On Tuesday, May 06, 2025, at approximately 5:22 PM, the following events involving a Walworth County Sheriff’s Patrol Deputy occurred in the City of Delavan, located in Walworth County.

Deputy Chorneyko was operating his marked patrol squad, Eastbound on Hwy 50 to the West of the intersection of County Hwy F, North, in a routine, non-emergent manner. Deputy Chorneyko observed a red truck operating Westbound on Hwy 50, coming at him head-on.

This vehicle appeared to be attempting to pass other westbound vehicles in a marked no- passing zone. Deputy Chorneyko tried to take evasive action to avoid a head-on collision with the red truck but was unsuccessful and subsequently sideswiped by the truck. Deputy Chorneyko’s squad became inoperable and came to rest in the roadway, with extensive damage and airbag deployment. The red truck continued westbound and sideswiped another eastbound vehicle, which was originally two vehicles behind Deputy Chorneyko’s squad. The red truck then collided head-on with a third vehicle immediately behind the second vehicle that had been struck. All vehicles remained on-scene and were inoperable as a result of the crash.

A Good Samaritan immediately stopped and assisted Deputy Chorneyko, who required assistance in getting out of the squad, due to the extensive driver’s side damage. Upon exiting his squad, Deputy Chorneyko was advised by other Good Samaritans who were stopping to assist that the red truck was on fire and the driver was trapped. Deputy Chorneyko immediately went to the aid of the driver and sole occupant of the red truck, who had just hit him. There was no fire, but the driver was trapped in the wrecked vehicle and needed medical attention.

Law enforcement from the City and Town of Delavan Police Departments and the Walworth County Sheriff’s Office were arriving and provided first aid to the injured drivers and sole occupants from the other two vehicles. All injuries from this crash were non-life-threatening.

Highway 50 between Northshore Drive and Hwy F, North, was closed for an extended period of time while the Wisconsin State Patrol conducted a traffic crash investigation. The City of Delavan Police Department remains the lead agency and point of contact for this incident.

A medical emergency by the driver of the red truck is believed to be a significant contributing factor to these events.

The community’s willingness to stop and assist our injured Deputy and other drivers in this crash did not go unnoticed and is greatly appreciated. We extend our sincere thanks to the citizens involved, the City of Delavan Police and Fire Department, the Town of Delavan Police and Fire Department, and the Wisconsin State Patrol.
