According to Jeffrey MacDonald's account of the night of February 16-17, 1970, the living room is where he struggled with four assailants and fought for his life, as well as the lives of his wife and children. If you've read about the Manson murders or seen the crime scene photos, you will notice furniture askew and, most importantly, not just the large areas of blood directly under the bodies but footprints, hand prints, castoff blood and spatter from the victims who attempted to escape. None of these things were found in the MacDonald living room despite this room being as cramped with furniture and items as the dining room.
MacDonald's reading glasses were found on the floor, directly underneath one of the windows. Both sides that go over the ears were found upright.
Blood was found in only two locations in the living room, both in very small quantities. The first location was a blood smear found on the cover of the Esquire magazine featuring an article on the Manson murders. The second was a speck of blood, typed as Kristen's, found on the outer lense of MacDonald's eyeglasses.
That is the sum total of the disarray to the living room.
Despite MacDonald alleging that one of the intruders tore his pajama top in a struggle on the sofa, not one pajama top fiber was found in any location in the living room.
Despite MacDonald claiming to have been struck with the club that beat both Colette and Kimberley, not one drop of their blood was found in the living room, either on the floor (from blood dripping from the weapon) or in cast-off marks on the walls.
Despite MacDonald claiming to have been struck with the club, no scrape marks were found on the living room ceiling.
Despite MacDonald's claims that his feet were bound up in the afghan when he fell off the sofa to the floor during the attack, the afghan was found on the sofa.
Quite a struggle.
