Police say two people are dead after a head-on crash in Boone Township between Boone Grove and Hebron Sunday night. Porter County Sheriffs Police say a southbound Buick LeSabre driven by 56-year-old Laurel Donner of Valparaiso and a northbound 2002 Chevy Malibu driven by 33-year-old Jessica Trzepacz of Michigan City collided head-on at 700 West State Road 2 at about 7:30 pm. Both drivers were pronounced dead at the scene. A passenger in the Buick, 62-year-old John Donner of Valparaiso, was transported to an area hospital with non-life-threatening injuries, police say. Police also say the investigation is still ongoing to determine which vehicle drove left of center, and toxicology tests will be conducted by the coroner's office to determine whether drugs or alcohol were a factor, according to a news release from the Sheriffs office today. Porter County Police were assisted at the scene by Valparaiso and Hebron Police, the Porter County Coroners office, Porter EMS, and fire departments from Hebron, Boone Grove and Lakes of the Four Seasons.
