The Sunrise Hills Shopping Mall

This is the location that was chosen by Ivan Erwic to test the Sentox Nerve Gas and it's effects as revenge for Walt Cummings and James Nathanson's betrayal. After an operation led by Jack Bauer to get close to Erwic fell through, Bauer himself staged an undercover operation to get the Sentox. The plan was to pose as a programmer, and reprogram a detonation device with a CTU tracker on it. After he did this, the terrorists kidnapped him, leading him to the Sunrise Hills Mall where the canister would be set off. Upon arrival, they all disguised themselves as maintenance men. Then they killed a gaurd so that they could gain access to the ventilation system. When the terrorists asked Bauer for the arming codes, CTU ordered Bauer to give them the code "Alpha Kilo Charlie". After no response from Bauer, the code was repeated to him, where he said, "Echo Bravo Charlie". When the terrorists started to realize this was incorrect, they knocked Jack out, dragging him into the next room and using the dead gaurds cuffs to secure him. Once Jack regained conciousness, he realized that the terrorists had figured out another way to release the gas. Just as a terrorist was about to murder him, Bauer killed him and took his mask, uncuffed himself, and attempted to stop the gas. Although he managed to stop the flow of the gas, he wasn't able to prevent some of it flowing into the system. After realizing the terrorist still had the device to be tracked, he broke persuit to save civilian lives. During this attack, 11 people were killed before CTU could secure and lock down the area.
