western intelligence believe she's played more of a logistical, fund-raising role for al shabab in the region rather than a front line fighting role. >> what do we know about her last known whereabouts? >> what we know about her last known whereabouts is late 2011, there was a raid on a safe house in mombasa on the kenyan coast and she managed to evade capture. they didn't get her. one of her associates was arrested and he's now on trial for a plot in late 2011 to attack a nairobi shopping mall and also hotels in mumbasa. >> how much stock do investigators put into this claim for the al shabab twitter account denying that any women were involved in the kenya attack? it's a twitter account and who knows if they're telling the truth? >> well, this is the very same twitter account which released an audio statement from the leader of al shabab last night. mukhtar abu zubeyr.
