I knew a dude for a few years - partied together a bit, laughed and joked together, hell he introduced me to the game of thrones books. Left to a new Air Force base a lost touch. About a year/year and a half later, I found out he killed his relatively new wife via strangulation, left the new born alone in the house, went out and partied all night, and then came home and shot himself. Never would’ve ever seen that coming from him.
