A young welder named Amber Czech was killed inside her workplace in Cokato, Minnesota, on 11 November 2025, shortly after 6 a.m. The attack happened at Advanced Process Technologies, where she worked with David Bruce Delong, the man who later admitted to killing her.
Investigators say he acted because he 'didn't like her' and had planned the murder. The killing unfolded inside the facility, and the details show how a routine shift turned into a fatal assault.
