This week on Paranormal Lockdown, a paranormal reality TV series airing on TLC, paranormal investigators Nick Groff and Katrina Weidman visited one of the most haunted locations in the country — The Waverly Hills Sanatorium. The sanatorium originally housed tuberculosis patients, and around 8,000 people died in the building, with their bodies sent down a “body chute” into the building’s depths. The sanatorium first opened in 1910, and closed its doors in 1961.

Since then, there have been reports of shadow figures and disembodied voices haunting the hospital.

Groff and Weidman spent 72 hours confined in the sanatorium’s walls, with high-tech equipment to track down potential lingering spirits.

Groff was eager to spend the night in the 500-foot long body chute, but former FBI agent Ben Hansen cautioned them against it.

“I’m being really honest here,” Hansen warned. “I don’t think it’s safe. If it starts playing tricks on you and you get into a wild panic, it’s going to be a night of terror.”

This visit to the sanatorium is Weidman’s first, but Groff’s third; this time around, he came prepared with state-of-the-art tracking devices. One of them is a string of light sensors they placed on the body chute, which picked up some movement on its sensors. However, they need more than that to conclude that shadow figures were responsible for the movement.

At another point, both Groff and Hansen felt jolts of electricity spread through their bodies. With a thermal imaging camera pointed at them, it’s revealed that there was no heat emitting from their legs.

As the night goes on, events continue to unfold — events that chill them to the bone.
