Pretty good show! I miss investigating Pennhurst and have dreams of roaming around the place. We were able to get in shortly after Ghost Adventures episode aired in 2009. The owners had opened it up to us and basically had free reign of the place - tunnels, Administration and all other buildings including the morgue.
The previous owner was a skeptic and didn't fully believe until he went in one day with 2 friends. He heard a gunshot while using a real time EVP device which acts like your DVR. You can pause rewind etc. He heard the gunshot in his headphones but the other 2 guys didn't. He rewound the audio and let the others listen. A few years later the owner found out that a patient was shot there - not sure of the whole story.
The history of that place is pretty sad. 80-100 patients to a building with 2 nurses to watch over everyone. Some kids weren't even taken out of their cribs to crawl or walk which atrophied their limbs. Back in the day, even kids with cerebral palsy would be tossed in with kids of various learning disabilities and down-syndrome when they didn't belong. Any kid that had a biting problem and bit others would have their teeth removed. Kids that could talk or walk would actually degrade once there and stop talking or walking because of the conditions. Parents would drop their kids off at the door and that would be the last they'd see them because that's what people did then.
