Joseph Carey

Lieutenant Joseph Carey was a Starfleet officer in the 24th century, assigned as the assistant chief engineer of USS Voyager in 2371. He had a wife and two sons.

In an alternate timeline while Voyager'' was still in drydock, Carey was working in Engineering when he met Seven of Nine, who had been sent back in time by Captain Braxton. Carey tried to engage in small talk, getting to know the new crew, saying they should have lunch sometime, but Seven excused herself by saying she was temporarily assigned to Voyager from Utopia Planitia. Later, while Captain Janeway and Admiral Patterson were conducting their initial tour of Engineering, a malfunction crept up in the EPS conduits. Carey commented he'd run a diagnostic on those systems that morning, and offered to fix it, but Janeway noted that she wanted an opportunity to get her hands dirty. (VOY: "Relativity")''

After the death of his department head, Carey became the acting chief engineer. (VOY: "Caretaker")

Carey was to be selected as the new chief engineer, until former Maquis member B'Elanna Torres was selected instead by Captain Janeway. Carey and B'Elanna's work relationship was conflicting at first, leading to a fight. They eventually set aside their differences, and, although initially disappointed in the decision, Carey came to respect Torres' expertise. (VOY: "Parallax")

Months after being stranded in the Delta Quadrant, Tuvok discovered that someone onboard Voyager had secretly given Starfleet technology to the Kazon. To hide her tracks, Seska tried to frame Lieutenant Carey. During the investigation, Carey was confined to quarters. (VOY: "State of Flux")

''In an alternate timeline, Carey was killed during the so-called "Year of Hell" conflict with the Krenim. (VOY: "Before and After")''

In 2377, Carey was killed on the planet Uxal while searching for fragments on the Friendship 1 probe, which had irradiated the planet's inhabitants with antimatter radiation. Carey was shot by Verin, who had taken the Voyager away team hostage, demanding that Captain Kathryn Janeway relocate his people to another planet. He was beamed back to Voyager, but arrived in Sickbay dead, having been shot through the heart. After his death, it was discovered he had been building a 'ship in a bottle' model of Voyager. There was only one nacelle left unfinished. (VOY: "Friendship One").

Background
Carey was played by Josh Clark. Clark had previously played an unnamed conn crewman in TNG: "Justice." Even though the two roles were many years apart, Clark is very recognizable, so it seems as though Carey may have served on the Enterprise-D earlier in his career.
