The hospital has been haunted since they closed it, and they say that you can still hear voices of all the people that died in the morgue.
It is said that in the old Mercy Hospital in Laredo there have been sightings of a nun walking around in the fourth floor. Now that the hospital is no longer open, many people have gone into the hospital and say that there is blood on the walls and there is a horrible odor in the morgue. Some people have said that when they go into the hospital they hear noises and footsteps from the third floor and, from what I have heard, no one has been able to go any further than the second floor.
It is said that dead nuns and patients that never made it out alive supposedly haunt the Old Mercy hospital. I have a friend that told me that he and his dad went inside and they could both feel a strong presence of someone watching over them, and they actually saw a man dressed like he was in prison. They looked away for a second and he was gone.
