EASTPOINTE, Mich. (AP) — A McDonald's employee returned to her Detroit-area restaurant after an argument Thursday and fatally stabbed a co-worker multiple times, police said. A breakfast customer licensed to carry a gun fired a warning shot and stopped the 26-year-old woman as she tried to flee, Eastpointe police Lt. Alex Holish said. “For a verbal dispute to turn into this is ridiculous,” Holish told the Macomb Daily.
