Former NFL player Phillip Adams -- who slaughtered 6 people before taking his own life -- had a severe case of CTE when he went on a violent rampage, according to a neuropathologist.
Ann McKee, a top brain doc who runs the CTE Center at Boston University -- the nation's premier facility when it comes to examining brains -- released her findings after thoroughly examining Adams' brain.
Adams was suffering from stage 2 CTE, considered a "severe" case, because it was found in both frontal lobes of his brain.
