Police came up with idea that semi-automatic rifle went off second time (recoil)
Everyone should pause for a moment and think about this, because what we have here is a situation where police officers at the scene (whilst the bodies are still insitu) gathered around the body of Sheila in the main bedroom, debating amongst themselves how Sheila could have shot herself a second time? They came to the conclusion that it was possible for her to have done so by a process of recoil, where the weapon had discharged itself a second time within a split second of the first shot having gone off?
According to them, it was only possible for this to happen involving use of semi-automatic firearms...
