Creep factor: At least six people have committed suicide here. In 1944, 19-year-old Dorothy Jean Purcell threw her newborn baby boy out the window; American serial killer Richard Ramirez, and Austrian serial killer Jack Unterweger, both lived in the hotel at different times during their killing sprees. Elizabeth Short, known as the “Black Dahlia,” reportedly stayed at the hotel right before her unsolved murder in 1947.
The most famous case now is of Elisa Lam in 2013, a Canadian tourist whose naked corpse was found in the hotel's rooftop water tank (people had been showering in and drinking that same water). Her death remains one of the biggest puzzles; with CCTV footage showing Lam behaving erratically in the elevator right before her death, many were convinced of the hotel being haunted, and made eerie connections between Lam's death and the Black Dahlia's. The last reported suicide in the hotel was of a man in 2015. BuzzFeed Unsolved: True Crime covered it in season 1, episode 3, which you can watch here.
There have been sightings of a young boy's ghost on the fourth floor, as well as loud thumps on the walls, and strange smells. The hotel's tragic history served as inspiration for season five of American Horror Story. The violence of the hotel is so bizarre that Wikipedia has a whole separate page dedicated to a list of all the murders and occurrences.
Status: The hotel is no longer in operation and visitors are not allowed. It is currently undergoing extensive renovation to become a mix of boutique hotel rooms and small apartments.
