S02:E211 - Jewler's Wife

The wife of a successful jeweler is found in their home, stripped naked and beaten to death. The jeweler immediately falls under suspicion, but he's not alone. The couple had been overseeing expensive renovations to their home for the past year - meaning literally hundreds of people had access to the house before the murder. This was a horrible crime with a multitude of suspects. But the jeweler's wife was no sitting duck - she had fought back. And under her fingernails is the DNA that will lead detectives to her killer.
