John Wayne Gacy postcard threatening his attorney just month's after he was sentenced to death. Gacy has written his attorney's name and address on the front which is postmarked June 6, 1980.
 
Gacy writes, "GARBAGE MOUTH: BOOKS AND MOVIES?!  I want you to defend me when I slowly kill your wop bastard kids temporary insanity!  Try and screw the whore you live with.  She will have a red hot poker in her a** when you get home."
