Tbh I've been thinking he killed his own dad for a minute. It's also important to not that the zombies in this story are not your typical zombies. It's not a you get bitten you get infected kind of thing & it is never mentioned that they're dangerous. Only that it unnerved people to the point of causing hysteria plus the natural disasters made it worse. I'm thinking that either his dad dies of an injury or kills himself, turns into a zombie & guwon lived with the body/zombie, went crazy, and "killed" him.
