Excellent theories, Pepper. I always thought it was related to the pageants, too, as it would be so easy for some jealous person or pedophile to get into them and follow JonBenet's progression in them. But a female murderer...wow, that's a good one! I thought the ransom note handwriting looked very female, too, if the one shown in the book A Mother Gone Bad is the correct copy.
This murderer may very well have committed the "perfect" murder. That, combined with the Barney Fife mentality of the Boulder PD means that this case is so cold it probably will never be solved.
I know the Ramseys lawyered up early, and some have held that against them suggesting that only guilty people would get a lawyer so soon. That, however, is not enough to convict, let alone indict.
Let's just look at the recent case of Jessica Lunsford. Many, including me, were ready to say that the family must have had something to do with her disappearance. Look how we were proven wrong. Had that PD been careless and not followed up on the sex offenders in the area, her murder may also have been unsolved, with nearly everyone suspecting the father and grandparents.
I have believed for the past couple of years that this crime was committed by a woman intent on making it look like a man did it. My reasons for this belief are,
1. The ransom note - appears to be written by a woman. Way too long and detailed for a man to have written it. It just "smells" like a woman to me. <very unscientific, I know!

The details of the note, including the odd amount seems like a message to the Ramseys, rather than an actual demand for money. Like, "I know what you just got (bonus money) and I'm getting even."
2. The sexual overtones. As I recall, it didn't appear to be rape, but more like penetration with an object or a finger. Again this is consistent with a woman wanting to implicate a man.
3. A woman, being a smaller size and lighter on her feet than a man, might have been able gain entry and move around in the house without being heard.
4. JonBenet might not have been afraid if awakened by a woman in the middle of the night, as compared to a man, especially if the woman was someone she knew.
5. Motive. I don't think there was ever a motive for ransom or money. I think the motive was NOT sexual. Likewise I don't believe there is any sort of motive for the Ramseys to have been involved. It just doesn't make sense to me for the reasons I stated in my previous post. Therefore, I believe the motive was jealousy. Those most likely to commit a crime based on jealousy are women.
I think if there are any investigators left on this case, they should look closely at any women that were involved with Patsy, possibly within the pagents - but outside as well. Especially any women that might seem a bit bent with personality or psychological problems in the past.
