KEWASKUM, Wis. (CBS 58) -- One person is dead and another seriously injured following a motorcycle crash in Kewaskum Sunday night, August 8. 

It happened around 5:17 p.m. near Hwy 28 and Cty Tk V in the town of Kewaskum.

The Washington County Sheriff’s Office says dispatch received multiple calls of a motorcycle crash. 

They arrived to find a woman in her late 40’s from Jackson in the southbound lanes with significant injuries, and a man, also in his late 40’s from Jackson, was found down the embankment receiving CPR from a Good Samaritan. 

The motorcycle was located south of both patients on Hwy 45.

Lifesaving efforts on both patients were taken over by law enforcement and Kewaskum Fire, with additional assistance from West Bend Rescue and Lifestar Rescue.

The man died on the scene.

The female was conscious on scene and was transported by rescue to Froedtert Wauwatosa. She is in stable condition.

The initial investigation showed that the motorcycle was operated by the man and the woman was the passenger.

The motorcycle was headed southbound on Hwy 45 coming into Kewaskum when the operator lost control, ejecting both occupants.

Weather is believed to have played a significant role in the crash as there was a very strong storm front and heavy rains that were moving through the area during the time of the crash.

At this time it is believed that no other vehicles involved in the crash, and the actual crash is believed to have been unwitnessed.

Hwy 45 in both directions between Hwy 28 and Cty Tk V was shut down for approximately 3 hours for rescue and the investigation.

This accident is still under investigation by the Sheriff’s Office Accident Reconstruction Team.
