This episode appears to be based on the 1991 Anthony Riggs case. In March 1991, Army Specialist Anthony Riggs was shot to death in Detroit shortly after his return from the Persian Gulf War. It was later revealed he had been shot by his wife, Toni Cato Riggs, so that she could collect his life insurance.
Chris Noth (Detective Mike Logan) and Dominic Chianese (Judge Paul Kaylin) went on to work together in five episodes of The Good Wife (2009) portraying the characters Peter Florrick and Judge Michael Marx respectively.
