Wisconsin Man Charged with Homicide After Fatal Attack on Family Walk

Jeffrey Endres, 49, from Cottage Grove, Wisconsin, was charged with first-degree intentional homicide and other counts after allegedly driving his car intentionally into Dr. Kami Hansen and her family, killing Hansen and the family dog in an act described by prosecutors as vigilante justice. The incident occurred on April 28 when Hansen, her husband, their son, and their dog were out walking; multiple witnesses reported seeing Endres accelerate toward the family before the crash. Prosecutors revealed the attack was motivated by a "sensitive crime" involving the children of both families, which led to a severed relationship between Endres and Hansen's family. Hansen's husband sustained minor injuries, while their son required surgery for a concussion, and the dog died on the scene. Endres was found dead in his jail cell shortly after pleading not guilty, with authorities investigating the cause of his death. The case highlights a tragic escalation of a personal dispute to deadly violence within a close-knit community.
