Bloemker

Ensign Bloemker was a Starfleet security officer assigned to the USS Enterprise-A sometime following the whale probe incident. She was part of a landing party assigned to investigate the destruction of a Federation colony on Omicron Ceti IV by a renegade Starfleet vessel. During this mission, Bloemker was killed by the fugitive Garth of Izar, who used his telepathic abilities to assume her identity and masquerade as her aboard the Enterprise. The ruse was part of an effort by Garth to assassinate Captain James T. Kirk, who had disgraced Garth several years earlier. During a telepathically-induced, shipwide hallucination of Dante's Inferno, Kirk sees Bloemker's body encased in ice in the ninth circle of Hell; this served as a foreshadowing of Bloemker's "betrayal" of the crew as she had been replaced by Garth. Garth later assumed Ensign Bearclaw's identity for the failed murder attempt against Kirk. Bloemker's naked body was found later amongst the ruins of the Omicron Ceti colony by Federation investigators, led by Finnegan. Finnegan uncovered Garth's deception when he recognized his disguise as that of the dead ensign, and was incapacitated by Garth who proceeded to assume his identity. Kirk later confronted Garth as Finnegan, and was able to apprehend him.
