A Munster woman escaped serious injury last night when she flipped her vehicle onto its roof. Preliminary investigation by Trooper John Landowski revealed at approximately 8:35 p.m., Sunday, April 7th, a 2010 Cadillac Escalade was west bound on I-80/94 when for unknown reasons the driver, Betty Markovich, 87 of Munster, Indiana, went off the roadway and struck an attenuator that was in the gore area (this is the area that separates the main line and a ramp) to the Kennedy Avenue ramp. The Cadillac hit the attenuator with its right front, causing the front right wheel to separate from the car. This caused the Escalade to overturn and come to rest on its roof, facing north. Markovich was taken to Munster Community Hospital with non-life threatening injuries.
