The State Highway Patrol says a trooper injured while investigating a fatal pileup on the Ohio Turnpike that killed three people is in serious but stable condition. A series of crashes Wednesday involved at least 50 vehicles on the turnpike after a blast of winter weather struck. The Patrol says trooper Andrew Clouser from the Milan Post was being treated at a Toledo hospital. The 29-year-old Trooper has been with the Patrol just over a year. The Patrol also says Clouser was injured responding to one of the first accidents when he was pinned between two vehicles. Pileups stretched across a 2-mile section in the eastbound lanes midway between Toledo and Cleveland. Another series of crashes about 10 miles to the east shut down westbound lanes near Sandusky.
