On Saturday night, a chef stabbed his co-worker in the back at a Massachusetts mall P.F. Chang’s, and there’s unfortunately nothing metaphorical about that sentence: Local police say Jaquan Huston and Elivelton Dias, two of the restaurant’s chefs, had gotten into some kind of argument, and that just as the dinner rush was starting, Huston came up behind Dias in the kitchen and fatally stabbed him with a knife. Dias, a 38-year-old who the Globe notes had fled Brazil to escape the country’s violence and just became a dad last week, was quickly transported to the closest hospital, though doctors pronounced him dead upon arrival. Huston allegedly fled the scene and was apprehended at his home, and he’s being charged with murder. P.F. Chang’s says it’s committed to providing care to Dias’s family, as well as to its traumatized employees.
