Luiz Sifuentes was a New York City resident who witnessed the murder of a person in Central Park. When he approached the body of a man who had been shot, he picked up the revolver used as the murder weapon. When he saw Daredevil approaching the scene, he fled, but was tackled by the vigilante and left tied in a tree for the police.
Sifuente's case was assigned to Matt Murdock, Daredevil's alter-ego, who defended him in the court. Using his radar sense to detect whether Sifuentes was lying on his history or not, Murdock discovered that Sifuentes was indeed innocent. As Daredevil, Murdock tracked down the people who had shot the man in Central Park and managed to prove Sifuente's innocence.
