The Cecil Hotel in Downtown Los Angeles (640 S. Main Street) is a budget hotel with 600 guest rooms (originally 700). Constructed by 1927, the hotel was intended for business travelers but in the 1950s it gained a reputation as a residence for transients. A portion of the hotel was refurbished in 2007 after new owners took over.
The Hotel is known for its criminal activity to include three murders and also several suicides. Most notably, the hotel was the reported residence for serial killers Richard Ramirez in 1985 and Jack Unterweger in 1991. Recently, in February 2013, the body of Elisa Lam, a 21-year-old Canadian woman, was found inside one of the water supply tanks on the hotel roof. The body was discovered after patrons complained of low water pressure.
Pauline Otten, 27, committed suicide by jumping out of a window of the Cecil Hotel in 1962, also killing an unlucky pedestrian when she landed on top of him.
Retired telephone operator Goldie Osgood, known as the Pershing Square Pigeon Lady, was raped and strangled at the Cecil in 1964. Her tiny room was ransacked; the killer was never found. In 1995, an escapee from the Peter Pitchess Honor Rancho was cornered and recaptured there.
To sum it up, the Hotel Cecil is very very haunted. There have been reports of full-bodied apparitions, blood curdling noises, cold spots, hot spots, scratching, strangling, and mists. People have not walked, ran from their rooms as they have been sleeping in the bed with ghosts. It's probably one of the most haunted places in all of Los Angeles.
