Ledroit questions a sanitation worker about finding Edgar's bloodied t-shirt, as captured by a neighbourhood CCTV camera.

Gator hands Ledroit the missing footage of Marlon being beaten savagely by vice cop Nokes after he was discovered behind the club performing oral sex on Deputy Mayor Richard Costello.
