Why would you characterize an obvious, distraught Mother as "pitching a fit?" And Police Chief let momma read a statement.
Please be reminded this is a serious situation about a young mother that's gone missing without a trace.
In other cases, such as the recent high-profile case in Colorado, the police issued a press release early on, sent it out to the media and basically invited the media to show up at the SO's house and start asking questions.
This case is different. Here the police did a welfare check on 12/2, didn't find anything suspicious, likely spoke to PF, called the FBI and the CBI, and never issued a press release. They acted, IMO, like it was a probably suicide or an adult who just decided to go away for awhile.
It appears from the Missing Mother facebook pages that the media became aware of the disappearance because KB's family notified them and begged them to run the story. (That is my take.) The story blew up on a slow news weekend, suddenly was picked up by national media, and the media started to call WPPD, wondering why hadn't they said anything about this, issued a press release, etc. So WPPD scheduled a press release.
Does that mean that this case is not serious? No, it does not mean that. But there are people who disappear or commit suicide every day who don't get any publicity.
When I suggested, "mother pitched a fit," (and this is clearly speculation, as I would imagine what I would do if my daughter disappeared and it didn't look like anyone was investigating) she was certainly justified in doing so, and in getting the news media to pay attention.
