By the way, I don't know who the killer is, but man he is a crack shot! He made a homemade pistol grip shotgun with about a 14" barrel and not only got it to work, but fired both barrels and managed to hit Abe in the chest from about 30 feet away. I don't know if he was shooting from the hip, but that's about the only way to fire those things, even though it's almost impossible to aim that way. But that's practically an impossible shot, and he pulled it off under pressure.
I'm not praising an act of murder, but whoever this guy is, he is a highly skilled shooter, to put it mildly.
