Carl Murphy was a human male who was employed at the Federation Embassy on Qo'noS from at least 2376 (KE novel: A Burning House) to 2379. Murphy worked at a large desk centered in the second floor hallway of the Embassy. It was his duty to handle all of Worf's in-embassy appointments.
In 2379, the Klingon group Klahb attempted to take over the embassy. When a steward named Kl'rt fired a Breen disruptor at Worf, Murphy immediately pressed the panic button on his desk, but it was disabled due to a dampening field. Kl'rt then turned and fired on Murphy, killing him just as Worf fired on Kl'rt.
