Is mercy hospital haunted

If you are talking about the one in Laredo, Texas, I can only say that "It is believed to have some paranormal activity" going on. I live in Laredo and know about it's history. Just remember that every hospital is a place of death, so it is likely that all hospitals may house a ghost or two. I do know alot of people try to sneak in with handheld cameras to "catch" activity, but nothing concrete yet since there is a big sign around the property stating that "Trespassers will be prosecuted". The only way to really get an answer is to try to sneak in yourself and ask questions when you get in, although you are running the risk of being arrested. Also you got to be careful, there is no electricity so elevators, of course, will not be functioning so you will have to take the stairs.
