True. LE likely could not verify that the gun was in a different condition. It was just a statement made by a witness.To me there is a difference between something in the affidavit that says, According to MG the gun was in a different condition than she left it. They don't say however that we were then able to verify that it was in fact to be the case.
They do however say things like KK said she was at KB condo on such and such a date and We (LE) were able to verify this through phone records.
KK told us that PF called her and told her she had a mess to clean up and based on cell data we were able to verify that she was in CO on such and such dates.
KK told us where PF took KB body and we were able to verify that with cadaver dogs. etc etc
There are statements in the affidavit that have not necessarily been verified by LE in my opinion. But to say none of it has is not accurate in my opinion.
But I do think much of the important information is backed up with evidence. They can't confirm the use of the baseball bat either unless they find some of the remnants. I don't know how completely a wooden bat would burn. Imo
