I'd be very interested to know details of the supposed search of the 'completely dug up' construction area.
1) Was it actually searched? Is there proof it was searched? Are there people who took part who'll vouch for that?
2) When was it searched? Monday the 3rd of April? Week later? Month later? Certainly, the 'completely dug up' areas at some point were filled and/or paved. When did that happen in relation to time of any search?
3) By whom was it searched? LE? Volunteers? Dogs? Whose dogs? Any digging done?
4) Was the entire construction area searched? The entire building? Crawl spaces?
5) Any unusual odor detected in the Sunshine Market space when it opened for business? Other spaces?
Anecdote: I've spent many hundreds of hours of my life searching - for buried Civil War relics - using a metal detector. I know from experience when I'm on a new site for the first time, my results improve after I've found that first relic. In other words, after I know for sure soldiers were there and there are relics in the ground, suddenly I start to find stuff more quickly. Just human nature. When you know - rather than suppose or hope or wonder - that what you are searching for is there, your focus and intensity greatly improve.
Now, the lead detective himself expressed doubts - understandably - as to why in the world Brian would have entered the construction area. If that was the mindset of searchers, as opposed to, say - we're 90% sure he's here, let's find him - that mindset may well - based on my anecdotal experiences - have impacted results. Dogs on the other hand, shouldn't be impacted by this sort of thing. But their handlers might....
Good questions but I'm of the opinion we are never going to get the answers. This is a 12 year old cold case and on top of that I'm not sure if Det Hurst would answer all of them. The sad thing is when he was nice enough to answer questions IMO I don't think the questions were all that detailed. We have got a few more answers but nothing that really digs deep (no pun) into details most people would like to know.
