Jo Nakashima

Joana Nakashima was a freelance journalist. She investigated ATMOS and infiltrated the Rattigan Academy. She was discovered and was brutally thrown out from the academy. While driving back to London, she tried to get in touch with UNIT, but she could only reach an answering machine.

Suddenly the ATMOS took control over the car and drove into the river, thus killing Jo. (DW: The Sontaran Stratagem)
