Up on the Roof

Martinez works his first case, which involves a fake ATM. A foster child that Fancy and his wife had been caring for is ordered back into the custody of his real mother who's just been released from a detox program. Sipowicz and Kelly investigate a mob shooting that turns up the notebook that Marino kept Janice's name in. Later the triggerman who nailed Giardella, and that Laura can identify, is trapped on a roof with a hostage.
