This is a family-killer that I don't think the cops are going to take alive because he's killed his ex-wife, the grandmother and great-grandmother of his kids, and a sister-in-law, brother-in-law, and niece. He's prowling my neck of the woods, and schools and stuff have been locked down here and there. I don't think he's looking to shoot those up, Lanza-style, though.
He seems to have killed his ex based on a dispute over custody. Because, really, what in the world is going to prove you deserve custody of some kids like killing their mom?
I don't understand why pulling a gun on numerous former relatives seemed like the way to fix this guy's problems to him-- but for some crazy reason I feel like he probably visited an MRA site or two. I could be wrong. I almost hope I am.
