CP,
I'm not a state resident such as yourself, but I share in some of your frustration. I wish she'd be found, as with all other missing individuals. I wish for the person to be found, so that the body can be shown a bit of respect and dignity; and I wish that the body be returned to the grieving family members.
However, I think the DA and LE would make an arrest if they have enough evidence; since there hasn't been an arrest, I'm assuming they DON'T have enough yet. I hope for a speedy return of Theresa; but I don't want them to arrest and then charge a person with her murder (assuming there's been a homicide) until they've got enough to have a good shot in front of a jury. If they err on the side of caution while putting all the pieces together, that's okay by me. I'd rather make sure that the murderer (IF there was a murder) hears the cell door slam shut behind him....
