The Joker, using the amulet of Apophis, takes full control of Green Lantern Alan Scott, and uses his body to kill Alan’s Justice Society of America teammate, Sandman, by stabbing him in the gut with a knife construct. Carrying Sandman’s corpse while flying, the Joker learns that a Green Lantern ring needs to be recharged as Alan’s ring ran out of power mid-flight, plunging him into his death.
Edit: We later learn on the next issues that Green Lantern Alan Scott survived his fall but is grievously injured.
