I thought the nummygirl is registered to a different Mark Siever in Scottsdale, AZ.
As far as his mailbox being full and clients not being able to get their records, I know I would be completely overwhelmed and definitely clinically depressed if my spouse and anchor of my life had died in an accident. I can't imagine how he must feel knowing his best friend like a brother is involved in her violently brutal murder.
I have no idea if any of his family or TS siblings are helping him in any way with this.
We only know of a few people who've said they haven't been able to get their records, maybe there are many who have gotten theirs.
I'm not trying to be contrary, just thinking if it were me. I'm normally an extremely suspicious person and look to the spouse first, but in this case, I can see both sides.
