CEDAR GROVE, Wis. A fiery crash on a foggy interstate highway involving about 25 vehicles killed some people and sent at least 12 others to hospitals Friday, authorities said.
"I have been told there are fatalities. No number given," said Robert Young, deputy superintendent of the Wisconsin State Patrol. "There are a number of people injured. Everything is pretty much confusion."
Sheriff's authorities closed parts of Interstate 43 near the Sheboygan-Ozaukee county line after the 7:30 a.m. accident.
There was no immediate word from three area hospitals on the extent of the victims' injuries.
The accident involved at least 25 vehicles in both the southbound and northbound lanes. At least eight vehicles were on fire, Sheboygan County Sheriff's Captain Dave Adams said.
"It's very chaotic out there," he said. "It's very foggy."
A hazardous materials team was called to the scene because a semi carrying carbon dioxide was in danger of tipping over, Adams said.
Bonnie Depies, who works at a Citgo gas station about a mile from the crash scene, said fire departments had put out the fires by midmorning.
"It was very foggy when I got to work this morning, but you could see black smoke through the fog," she said.
Workers at the service station can normally see vehicles' lights on the highway in the early morning, but fog obstructed those lights Friday, Depies said.
