COTTAGE GROVE, Wis. (WFRV) – A southern Wisconsin man is facing multiple felony charges after authorities say he intentionally drove into a family, killing a well-known chiropractor and the family dog and injuring a child.
According to a criminal complaint obtained by Local 5 News, 49-year-old Jeffrey M. Endres of Cottage Grove is charged with first-degree intentional homicide and two counts of attempted first-degree intentional homicide, among other charges, following the April 28 incident.

Shortly after 6:30 p.m., Cottage Grove police were sent to the 1300 block of Landmark Drive for a report of a vehicle that had hit multiple pedestrians. Officers arrived to find three family members and a dog hit while walking on the sidewalk.
The victims were identified as Dr. Kami Hansen, her husband, and their son. Kami later died at the hospital, while her son underwent emergency surgery and has since been released. Her husband did not require medical attention. The family dog was also killed.
Endres, whose SUV had overturned at the scene, was found nearby with injuries. When officers asked what had happened, he reportedly said he was “having a bad day” and declined to comment further. He told police he was driving about 25 mph on the way to a gas station and had lost control of the vehicle.
The husband told police the SUV appeared to accelerate directly toward the family, jumping the curb without braking. A witness also described the vehicle traveling at a high rate of speed, estimating it at 60 mph.
According to the complaint, the husband recognized the driver as Endres, a neighbor and family friend whose relationship with the Hansens had recently deteriorated. The rift reportedly stemmed from an investigation in March 2025 involving a sensitive incident between children involving both families.

Endres had recently submitted an open records request for the case, receiving the documents just hours before the crash, the complaint said.
“I’m confident he was intentionally trying to kill us or [my son] at least,” the husband told police.
Another person who reportedly saw the crash ran to the scene, saying, “He tried to hit you.”
Endres is charged with:
- First-degree intentional homicide
- Up to life in prison
- Attempted first-degree intentional homicide
- Up to 60 years in prison
- Attempted first-degree intentional homicide
- Up to 60 years in prison
