Jack has a hard time accepting that his brother committed suicide. So he started looking at his brother's dead. Sean was a cop and Jack believed that his brother might have committed suicide because of his last case.
A woman was killed and cut in two. That's the case his brother was working on before his death. And on the day he died, he had an appointment with an informer.
Who is this informer? Going to find out soon.
