definitely makes me think it's misdirection of some sort. i can't imagine there suddenly being a massive shootout. i'm kinda thinking he does something to make himself the super villain to the cops and clear the fam...the ricin's himself. if he just disappears they will always have his family under surveillance until he turns up. if he does something that appears drastic, with a big gun, then offs himself he could potentially leave them the money and they could be set for life.
