Hearing "You need to come deal with a patient issue!" Was my first inkling something was wrong. I put on my mask and headed down the stairwell. Something was seriously amiss. Through the window I saw a large group of staff and patients gathered outside. “There’s a person in the building with a knife,” a manager said. “We don’t know where he is.” Managers were clearing the building, room by room. Ten police cars with lights flashing were scattered around the parking lot.
