Nikita Productions, Inc., San Antonio

In San Antonio, Texas, East Houston Street is a hotbed of paranormal activity. It's the site of two horrifying events that occurred in the '70s just blocks from each other, and their locations are now known as the Psycho Asylum and the Slaughterhouse.

The Psycho Asylum, formerly the River City Asylum, housed criminally insane and sick patients in the late '70s, but it didn't earn its nickname until December 1, 1978. On this fateful night, it was reported that eight of the most dangerous patients had escaped. Some were found hiding, some found dead, but three were never found at all. It's rumored that they still roam the halls, whether it's in spirit or human form is yet to be determined.

Just down the block is the Slaughterhouse. In 1974, legend has it that a gruesome murder was committed by one of its most dedicated employees, Homer Friesenhaun. Overworked and in the midst of a mental breakdown, he brutally butchered his niece and nephew when they came to visit him. He was then sent to the Psycho Asylum, but his ghost returned to the slaughter house—or maybe he's one of the three patients who escaped and was never found.
