24: Day 3: 6:00AM-7:00AM (2004) [Kathy McCartney]: Possibly dies (off-screen) of the exotic virus after the terrorists introduce it into the hotel’s ventilation system. She does not show any symptoms when we last see her, but since it’s been suggested and considering the virus’ mortality rate, I’ll go ahead and list it. (Thanks to PortsGuy)
