LE in that case had their eye on him from day one. The perp actually sat with the family at a vigil when she was still just missing, and her mom held his hand, although she suspected him. Very difficult !
So, LE not saying something, or being closed mouth, is not unexpected.
5) They are looking at someone outside of the known family -- but who may be known to the family (friend or associate) and maybe not in a good way ?
