The Lake County Sheriff's Department said William Knight, 49, of Crown Point, married earlier in the day, was on his way home with his bride Saturday when he stopped to help Linda Darlington, 42, of Crown Point, whose car went into a ditch, the Chicago Tribune reported Monday.
Darlington was making her way up an embankment as Knight stood on the side of the road when a passenger vehicle struck them, investigators said.
Two vehicles "trailing behind the initial vehicle also ran over the two pedestrians," the sheriff's office said.
Knight's wife, Nikki Knight, was not injured, officers said.
"I went from a being a newlywed to a widow ... the highest high to the lowest low," she told the Chicago Sun-Times. "It's a blur."
Knight and Darlington were pronounced dead at the scene, the Lake County coroner's office said. Autopsies indicated they died of blunt-force trauma.
Police said all drivers involved in the crash stayed at the scene and tested negative for alcohol. The Sun Times said the sheriff's office had not filed any charges as of Sunday night.
