Catwoman (1993 2nd Series) #24 DC (374590695)

Hector Marquez confronts his two sons, furious that they had spent so much time and energy on hunting down a petty thief like Catwoman and plans to usurp his authority. Unexpectedly, Hillary Hellman then emerges from the shadows, looking to kill Paulo for sending an assassin after her previously. Each party has the other at a stalemate, and in exasperation, Hector frees Catwoman and orders her away, deeming her an outsider who has no place in a family squabble. Catwoman, determined to not leave empty-handed, stays behind and tries to extort both of Hector's sons, only to be rebuffed by both. Not long after, the brothers find Hillary trying to make off with the family's money; an enraged Paulo tries to kill her, but Eduardo is still in love with Hillary, and tries to protect her. The brothers end up killing each other, leaving Catwoman to confront Hillary and Hector Marquez. Hector reveals that the Hellmans and the Marquezes were once one family - he is in fact Bryce Hellman's brother, and spent most of his early life trying to outdo Bryce, only to spend his later years trying to patch the family back together. A tearful Hillary tries to reconcile with her uncle, but Hector, knowing of her treachery and realizing that his family is beyond repair, kills her. He then gives Catwoman the Marquez Dagger, stating that the Marquez name is no longer worth anything. As Catwoman leaves, Hector activates a series of explosives planted in the house, ending the Marquez/Hellman line once and for all.
