Yes,clearly some jiggery-pokery there alright.
Yes clearly their was, however I do not go along with the theory that AP had anything to do with the murders. IMO the AP rifle was at the house on that night, and was removed by the family.
AP used different ammo than was used at the farm [hollow point]. It has always seemed strange to me that not all bullets were fragmented when hollow point is designed to fragment suggesting that different ammo was used during the murders.
