Early one morning i had a patient pass away around 7:30 right when change of shift occurred. I was assigned this patient only to perform morgue care after the family came in to pay their respects. I took a CNA with me to perform the morgue care. The patient was in Bed A, while Bed B, by the window, was empty. While we were getting ready to place him in the bag, Bed B's television suddenly turned on displaying static and then a movie. Neither of us were anywhere near the tv controls. We both said, "Did you do that?!?" When both of us realized neither of us had turned the television on, we hurried up and finished as fast as we could and got the heck out of that room! Scary!
