And the fat moron is now trying to put himself on the hook for the inevitable felony failure to pay child support. If the kid ends up on welfare, California is a state that comes after you for every dime, no matter where you are. They just let it rack up to about six figures, then lock you up until you pay. Or if you can't, you stay there. They don't fuck around. It is probably the absolute worst state in the country to get in trouble with child custody.
This is why he is an absolute moron. All he has to do to avoid this shit is stay home. At the very best, they'd have to spend months and tens of thousands of dollars trying to force him to get a DNA test, from across the country. Good luck.
