Perhaps while LE was digging beneath the concrete they had eyes on BM wherever else he was. IMOIMO-stuff here...but I've always found LE's statement 'investigation revealed'... the bike ride: this was due to someone saying she'd gone on said ride & indeed finding the bike very quickly
However, since the bike ride has never been confirmed & if I'm correct never once mentioned by LE in their statements after that initial one PLUS - no mention of the bike ride in the release today...
LE knows the bike ride never happened & whomever suggested it is probably suspect numero uno
&.....I just can't help but feel that search of the property, the tearing up concrete, all those blatant pics of FBI sifting - it smacks a bit of LOOK OVER HERE to me
Maybe LE had every reason to search there but perhaps they wanted to see how any POI would react
ALSO perhaps it was a 'look over here' while they searched another area entirely, very quietly & with no fan-fare.....& that location was much more pertinent to the case
