Jo Nakashima

Johanna Nakashima was a freelance journalist. She investigated ATMOS and infiltrated the Rattigan Academy. She was discovered and was thrown out of the academy. While driving back to London, she tried to get in touch with UNIT, but could only reach an answering machine. Her car stopped at the river saying, "This is your final destination." She tried to leave.

Suddenly, the ATMOS took control of the car and began to roll into the river. It locked the doors, trapping her, and kept on moving. Jo let out a scream as it drove into the river, where it sank with her inside. (TV: The Sontaran Stratagem)
