NL25 River Decision

[Mr_Pathetic]

This guy is generally nitty but not from the blinds. Not sure if he will bluff a missed draw on the river. So I guess my question is this: Even if I think that King may have hit him or that he may possibly bluff a missed draw should I still call here? I am guessing he has some kind of hand on flop and turn to keep calling, obviously looks like a draw but then river looks like a cheap bluff or a small pull me in bet.
