CSI: Miami Episode 7.06 Wrecking Crew

William Campbell, a prime witness who is about testify against big time gangster Joe Salucci, is murdered when a huge crane crashes into the high rise safe house that he's staying at. Campbell was going to testify that he was in a restroom stall at a club when he heard a murder take place and Joe Salucci's name was mentioned. It turns out that Joe's sixteen year old daughter recently died when an ATV accidentally ran her over while at a bonfire on the beach.

Joe sought revenge by having one of his men track down and kill the ATV driver at the club but the body was never recovered. Things get even more complicated when it's discovered that the person who remotely operated the crane that killed Campbell was none other than his seventeen year old son Noah Campbell. Angry about having to leave his friends and his life for the Witness Protection Program, Noah wanted to scare his dad into not testifying so he figured out, via the internet, how to operate a crane. However, he didn't expect things to go terribly wrong. In the end, Horatio is able to track down the body of our ATV driver, who was shot in the knee but not killed by Salucci's men and then transported to the beach where Salucci finished him off and buried him.
