I think we tend to forget several things. I read earlier on there were 20 officers assigned. So you have to send some to Virginia to trak the husbands whereabouts. Some remain to check out other leads, some are interviewing family and friends and so on. Someone has to the follow the route the husband took from VA to Brevard making stops along the way to show pictures, ask questions and so on. Someone has to write warrants to get phone records, credit card statements and on and on and on. When all this comes in it all has to be gone through and reduced to something usable.
This is an enormus task to undertake - it is not like they are entirely focused on one thing. We have close to a hundred pages of blabber about this case already - imagine how many pages they have ! Since the husband has not been actively participating, that we know of of, the police are spending a heck of a lot of time trying to just figure out where he was, how he got there.
Today the Wake County Sheriff's office is also involved in a massive manhunt trying to capture two armed men who are they suspect located in a neighborhood. So do they try to catch these guys with guns and protect the people of that neighborhood or do they ignore it and investigate this case? I think they have more than one thing to do - be patient - give them a break and the time needed to identify this murderer and collect the evidence necessary to put the murderer away. JMO.
Close - I am waiting on DMV info - impatiently of course.
