An Indiana couple was leaving their wedding reception and stopped to help another driver stuck in a ditch when the groom and the other driver were struck by a car and killed.

The bride was still in her wedding dress.

William "Riley" Knight, 49, and his new wife Nikki stopped to help the woman around 11:45 p.m. on Saturday near Crown Point, Ind., the Chicago Sun-Times reported.

Knight and Linda Darlington, 42, were standing by the road when they were struck first by one eastbound car, and then by two more cars that followed, the paper reported. Nikki was sitting in the Knights' truck.

"I went from a being a newlywed to a widow in less than 48 hours — the highest high to the lowest low," Nikki told the Sun-Times. "It's a blur."

Knight, a former U.S. Ranger, also left behind two daughters, a stepson and stepdaughter.
