This case became the story of 1 debit card with 5 copies, 4 (?) phones and 2 diaphragms. Who, in the intelligent universe, would claim they were keeping a diaphragm in their purse for a friend? Even after the detective reminded her they'd test it for DNA, and have their answer in a moment. Several times! She kept right on with her lie. No, she wasn't having an affair. This was, like, the craziest lie I've ever heard in an interrogation. And she had another diaphragm in the glove box of her car? That's where I keep my first aid kit. Different strokes for different folks, I guess.
Call me ageist, but old enough to know that Melody might have been too advanced in years to need a diaphragm? Maybe she used one as a vanity thing? A souvenir? That would be a new one on me, but you never know with some of these criminal cases.
