I agree the flash bangs were telling and yes the Sheriff's office said it was for safety and based on information they had prior to serving the warrant (which I assumed was that he owned a gun and maybe that there was at least one other person in the house, MOO: plus I am guessing that they have evidence that he would have good reason to panic... such as they have evidence tying him to her car like footage that he brought it there).
However, the person of interest does NOT have a criminal record, per the Q13 Fox TV video posted by
@Gardenista yesterday in which they also revealed that LE doesn't know where the POI is (which btw, I sure hope that not knowing his location was a ruse or that they have found him by now).
"no criminal history" Search continue for missing Pierce County woman more than a week after disappearance
@spiritseeker31 there is a map update based on latest news reports, searchers found a possible witness that could help put together timeline and it was a local resident in the search area near Lincoln Park in Tacoma.
This story is heartbreaking. The poor mother (and expectant grandmother) "I want my miracle". My heart aches for her.
