Jo Nakashima

Joana 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 she 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. She again tried to leave, but it locked the doors, trapping her. Jo kept on trying to stop the car. It kept on moving. Jo let out a scream and it drove into the river, drowning her. (DW: The Sontaran Stratagem)
