A 20-year-old welder was beaten to death with a sledgehammer at her Minnesota workstation by a male coworker who admitted he 'didn't like her' and had been planning to kill her for some time.
David Bruce DeLong, 40, walked from his workstation to Czech's area around 6am on 11 November, grabbed a sledgehammer and struck her repeatedly in the head according to charging documents. Surveillance footage shows he hit her once whilst she was standing, then four more times after she fell to the floor.
