Update Thursday: The Rock County Sheriff's Office has identified those involved in Wednesday's crash.
The driver who was killed in the crash has been identified as Matthew Kraft, 23, of South Wayne, according to a news release from the Sheriff's Office.
The injured passenger in Kraft's car has been identified as Joshua Swenson, 24, of Evansville, and the other driver has been identified as Gregory Schultz, 51, of Monroe.
One person was killed and two others were injured early Wednesday morning in a two-car crash in Rock County that closed a section of a state highway for about five hours, authorities reported.
The crash happened at about 5:20 a.m. on Wisconsin 59 just east of Wisconsin 104, about four miles southwest of Evansville, the Rock County Sheriff's Office said in a news release.
The person killed and two injured had to be extricated from the cars.
The person who was killed was pronounced dead at the scene, while one of the injured was flown by Med Flight to UW Hospital with serious but non-life threatening injuries, and the other taken by ambulance to Mercy Hospital in Janesville, also with serious but non-life threatening injuries.
Police said the initial investigation showed a 2007 Chevy Malibu was westbound on 59, approaching a sweeping curve near 104, when the car went onto the shoulder.
"The driver overcorrected and the vehicle began to spin counter-clockwise," said Capt. Jude Maurer in the release. "The vehicle then traveled sideways into the eastbound lane of traffic where it was struck by an eastbound Pontiac Bonneville."
The Malibu overturned onto its passenger side and the Bonneville ended up in a ditch.
The personal killed was the driver of the Malibu. He was not wearing a seatbelt.
One of the injured was a passenger in the Malibu and the other was the driver of the Bonneville.
Speed is believed to be a factor in the crash, according to the release.
The names of the victims have not been released pending notification of family.
