Shannon

Shannon is an administrator at UNATCO Headquarters at Liberty Island. She steals weapons from the armory and, with cooperation of Kaplan, sells them on the streets. Their hiding place is beneath the floor in Alex Jacobson's office. She reveals that to JC Denton when he's escaping from UNATCO and offers him 3 scrambler grenades, 1250 credits each.

Shannon is finally caught shortly afterwards, thanks to Simons' involvement.
