The Bitter End

Vinny and Jamie answer a call that leads them to the Bitterman housing project, where Vinny grew up and which the locals call "The Bitter End." A young woman who wants out of gang life commits suicide in front of Jamie and Vinny, killing herself and her infant son. Danny feels responsible, as he told the woman and her sister almost 13 years ago, after their parents were killed, that he'd protect them. Meanwhile, Santana (Kamar de los Reyes), leader of the Los Lordes gang that terrorizes The Bitter End, declares war on the department, later killing Vinny in an ambush attack. Concurrently, Frank butts heads with Erin and the D.A. over their unofficial policy of dropping cases involving residents of the Bitterman project when witnesses choose not to testify.
