A man accused of attacking a security guard while armed with a knife was fatally shot Thursday at a Newburgh emergency room. Fire officials say they were initially dispatched to Montefiore St. Luke’s Cornwall Hospital after a fire alarm box was pulled in the lobby. Hospital staff determined that a disorderly individual was responsible for pulling the alarm. When confronted, he brandished the knife and began to attack the security guard. The man, now identified as 45-year-old Carlos Oritz, was hit by a single round fired from the guard’s gun. Police arrived at the scene at around 11:07 p.m. Oritz was later pronounced dead. Authorities say a woman near the altercation also sustained injuries not considered life-threatening. No charges have been filed as of Friday morning. Anyone with additional information is asked to call 845-569-7519.
