I don’t think Alex was alone when his wife and kid were killed. Alex may not have done it but he was surely there.
Why?
2 guns 300 blackout and 12 guage.
2 kinds of 12 guage ammo. Buck shot and bird shot.
It looks like an experienced killer. A shot to the gut to bowl them over then a shot to the top of the head to finish them. Classic teamwork.
The more I listen to the testimony the more I lean toward Alex got sideways with the drug cartel and they set him up real good.
My other theory is that Paul and or Maggie hid his oxy pills that evening and he went psycho because he needed his fix and got into a row with them down at the kennels and then in a rage shot them. But to me if it was an argument turned deadly he’d be more likely to just grab a gun and shoot them not two guns and three types of ammo. That takes some thought.
Have you never loaded your shotgun like that? It is how I do it, birdshot followed by slugs actually. Times 3, 6 total shells, maximum damage.
