John Tucker

John Tucker was a human who was stabbed by Suzie Costello with the life knife. The Cardiff police discovered the crime scene. When Torchwood Three arrived at the crime scene, he was brought back to life for a few moments using one of the Resurrection gauntlets held/operated by Suzie Costello. Unable to identify his attacker who approached him from behind and killed him with a single wound. He was scared and panicked in his two minutes of being brought back to life, when Jack Harkness asked him what he saw when he died he cried that there was only "nothing" after death.
