Thousands of GI's smuggled them home. Che says the serial number is still visible on the rifle used to kill Keoki. Back at Hookman's room, we see him stamping another metal plate with Ookala's name on it. The scene switches to a wild shootout which brings numerous members of HPD and all the Five-O team except McGarrett, who is with the Governor. Duke wonders if this gunman is the killer of Keoki, but Danno doubts it.
Tear gas is used to flush out the gunman, who fires at the police and dies in a hail of bullets.
The gunman's rifle is an M-1. Suddenly it's revealed that Ookala, who is at the scene, has been shot and killed. Danno radios the governor's office, then McGarrett's car, suggesting that maybe the gunman was the sniper after all. McGarrett is disturbed when told of Ookala's death. After doing an autopsy on Ookala's body, Doc reveals that Ookala died from intestinal hemorrhaging, and the bullet passed down through his chest.
