COOPERSTOWN, Wis. — An Iron River woman was pronounced dead at the scene of a car crash Saturday morning in Cooperstown Township in northern Wisconsin.

Manitowoc County Sheriff’s Office deputies were dispatched at about 6:14 a.m. Saturday to the I-43 northbound ramp at County Highway K within Kossuth Township for a report of two men physically fighting outside a parked 2006 Honda Accord. Prior to deputies arriving, the men entered the vehicle and continued northbound on I-43. Around 6:23 a.m., deputies and EMS were informed that the vehicle in question was involved in a rollover crash on I-43 south of Schley Road within Cooperstown.

The preliminary investigation indicates 33-year-old Corey Knepp from Republic, Michigan, was operating the vehicle when it abruptly entered the east ditch and overturned. As a result, 29-year-old female Emily Lapointe was ejected from the vehicle and pronounced dead at the scene. Manitowoc County Coroner Curtis Green indicated blunt force trauma was a contributing factor to her death.

Knepp and his twin brother, Tyler Knepp, were both transported by ambulance to Aurora BayCare Medical Center in Green Bay, Wisconsin, for non-life threatening injuries, a press release from the Manitowoc County Sheriff’s Office states.

The Knepp twins were arrested for possession of drugs as a repeater, possession of drug paraphernalia as a repeater and disorderly conduct. Following a bail hearing Monday, both men were still in Manitowoc County Jail on a $2,500 cash bail as of Tuesday.

The initial physical altercation and cause of the crash are still under investigation by the Manitowoc County Sheriff’s Office, Wisconsin State Patrol and Manitowoc County Coroner’s Office.
