2x4 - Cold Squad

While Ali and Logozzo investigate the murder of retired teacher Merv Doucette, they are surprised to learn that, after a stroke, Doucette's behavior had changed drastically, and he'd gone from being a mild-mannered school teacher to a sex fiend who went to swinger parties. His wife, also a teacher, just happened to teach at Radford, where Jackie had gone to school. While Eddie tries to figure out how much money Jackie's family must have had to send her to Radford, which Logozzo estimates costs in the neighborhood of $30,000 a year, Jackie helps Ali question the widow after they realise that the prime suspect, Donnie Coombs, works for her, and came into a windfall the day after the insurance payout on Merv's life.
