Lisanne Hexter was a female human in the 24th century, and by 2376 was the warden in charge of the top-secret prison facility Ananke Alpha. She had a reputation for not cooperating when asked about happenings at the facility and security had become especially tight since the Female Changeling became its sole prisoner.
After the Jem'Hadar Taran'atar attacked Captain Kira Nerys and Lieutenant Ro Laren for no apparent reason, Commander Elias Vaughn contacted Lisanne Hexter with the hopes of examining tape recordings of his discussion with the female changeling when he had visited her the week before. Hexter was unexpectedly forthcoming and sent the video to Vaughn on Deep Space 9. (DS9 novel: Warpath)
