CSI: Miami Episode 9.07 On the Hook

We open on a man (mid-40's), Brad Webb, fishing on his own on a boat on the canal. We see an African American man Shane Newson, (20), standing dangerously on the bridge over the canal as if about to jump. As Brad is calling 911 shots come seemingly out of nowhere and shoot up Brad's boat, missing its target; Brad. The team investigates and learns shooter was hundreds of feet away. Walter finds the gun on a rooftop, and they bring it in to the lab. They bring Brad into protective custody, while they continue to figure out a motive as to who would try to kill him. While interviewing Shane it is clear he is anxious and paranoid, and is sure no one can help him. Through the lab work and DNA testing of the eye liquid found on the eyepiece of the rifle, they find a match; Dario Aquilar, third generation gang banger. Tripp gets a noise complaint from Shane's apartment and discovers Shane in the midst of pulling apart his apartment looking pointedly for specific items. Shane amidst his frenzy tells them he heard Brad on the phone when he was by the bridge, talking about "Vig" and nickels and dimes and numbers. The team soon discovers that Brad is a bookie and maybe someone who owed him money may have wanted him dead. While still in protective custody at MDPD shots from a distance aimed at Brad are fired. Walter and Ryan search the origin of the shots at the nearby train station platform and discover many of the items they saw Shane pulling from his apartment. Makings of a home made rifle. They bring Shane in and learn that he as well as Dario was, is terrified of talking. Tripp and Horatio review their files for commonalities and discover they both have the same parole officer, Neal Perkins. Neal also happened to be a client of Brads as was over his head in debt. Neal threatened to put Shane and Dario back into prison if they didn't follow through with his plan. Dario shot at Brad first, but Shane, growing a conscience, was there to distract him, to save Brad. Neal upset that Shane botched his plans to have Brad killed forces Shane to construct a homemade riffle and use it to kill Brad. Neal threatens the life of Shane's 18 year old cousin Tracy. Tracy, also under jurisdiction has been secretly raping her. Having enough evidence including a handwriting match from the gun instructions and other documents of Neal's, Horatio finds Neal and Tracy in a dilapidated trailer in the woods and stops him from hurting any further.
