Chaplain Tony Dickey
I wouldn't classify Chaplain Tony Dickey as a family spokesperson. He's been helping them, and he speaks to the media. He hasn't been hired as a spokesperson.
LE
Mobile LE is technically the department searching for Brittney. The poster earlier described their typical approach to missing adult drug users, and that is pretty much what has been said in this case. But they claim to be looking for her. Baldwin County is in charge of the sex abuse investigation, and to the extent that her disappearance may be related to their case, they will also look for her.
DH Suicide
I believe the reference on HLN to a shotgun being used was a mistake. It was a handgun. I don't know guns, but I believe it was a 25 (is that even a type of gun?)
CW
She hears LE say they think BW is hiding, and she clings to it. She wants her daughter to be safe. She did know about the investigation of DH on sex abuse charges, but she must not have believed it was true. I really don't know how she formulated her opinions.
My Thoughts
I hope that LE is withholding information due to the highly unusual circumstances of the case. They have multiple family members involved in a slew of crimes, so they have to figure everything out and learn who can be trusted. I know there are people considered suspects who are not family members. As long as LE is gathering evidence and until they know for certain, they aren't going to publicly accuse anyone of involvement in BW's disappearance. Likewise, the chaplain isn't going to accuse either. They met with LE today, so they have a little more understanding of what's going on.
