According to the plot, how did rich New Yorker Bart Bass, Chuck's estranged father, die?

Because Bart's fake death was deemed insufficiently tragic, Gossip Girl created a second death for him involving none other than his son Chuck. In the last encounter between the two in Season 6, a physical altercation occurs on a roof building causing Bart to fall off while attempting to lunge at Chuck.
