Ensign Carr was a male Starfleet security officer serving aboard the USS Enterprise-E in 2381.
During the Borg Invasion of 2381, Carr was aboard the Enterprise when it and the USS Aventine passed through a subspace tunnel, ending up near the Carina Arm near the meridian of the Delta and Gamma Quadrants. The vessels were boarded by Hirogen hunters, and Carr was assigned to the Bridge to protect the command crew. As the Alpha Hirogen approached, power went out aboard the Bridge, and in the darkness two flash grenades were detonated. Carr was killed by the Hirogen hunters, his throat slit.
