CSI: Miami Season 5 Episode 21

The mother and father of all nasty divorce cases where the couple's house is divided by lasers and the wife cuts the pleasure boat in half with a chainsaw in the very first scene (while screaming hubby blasts warning shots with a shotgun from his end) leads to a murder investigation when the husband's girlfriend-on-the-side is found killed inside the house. But wait, there's more ... the guy who bought the husband's Lamborghini for 200 bucks (from the wife) is found murdered with his neck slammed in the door, and both divorce lawyers display incredibly greedy streaks which cause them to plumb the depths of unethical behavior.
