Don't know about TH's parents being interviewed or not.
Not worried about no arrest yet made.
We have our own feelings about what happened (to K).
What is your theory?
DY: That K is alive and someone is holding him.. don't know where, how many, etc.
KH: we dont' know where he is, that's why we need to keep looking.
DY" we dont have any evidence to show he's not alive, that's a big deal.
