(Barrington, RI) -- Authorities are blaming high carbon-monoxide levels at a Barrington prep school on a microwavable dish. Authorities at first thought there was a carbon-monoxide leak in one of the dormitories at Saint Andrews School around 5:25 p.m. yesterday. Investigators learned that a student was making a beef dinner called a hotpot that his parents sent him. The dinner was confiscated and four students were checked out at the scene.
