A 57-year-old man is dead after his SUV left U.S. Highway 45 in Bristol and slammed into a tree on Wednesday morning, according to the Kenosha County Sheriff’s Office. Brian Nielsen was flown to a Milwaukee hospital following the crash but died from his injuries that evening.

Deputies were called to the 9800 block of U.S. Highway 45 around 9:52 a.m. Wednesday for a single-vehicle crash, as reported by wearegreenbay.com. A preliminary investigation found that Nielsen was driving south on the highway in his blue 2017 Ford Escape when the vehicle left the roadway, entered a ditch and eventually struck a tree, according to the Kenosha County Sheriff’s Office.

The Bristol Fire Department extricated Nielsen from his vehicle and transported him to the Kenosha County Center, where Flight For Life then airlifted him to Froedtert Hospital in Milwaukee. He died there Wednesday evening due to the serious injuries he suffered in the crash, per the same account relayed by the sheriff’s office.

Medical Emergency Still Under Review

The Kenosha County Medical Examiner’s Office is examining whether Nielsen may have experienced a medical emergency before the crash, the sheriff’s office said. No other information was available as of the initial report, and the sheriff’s office said the investigation into the incident remains ongoing.

Kenosha County Sheriff David Zoerner said authorities are working to determine the circumstances that led to the crash. He offered condolences to Nielsen’s family and loved ones, and thanked witnesses who stopped to assist as well as the emergency personnel who responded to the scene.

What Comes Next

As Channel 3000 notes, the case remains an active investigation, with the medical examiner’s findings still pending. No further details on the cause of the crash have been released.
