MICHIGAN CITY, Ind. -- Cars were mangled, and some were burned despite the blowing snow. Other vehicles were crushed between jackknifed semi-tractors, so entwined that it was difficult to tell them apart.
People were screaming, but emergency responders couldn't see many of them as they quickly tended to the victims amid frigid conditions.
Within seconds, traffic along snow-covered Interstate 94 in northern Indiana had become a mile-long pile of debris after whiteout conditions swept in during Thursday's evening commute. Three people were killed, and nearly two dozen were injured.
"It was such a devastating scene, you don't know where to start," said Coolspring Township Fire Chief Mick Pawlik, whose volunteer crew was among the first on the scene about 60 miles south of Chicago. "There were people in cars that you couldn't even see," he said during a news conference Friday. "But when people are stuck in their cars, they look at you like we're Moses: 'Part the water. Save us.' "
Rescue crews quickly set about prioritizing victims. Who needed help first? And who was beyond help? Firefighters worked quickly to keep victims warm as they extricated them. Just as importantly, Chief Pawlik tried to take their minds off what had happened, even though the dead weighed on his and other first responders' minds. "Those are the worst," he said. "You sit there -- they're the last ones to get out, but you know they're there."
The chain-reaction collision near Michigan City was triggered by a sudden burst of heavy lake-effect snow that took drivers by surprise, said Indiana State Police Lt. Jerry Williams. Within about 45 seconds, dozens of vehicles -- including numerous other trucks -- were crashing into one another.
In all, 46 vehicles, including 18 semis, were involved in the crash. Several cars were crushed between the trucks, and some slid underneath them.
The accident killed Chicago resident Jerry Dalrymple, 65, and a Michigan couple: Thomas Wolma, 67, and his 65-year-old wife, Marilyn, of Grand Rapids. More than 20 people were injured, including one who remained in critical condition Friday.
Chief Pawlik said the scene was "something that you'll never forget. It'll live with us forever." But he acknowledged that first responders were expecting worse. "We're lucky that there wasn't 20 people dead and three people injured," he said.
Among the survivors was Jeffrey Rennell, 48, who was driving home to Michigan from a business meeting in Chicago when his SUV suddenly started bouncing off other vehicles like a ping pong ball. Firefighters found it atop another vehicle and "encased in semis," Chief Pawlik said.
Mr. Rennell was trapped for more than three hours in the twisted remains of his Ford Explorer, according to his brother, Steve. He said his brother told him that he wasn't able to move much while trapped in his SUV, but he didn't think his injury was serious.
