The shooter was stationed inside the house and immediately began firing with an AR-15-style rifle, Barker said.
Investigators also discovered a black lab shot dead in the basement of the house that belonged to the ex-girlfriend of the shooter.
[The ex girlfriend] also told investigators that she believed Ruth had set her pick-up truck on fire while it was sitting in the home’s driveway in August, according to an affidavit.
A rational observation.
I too, wish we could ascertain who was going to snap and do bad things before they have to do something crazy enough to be lawfully convicted, but there’s gotta be a process.
