Vendetta

S14, E21: Andrew Donner was public enemy number one. He interfered with a foul ball during the championship series and that changed the outcome, as the team on its way to winning, ended up losing. Briscoe says you could start looking for his killer with the Manhattan phone book. He was killed by being hit over the head with a beer bottle in a dive bar. Very delicately, the bottle is reconstructed to get prints. In addition to the bartender, they get another set.
