Payback

S14, E12: Jerry Tortino, a part-time buggy driver, is found shot to death with a crescent moon branded on his neck at the West Side stables. Jerry was a former bookie who served two out of a ten-year sentence in Sing Sing and he got off easy because he ratted out a major crime boss, Federico Righetti. Three weeks after Righetti gets out of prison, Tortino is killed. Briscoe and Green talk to Righetti's nephew Peter, which doesn't get them very far. Nonetheless, there's a connection they find between the Righetti's and Tortino. It seems they share the same real estate agent, Cary Stillwell.
