Forgot one and the one that makes me speculate more than the others.
It’s not known whether Betts targeted his 22-year-old sister, Megan. They had spent an hour together at a bar in the same area before the shooting.
A few posts back after learning his sister was one of the victims I wondered if this was an Honor Killing gone nuclear.
Or another more likely possibility
Maybe she knew what was going on and maybe she was trying to talk him out of it.
