Crewman Boyce was a member of the Starfleet personnel, assigned to Deep Space 9, serving under Captain Benjamin Sisko.
In 2372, Boyce was killed on the bridge of the USS Defiant during an attack by two Jem'Hadar fighters in the atmosphere of a gas giant in the Gamma Quadrant. (DS9: "Starship Down")
This was a homage to Phil Boyce from TOS: "The Cage". (Star Trek Encyclopedia, 4th ed., vol. 1, p. 99)
