Batman #620 Newsstand

BROKEN CITY PART 1 Batman is trying to get information from Killer Croc about Elizabeth Lupo's death. He does so by hanging Croc upside down from the side of a building. Batman punches Croc repeatedly. He knows that Croc killed Lupo. He also knows he has no evidence to prove it. What he doesn't know is who hired Croc. Batman searches Angel Lupo's place and finds a woman named Margo Farr, half-dressed, in bed. She tells him that Angel hired Croc to kill his sister. Batman tricks Margo into revealing that Angel has fled to Havana, Cuba. He then waits outside and follows her, because he believes Angel is not really in Havana. While following Margo, Batman saves her from a street punk.
