A three-vehicle crash at 8:20 a.m. Thursday sent two people to the hospital; one of them via Flight for Life.
According to a press release from the Caledonia Police Department, Sheryl Bink, 20, of Racine, was driving a Pontiac Grand Am east in the 7100 block of Five Mile Road when she hit a trailer parked on the side of the road. Bink then hit an on-coming van and flipped over.
She had to be extricated and was taken by Flight for Life to Froedtert Hospital where she is in serious condition.
John Pavlik, 57, was driving the van, and he was transported to Wheaton Franciscan via ambulance with non-life threatening injuries.
Five Mile Road was shut down in both directions for about two hours.
Caledonia PD continues to investigate what caused the accident but do not believe alcohol was a factor.
Editor's Note: In an earlier version of this story, we stated that police were investigating if alcohol or inattentive driving were a factor in the accident. When we updated the story with information from the release from Caledonia PD, we neglected to clarify that alcohol was probably not a cause. We have since corrected the information and regret the error.
