sister-in-law posted on facebook about the same time as all of this started an allegiance to isis. anticipate there's been some suggestion that maybe she was in some way influencing your brother. >> we didn't know she had any kind of relations with isis or anything like that. if you met her, she was like the girl next door, you know? sweet, innocent, kind. the kient thnd that's always sm nice to you. you would never, ever guess that that girl would have ties to isis. >> did she ever express any unhappiness or did you ever have any conversations about being muslim in america, or terrorism? or did you talkn't a the paris attacks? >> no, actually not at all. i mean, being a housewife, we don't talk about paris attacks and this and that in front of your kid, to be honest. political agenda is not something we discuss in front of our kids.
