Lindsey Purviance

Lieutenant Lindsey Purviance was a Starfleet officer during the 23rd century.

In 2275, Purviance was assigned to Space Station Sigma One when he was killed by an Orion agent. The agent then assumed Purviance's identity and used it to infiltrate the USS Enterprise (NCC-1701) in search of the trans-shield anode. In his search, the Orion killed several members of the crew and was responsible for acts of terrorism aboard the starship before he was finally stopped by Lieutenant Pavel Chekov.
