Hello and thanks for requesting me.
I think you correctly told your husband not to talk to the police. It is never a good idea for a suspect of a crime to submit to interrogation
. The police are trained as interrogators. They are highly skilled at it and very manipulative as well. So they can twist what gets said into admissions of guilt.
When you submit to interrogation without knowing precisely what evidence the police are looking for, anything said -- even that which the suspect thinks is harmless -- can be hurtful if it corroborates evidence given to them by the complainant.
By not providing evidence, he likely did himself a huge favor, because it appears to me that the police realize that this child does not tell consistent stories, and that they don't have a case they feel certain about. The fact that they have not arrested your husband given the serious nature of these charges supports the fact that they don't think that they can presently make the charges stick if they take him in.
Things can change, of course. The state is still investigating. But it's a very good sign that he has still not been charged.
As far as taping your daughter is concerned, Wyoming is a one-party state when it comes to recording telephone conversations. That means that as long as one of the parties to the taping knows that the conversation is being recorded, it is legal in the state of Wyoming. So the fact that your daughter did not know or consent to the taping would be irrelevant so long as the other party to the conversation knew it was being taped.
