Motorcycle Vs. Deer Crash with Injuries 

On 07/24/2026, at 3:43pm, the Grant County Sheriff's Office received a report of a motorcycle crash with injuries on Highway 133, near Carter Lane, in Waterloo Township.  

When deputies arrived on scene, they learned Roger and Tammy Adkins, of Eldridge, Iowa, were southbound on Highway 133 in Waterloo Township, on their 2023 Harley Davidson motorcycle. As they were traveling south, the motorcycle struck a deer in the roadway and turned on its side. The motorcycle slid approximately 75 yards, ejecting both from the motorcycle. Neither of the riders were wearing helmets, and both received severe injuries as a result of the crash.  

Both riders were treated at the scene by Cassville EMS, and then transported to UW-Madison Hospital by helicopter. The crash remains under investigation.  

The Sheriff's Office was assisted at the scene by Cassville Fire Department, Cassville EMS, University of Wisconsin MedFlight, University of Iowa AirCare, and Arrow Towing of Lancaster.  

Two-Vehicle Crash with Injuries 

On July 25th, 2026, at approximately 11:20am, the Grant County Sheriff's Office was notified of a two-vehicle crash with injuries at the intersection of Highway 11 and Highway 35, in Jamestown Township.  

When deputies arrived on scene, it was determined Anna Haldiman, 22, of Dubuque, IA, was eastbound on Highway 11 at the intersection with Highway 35, in her 2018 Jeep Cherokee. At the same time, Brian Denemark, 56, of Cascade, IA, was driving his 2019 Honda Civic westbound on Highway 11. Denemark was stopped in the intersection waiting for traffic to clear so he could turn south onto Highway 35.  

The traffic lights for Highway 11 turned from yellow to red, and as Denemark attempted to complete the left turn, Haldiman tried to continue eastbound through the intersection on Highway 11. The front of Haldiman's Jeep collided with the front of the Honda Civic. The Jeep then left the roadway on the south side of the intersection and entered the ditch where it struck a tree and flipped onto its passenger side. Denemark's Honda Civic came to a rest in the middle of the intersection.  

Both vehicles sustained significant damage. Denemark sustained minor injuries and refused medical transport after being evaluated at the scene. Denemark's 22 year old passenger was not injured.  

Haldiman sustained non-life threatening injuries and was transported to a Dubuque hospital via ambulance. 

The Grant County Sheriff's Office was assisted at the scene by Dickeyville EMS, Hazel Green EMS, Jamestown First Responders, Jamestown Fire Department, East Dubuque Police Department, Jo Davies County Sheriff's Office, and Donnie's Tire and Tow.  

The crash remains under investigation.
