KK created red herrings. She had KB's gun, gave it to old HS pal MP, lying to him that it was KK's aunt's gun. KK had MG's gun, and returned it missing one round with a round in the chamber. Why did KK do these things? Why did she use these innocent people in her scheme? KK claims that although she was not present for the murder, a gun is not the murder weapon.
Back to blood from a couple of KB's tampons in the trash. Soaking in a dish of sterile water that would evaporate would expand the bloody liquid available to spread around. Why do this? KK claims the whole townhome was bloody when she arrived and she cleaned it up. She has no idea other than she says that PF killed KB with a wooden baseball bat. So if CBI finds that the blood is menstrual blood with tampon chemicals, PF must have planted it. The Defense will say KK planted it, and also CB1 and CB2 might have planted it in their grief and zeal. The jury will be confused, but the blood will be excluded as from a baseball bat attack. And conveniently to KK's tale, the wooden baseball bat murder weapon was all burned up.
I don't believe KB was murdered with a gun or with a baseball bat. I don't believe the candle scent sniffing story either. KK also has an out - she will say she isn't lying, PF told her!
The people to look at in KK's world are not the known people innocently caught in her web of lies. She used each person for a purpose: MP to hold KB's gun, MS to get free legal advice, MG to borrow a car and gun. Both MG and MS were the recipients of her solicitation stories, KB needing cover for her presence in WP on those dates. And Aunt K, another innocent bystander.
Why would anyone NOT think KK planted evidence?
