ST. ALEXIUS, Mo. - The abandoned St. Alexius Hospital on South Broadway, in the Gravois Park neighborhood, looks as haunted as its history.

A real-life exorcism reported in 1949 inspired the 1973 movie "The Exorcist."

“All broken windows, every single one,” neighbor Felix Vargas said.

This includes a second-story window from which a mangled gurney was tossed out. It now sits near a sidewalk on the ground below.

Another neighbor, Deandrea Blaylock, called the area a “criminalized empire inside these vacant buildings.”

The campus appears to be vulnerable, with the gates forced open and multiple locations that allow easy access inside.

From the public sidewalk, you can see inside some patient rooms where the walls have been gutted for copper.

"I’ve noticed 20 different entry points onto the building after I called to have it boarded up,” Blaylock said.

An empty guard shack that was once protected is now a silent witness to mayhem. An ambulance entrance now looks like a junkyard.

Vargas says he often sees the people destroying the place.

Surveillance videos over the years show it all—from people crawling in to ramming through. The footage shows people coming and going at all hours.

What they may have access to is even more unsettling.

FOX 2 found dozens of patient identification cards scattered on the sidewalk. The cards contain patient names, addresses, phone numbers-and diagnosis such as prostate cancer and lung cancer.

Police responded Friday to reports of intruders, but no arrests were made.

The property owners responded to FOX 2, saying:

“With very limited financial resources, the hospital landowners did the best that we could to secure the building in cooperation with the City, such as installing the fence last year and having (a security officer) perform some security oversight for a couple of years, and she has been great. The hospital has been under purchase contract with two different developers over the past nine months. While waiting and hoping that they close, the hospital landowners are going to repair fence and put (the) security company back on the campus, which we hope and expect should help.”

“Something has to be done with this building, and I mean ASAP,” Blaylock said.

Meanwhile, residents are encouraged to call the Citizen’s Service Bureau if they see activity the city needs to tackle.
