The ducks were not important to the case....
Then I guess neither were:
...the necklace (which she did not wear all the time)
...the 2 left shoes (not her size, not considered missing be CPD,her current PAIR of running shoes was missing)
...NC having no $ Friday (she paid for lunch and HT shopping)
...NC always telling her friends who/when she was running with (nope)
...the black dress (she was wearing one earlier)
...the laundry detergent brand
...the cleaned out garage (NC asked BC to do it)
...the 'pristine' trunk (not pristine according to SBI, only CPD)
...the constant yelling/fighting (none according to witnesses)
...NC 'fear' of BC (non-existent according to witnesses)
...BC's squeeze on the side (nope, none)
...NC's painting appointment with JA (highly unlikely at this point)
I'm sure the list can be doubled, but all of these issues were 'important' to the case at some point along the line, and the folks who at one time claimed this have now run quickly in the other direction.
