In their own place with the little girl.
I'm surprised the widow hasn't been charged. She had to have known what they were doing. Maybe in her mind it was okay since the Quran commands to kill infidels. I've read comments though that she could have been shooed out of the room as they built bombs but you can't pee on my leg and tell me it's raining.
In my book she's guilty of withholding info which resulted in four deaths.
