Still think this call could be major (and so hoping it's a strong link leading to Lisa). But, the more I wrack my brain about it, there are reasonable scenarios that would render it unrelated and insignficant. LE and the FBI electronics experts and crime investigators are smarter than I. They knew about this early on. They questioned MW 4 times (according to her, at least). If she really received a call and has been questioned 4 times (we only have her word, for now), then LE knows her friends, family and associates. They've done their homework, imo.
This call is either huge and being kept very close to the vest, or it's nothing at all (no middle ground on its significance, imo). I don't for one second believe KCPD and FBI let a potential lead like this go. Stepping back a little, I can now see how this call might be less important than I originally thought. For example, could be Debbi's dad cancelled his old phone number before giving Debbi his phone and it had just been reassinged to somebody in that area code who knows MW. LE could have said the call came from the Irwin phone because Debbi claimed that she had dad's phone at the house and gave LE that number. So, LE told MW about the call coming from the house based on Debbi's story, rather than using ping data to determine the locaction of the caller (and LE may or may not have known the phone number ownership had just been tranferred to someone MW knows). MW could have really just missed a call in the wee hours, but LE led her to believe it was answered and questioned her multiple times before ruling her out. Had to be certain. Just one example of how this call and MW could be rather meaningless in finding Baby Lisa.
Doesn't appear MW retained a lawyer (if so, would her lawyer permit her to do an interview if she were incriminated?). Doesn't appear Stanton was even aware of this call to MW, per his admission that he never spoke to MW, on Judge Jeanine last night. As the PI, wouldn't he have the phone records for Debbi and Jeremy's phone numbers and scoured them?
On the fence regarding the significance of an alleged call to MW from the Irwin home. Waiting for more info...
