This one such an operator she is possibly quite certain that no blood at all exists in that area.
Did this story not emerge in response to her receiving news of CSI being at the house?
Did her untrue accusation against RD not emerge immediately in the wake of his release of the CCTV footage? The news station had to come out publicly and state they had not paid him for his interview or film.
If she said the blood was in the garage, would it not be wise to interpret it as there being absolutely zero blood in the garage but possibly lots somewhere else, or none at all?
Need to stay 20 steps ahead of her all the time.

This is entirely possible. I keep thinking about one person I knew well in my life (who was in fact Cluster B), my aunt (so I can write about her here, and she is no longer with us, so I feel it's okay). (Scroll if you're not interested in reading this long post on personality disorders!)
My aunt was, superficially, a wonderful, giving, often funny person (at least, she thought her antics were funny and her siblings sometimes agreed - although, in true borderline fashion, she had managed to split the entire family when she was a teen ager and her oldest brother had not spoken to her since she was 17 and would not be in the same space as her, so that I rarely saw that uncle - my aunt controlled when he could attend family reunions because he would not have his own family around her, I never got all the details of why, but I know enough to understand his decision). She would love-bomb people and my parents used to talk quietly about whether she would eventually turn on me (I was a baby when I first met her) the way she'd turned on every other kid in our family (including her own daughter) when they got to a certain age. My dad said "She likes dogs and babies, but when kids get a mind of their own, she can't stand them."
ANYWAY, that aunt repeatedly disciplined her own daughter (a lovely, sweet girl) by threats of or actual abandonment. For example, leaving her daughter by the side of the road (on the road to Vegas, in Colorado, in Los Angeles). The little girl would sit down and cry. Dad said Barb never moved from her spot. After some time, Aunt F. would come back and ask her if she was sorry and put her back in the car.
That's just one example. My cousin was born in 1938, so I suppose my aunt thought it was safe to do this, but truthfully, I don't think my aunt ever thought about that aspect of her tantrums and fits. She threw things, she ranted, she insulted, then she love-bombed the victim. She did this with both husbands. My dad blamed her for the death of her first husband (long story, I should do a blog). It was an "accidental" death caused, my dad says, by Uncle Ralph's emotional distress and distraction due to something my aunt did/was doing. She tormented her (very passive and submissive) second husband in my presence and when I went to spend a week with her (what were my parents thinking???), he was my ally and savior. She withheld food from her own child (and from me, when I visited) in order to get control. She deliberately made food that her daughter hated in order to mock the daughter or control and punish her. She did this to my dad, too, and to my mom, and to me. She did it constantly to her husband. She had to invent new crap to make in order to accomplish this. It's almost unbelievable.
I still don't know exactly why my aunt was like that. Her father was Antisocial PD, possibly a narcissist. She grew up around him, the younger kids didn't. Her father was a violent man, but never actually hit her (he beat the boys). She was sort of abandoned (she was sent to be a maid for Grandma's cousin when she was 14 and everyone said that's what changed her, but I don't know about that). It's true that she was pretty much on her own from age 14.
My aunt did a long series of minor criminal acts, for which she was either excused or never caught. It's mostly minor stuff (although some of it would be major theft if the victim had filed a report - she took things from the homes of elderly friends and relatives, through a variety of ruses or just outright stealing, but always with an excuse). She constantly violated traffic rules.
She lied blatantly and constantly, usually to sew discord. She loved practical jokes and people who didn't know her well (like neighbors and members of her church) thought she was generous and funny. She loved to get me gifts (up until about age 9-10), usually getting the gifts at garage sales or thrift stores - but I loved them. I still remember the night she decided I was awful. I was doing homework (long division) and she didn't like how I was doing it (teacher taught me). BTW, my aunt liked to pretend she had been a teacher in Kansas, but now that I think about it, that had to be a lie. I don't think she even had a job after being a maid in her teens. So my uncle said we should have a competition. He'd dictate long division problems, my mom would solve them on a calculator and we'd see who was faster and more accurate. I won. She threw a hissy fit (and in fact, ended up leaving our house in the middle of the night, we didn't see her for months, my dad said it was great and my mom even agreed). After that, no gifts of course. In fact, about a year later, she took some of the gifts back (packed them in the middle of the night and took off).
That last example is a classic narcissist move. Unbelievably, she couldn't handle a "narcissistic injury" (any slight or perceived slight to her self/self-esteem) and was of course highly reactive and emotionally labile. The tantrums, throwing things, destruction of property (etc) are more borderline-ish.
When she was 90 years old, she was diagnosed with a brain tumor (that had probably been growing for 5-6 years) but my dad always wondered after that if she had had something organic wrong with her for years...I don't think she did. Sometimes I think maybe her poor brain just couldn't take it any more. Day to day, her life was so dramatic and full of turmoil. Her daughter and family eventually moved far, far away and ultimately, stopped giving her their address for fear she would just turn up (she would have).
