What Happened to Bartholomew L. Chabotte?
The fatal collision happened early Tuesday morning as Chabotte rode a black 1992 Harley-Davidson XLH1200 motorcycle through the intersection of State Highway 23 and the northbound U.S. Highway 151 Exit 40 ramp.
According to the preliminary account released by the Iowa County Sheriff’s Office, a semi-truck traveling north on U.S. Highway 151 exited at Exit 40 and continued through the intersection. Investigators reported that the truck failed to yield and struck Chabotte’s motorcycle.
The motorcyclist reportedly had the right-of-way and was traveling through the intersection when the collision occurred.

Dashcam Footage Helps Investigators Identify the Truck
A key development in the investigation came when deputies obtained dashcam footage from another semi-truck parked nearby.
According to the sheriff’s office account reported by local media, the footage provided investigators with information about the truck that had left the scene, including a description of the vehicle.
Later that morning, at approximately 11:45 a.m., a detective sergeant spotted a matching 2022 white Freightliner traveling southbound on U.S. Highway 151 near Ridgeway.
Deputies stopped the truck without incident and identified its driver as 49-year-old Ahmed Mustefa Deneto of Iowa City, Iowa.
The footage was an important investigative lead because it helped authorities narrow their search for the vehicle involved in the fatal collision. The case was then referred for continued investigation and prosecutorial review.
Truck Driver Arrested on Felony Hit-and-Run Charge
Authorities reported that Deneto was taken into custody and booked into the Iowa County Jail on a felony charge of hit and run involving death under Wisconsin Statute 346.67(1).
The charge relates to the reported departure from the scene after the collision that killed Chabotte.
A criminal charge is an allegation, not proof of guilt. Deneto is presumed innocent unless and until guilt is established through the legal process.
The Iowa County Sheriff’s Office, Wisconsin State Patrol and Iowa County District Attorney’s Office are involved in the continuing investigation and review of the case.
Further court information or official updates may clarify the next steps in the proceedings.
