In the 2004-05 limited series "Identity Crisis", Jean Loring kills Sue Dibny, the wife of the Elongated Man. After stealing some of the Atom's shrinking technology and his costume, she kills Sue in a misguided attempt to win Palmer back. She also arranges a hit on Tim Drake's father which is carried out by Captain Boomerang (Digger Harkness). The intent is for Jack Drake to kill some random attacker, but both manage to kill each other. After committing her to Arkham Asylum, Palmer shrinks himself to microscopic size and disappears.
