and then we hear that there has been someone who has been arrested already not connected at all to that kind of activity, but a man who was making tearistic threats. >> it seems that they are not telling us. it's a fair question. do they know. even in the news conference the other day they did say they aren't any closer to an arrest but they are looking into all those leads. you mentioned an arrest, about nick morale. he was arrested indirectly connected to this case. he allegedly made calls to the tip line for this case and made a threat against a public official. that's why he was arrested. he's being held on a $1 million bond. but even mr. morrell, investigators say he is not the link to this murder case.
