Any time you have a wife go missing the husband or lover is the prime suspect. Most of the time it is the husband or the lover that kills them. Many murders are carried out against a loved one by their partner so it would be a safe bet that he had something to do with this murder. Plus the fact that he has been in contact with a defense lawyer since her disappearance while could be a way to make sure if he is charged to allow them time to gather any evidence to support his claim of innocence or to help make sure they are truly prepared when it is found out that maybe he did kill kill her and charge him. We will have to wait and see.
