Columbia County, WI – Authorities have identified the two men killed in Tuesday’s fatal crash near Arlington. According to the Columbia County Sheriff’s Office, 47-year-old Gregory Dellmann and 40-year-old Jesus Cabrera Gallegos, both of Poynette, died after their vehicles collided on WIBU Road near Kampen Road around 3 p.m. on October 21, 2025.
According to the Sheriff’s Office, multiple 911 calls reported the crash, describing heavy vehicle damage, entrapment, and one car on fire.
