BBM1: To me, based on G's re-post by me above, and Epiph's re-post of ASWDH's similar summary, it sounds like they did.
BBM2: To me it would. In fact, somehow I got it in my head that MMQC told us this is what happened, but I couldn't find it anywhere. Maybe I mixed it up with G/AWSDH's posts, which do make it sound like the BF/F was questioned? That's why I posted that Q about this to MMQC a page or two ago. That would surely cause any mother a breakdown.
I know conspiracy theories abound, but putting those aside for a moment, the question burning through my mind is: What could SL's BF/F have told LE that would lead to a decision like "will not handle"? If SL ran off from the BF/F at 6, there is plenty of time between then and 10 for someone to put themselves in the middle of things. If, for example, someone told the BF/F something that made him believe SL "took off," thereby leaving him "suckered," could the BF/F have passed that on to LE? And who would that person have been? Did the person truly know something? Or did s/he have a personal agenda? What is it that turned the BF/F to anger, rather than grief, and made LE choose not to "handle"?
BBM3: Given what appear to be the respective roles of JL, Sr., and EL in the family (e.g., EL, alone, searching the mall immediately after the BB/F's visit, calling LE that night, searching WC and other areas over the next few days w MMQC, hiring a PI shortly after, and doggedly insisting that MMQC knew something), I do not see this.
I cannot begin to grasp what a person who suffers this kind of tragedy must feel. I can only go by what I see others doing in the cases I read about and my own dreadful imaginings. And what I come up with is the time for silence is when you know your child is dead. In the meantime, the force pushing you on is that they may be somewhere, need help, need to be freed, need to be found. I think it is exactly hope that has to drive you to act. JMO.
