I knew he died in '04 after submitting the manuscripts for the whole trilogy to his publisher, but I wasn't sure when the first book was published. If there was any correlation between the two events, it may have well gone the other way and Larsson thought of it first. Perhaps he was the inspiration for the other guy. Absent a death-bed confession from that guy, about as likely as hell freezing over, we'll never know. Fun to speculate, though, because of the similarities with regard to both plot and timing.
