Today's news (9/14/17): Sheriff clears the fire chief/husband in Nanette's death:

I'm not suggesting that the husband is in any way involved, but it's not often I see LE outright clear someone. (I'm sure it happens, I just don't see it often.)
I've seen many cases where LE will state that a person is "not a suspect" (and more often than not, a totally different person is arrested), but "cleared" is much bolder statement, IMO. I wonder what compelling evidence they have that proves he had nothing to do with this.
I hope Nanette's loved ones find justice.
