Pro/Con on the Jonbenet Case

After doing much research on this case I have come up with pros and cons that will help me determine my side on which I will argue. On the pro side (pro being that her parent/s committed the crime) there is motive, reasonable theories and cause for her one or both of her parents to kill Jonbenet. The Boulder police believe that one theory could be that Patsey (the mother) got into a fight with Jonbenet over the outfit that she was to wear on Christmas Day and in a fit she strangled her and then bludgeoned her over the head with an object. When the father John found out, helped his wife cover the crime and make it seem like a kidnap. Also they never really cooperated with the police. Although many people want to believe that this is what really happened, there are just too many holes and not enough evidence to pinpoint the crime to them. On the con side, the DNA evidence that was found at the crime wasn't matched to any of the Ramsey's DNA. Even though the body and house was tampered with before it could have a proper crime scene investigation. Even though this case has been opened for over a decade now and no one has been linked to the case, I believe that one or both of her parents were involved with her death and although there were no DNA samples doesn't necessarily mean that they should rule out the parents. So the side I am going to take is the pro side in which her parents were the killers of their own daughter.
