get a hold of the person’s family.

All four lanes of U.S. 20 were closed for about two hours before lanes started gradually re-opening. However, crews were still at the scene at 6 p.m. clearing debris from a westbound lane.
