Three night club owners are killed within six weeks of each other. All killed with the same gun. The sixth killing comes on the same day as the anniversary of Lt. Beaumont accidently killing a 14 year-old-boy. The Knights discover a garbage collector is behind the killings. Beaumont is setup as a silent partner of a new club. When the collector pushes her take his offer, she says she has a better deal. Unfortunately she uses the phrase ""Case closed, cerrado,"" that she also used at a news conference earlier in the week and is recognized as a cop. She is grabbed and forced into the alley. There she wrestles free, but is lured into a similar dark alley as when she killed the teenage boy. She kills the collector as he comes up behind Joe at the end of the alley.
