@thecrimedesk: A former high school basketball star was bludgeoned to death with a sledgehammer by a coworker who admittedly did not like her, prosecutors alleged. Amber Czech, 20, was found dead at her work station at a Minnesota manufacturing plant around 6am Tuesday morning. Surveillance cameras inside the Advanced Process Technologies facility recorded the moment she was brutally attacked by her colleague, prosecutors said. David Bruce Delong, 40, left his work station, walked over to Czech, picked up a sledgehammer and hit her to the ground, according to charging documents obtained by the Daily Mail. The 20-year-old welder was knocked to the ground, but Delong continued to hit her four more times, the court filing said. Czech died of blunt force trauma to her head and corresponding blood loss. #news #crime #minnesota #coworker
