A newly promoted Starfleet lieutenant and pilot of the Defiant, celebrated for his skill in battle, whose unexplained shooting in his own quarters begins Ezri Dax's hunt for a killer.
Hector Ilario appears in Field of Fire, played by Art Chudabala.
In 2375 the young lieutenant is the toast of Deep Space 9 after flying the Defiant through an engagement in which several Jem'Hadar ships are destroyed. He drinks rather too much at the party in his honour, and Ezri Dax walks him back to his quarters. The next morning he is found dead there, killed at close range by a projectile weapon although no one else entered the room.
The weapon proves to be a TR-116 rifle fitted with a micro-transporter that beams the bullet to its target. Two more officers die in the same way before Ezri, drawing on the memories of the murderer Joran Dax, identifies the Vulcan officer Chu'lak as the killer.
