Damir Gorjanc was a Human male who was employed at the Federation Embassy on Qo'noS in the 24th century. Gorjanc often relayed messages to Ambassador Worf through the embassy's communications systems.
In 2379, the Klingon group Klahb attempted to take over the embassy. While in captivity, Gorjanc told Rov, the leader of the group, that they would never get away with their crimes. In response, Rov killed him with a disruptor blast.
Following the attack, Worf was recalled to Earth and among other things, he personally conveyed his condolences to Gorjanc's family. (TNG novel: A Time for War, A Time for Peace)
