The gig, education? I think the Weisenthal Center will keep that up for awhile. Catching barbarians like the doctor, I suppose that gig will end soon. As to tipping off "your suspect", there is no identified suspect, only a region near a family member where he's thought to be living. Thus the need for further information.
The suspect would know who he is, so if they point out a region they think he might be in, it would give him the opportunity to hide or move. At least in my view. Of course if the guy is so old and does not even care about running, this could help track him down.
