She was later posted on the same space station as one of her sisters. She found this difficult and used it as an example of why she had to keep her personal and her professional lives separate. Two sisters of hers were teachers.
Cusak was later given command of the USS Olympia. The ship left the Federation in 2363 on a mission to explore the Beta Quadrant. In 2371, when the ship was returning home, they discovered a planet surrounded by an energy barrier in the Rutharian sector. When the Olympia scanned the planet, the ship was hit by a surge of metreon radiation which disabled its warp core and caused the ship to crash. Cusak was the only survivor.
When she attempted to send a distress call, the metreon radiation sent the message three years into the future where she talked with crew members of the USS Defiant. When the Defiant arrived at the planet in 2374, they discovered that she had been dead for three years. Her body was taken back to Deep Space 9, where the crew held a wake. Despite not having met her, the crew believed she had made a real difference to their lives just through "the sweet sound of her voice." (DS9 episode: "The Sound of Her Voice")
Captain Cusak's death had a lasting affect on the crew, particularly on Captain Benjamin Sisko. Commander Arla Rees had read the report on the crew's encounter with Cusak when she was assigned to Deep Space 9 around the same time. (DS9 - Millennium novel: The Fall of Terok Nor)
