The Amityville Horror: Severed Pig's Head

When I was a kid, a friend of mine told me that a severed pig's head would appear in the fireplace and terrorize members of the Lutz family.  The Lutzes were the first people to move into the Defeo's old house and it was their experiences in the home that have been the basis for all Amityville Horror books and films.  My childhood friend informed me that the pig's head would show up (always in the fireplace), then speak and issue warnings to anyone who happened to be listening while, concurrently, the house walls would ooze "slime".  Having done research for these posts, I've found the claims of my elementary school compadre to have been mangled and in disarray.  
The Lutzes stated that their youngest daughter, Missy, had an imaginary friend in the form of an enormous pig named Jodie who spoke only to her.  They also claimed to witness a pair of glowing red animal eyes staring at them through the windows and found enormous hoof prints outside the house that were unexplained.  The fireplace bit came from another assertation by the Lutzes that husband and wife saw a demon's head appear to them in the fireplace and that the burnt image lingered on the wall after the fire had died.  

I think my old chum may have also been combining some bits from another infamous New York-based "occult" incident, the "Son of Sam" murders carried out by knucklehead David Berkowitz.  Berkowitz believed a dog spoke to him and instructed him on how and who to kill during his crime spree.  Satanism was an excuse for many shitheads in the '70s and '80s to kill groups of people willy-nilly and with care-free abandon.
