WHY wait until Tuesday to release new details? I doubt there could be much of significance, just the usual teasing by media, IMO.
I do believe everything points to SM except for the fact that they have no crime scene and no Heather. So what can they do? IMO, only relentless searching at this point, hopefully based on some knowledge of the (possible) POI and/or electronic data. If she is not found...this case is stalled permanently, unless someone comes forward with info, i.e something the POI said, did, etc. Even then, without finding her...I kind of despair at any justice or "closure" ( a ridiculous word, IMO).
I think the jeep incident is just ignorant nonsense and hope they are caught and charged as harshly as possible...even as to making terroristic threats.
