Stardate: unknown Station log: Kira, Bashir, Dax, O’Brien, and some others are toasting recent arrival Lieutenant Hector Ilario, who has been doing some superb piloting of the Defiant. Later, Dax escorts a spectacularly drunk Ilario back to his cabin, where he shows her a picture of him laughing with two of his Academy classmates and flirts with her a bit before she heads back to her own cabin. The next morning, she awakens to a commotion: Ilario has been shot and killed at close range with a tritanium bullet. Sisko recognizes the bullet as belonging to a TR-116, a Starfleet prototype that was basically a modern take on an old-fashioned rifle. Starfleet abandoned the TR-116s, but a Starfleet officer could have access to the replicator pattern. Chemically powered projectile weapons leave powder burns when fired at close range, but there are no signs of such residue on Ilario’s body.
