Here's the account they cite:
Douglas Harrison, 42 of Memphis, was arrested in connection with a series of dead bodies found in a freezer located in his shed. According to reports, the bodies were dressed in clown costumes with clown makeup on the faces.
The Memphis Coroners office made a gruesome discovery today after several 911 calls were placed by neighbors regarding their concern of suspicious activity at the residence of Harrison. At approximately 8 p.m., police were dispatched to Walnut Street and Polk Ave. Upon their arrival, authorities were met by a group of residents at the corner where they assisted police in locating the home in question. Police proceeded to the 800 Block of Polk Ave where they located the home. Authorities knocked on the door of the residence and was met by a male, dressed in a Clown costume, who appeared to be in his late 30’s to early 40’s and seemed to be under the influence of drugs.
Upon entering the home, authorities indicated that the home “smelled of cotton candy and death”. The inside of the home was covered wall to wall with circus decorations and the sound of circus music could be heard throughout the home.
So this goes much further than threats. And it scales up from an individual victim to a series, linking clowns to serial killers. The dead are forced into clown costumes. And there's the specter of clown sex.
