After being called by Edgar on top of a roof, Halloran instructs everyone to shoot the remote and not go for a fatal shot. Edgar presses the remote, and someone shoots Edgar in the chest. After Edgar is taken to the hospital, a body appears on the bridge in the park.


Halloran's sliced head.

After being abducted and put into the laser room with Logan, Halloran started yelling at John's voice telling them to confess or die. Halloran offers to go first but then pushes Logan's button. Logan confesses to mislabeling John's x-rays, but appears to be killed by the laser collar. Halloran then goes and confesses to letting criminals go free, and admitting that innocent people died because of him. He then notices that there were no marks on the ceiling on the other side of the room, revealing that Logan's lasers were less powerful, and Logan rises up and reveals to Halloran that he was the one running the game. Confused Halloran demanded an explanation. Logan revealed the long desiccated corpses of Anna and Ryan saying that he participated in the same game they had a decade ago. also mentioning that Eleanor will provide his alibi. Logan declares how so many innocent people ended up on his table because of Halloran and that he will now speak for the lives ruined by such individuals. He then activates Halloran's lasers and slices his head into pieces before sealing his tomb with the words "I speak for the dead".


Halloran is nothing less of a greedy and corrupt detective who will do anything in order to survive, evident when he pushed Logan's button first in their game despite him volunteering to go first which he then tried to win Logan's trust after learning he failed his game in order to bargain for his life. His cunning personality echoed many times throughout the film, such as when he allowed many murderers and rapists to walk free so he could use them as criminal informants.


  • The weapon used is Glock 17
  • Although Logan is revealed to be the Jigsaw killer, Halloran still serves as the main antagonist due to his actions having impacted and eventually leading to Logan to replicate Jigsaw's first game. Overall it was Halloran's actions that had the most impact as they caused the events of the film.
