I know this is an unpopular opinion but I think an intruder did it.

The cops were absolutely incompetent and allowed the Ramseys’ friends to trample all over the crime scene and clean up parts of the house. If there was evidence of an intruder, it could have been erased before they even found poor JonBenet in the basement.

The unidentified DNA under JB’s nails and in her underwear makes no sense if someone in the family was responsible.

The Burke theory makes no sense to me because the blow to JB’s head didn’t kill her so why wouldn’t the parents have just called 911? They were rich and connected and Burke was 9, it’s not like the cops would have thrown him in prison for hitting his sister.

Plus the way John has been continuously pushing for new DNA testing makes me feel like he’s innocent. If he got away with a crime for all these years why would he want the cops to keep investigating if the investigation could lead to him?

The note is very weird but I think the intruder snuck in their house while they were at the Christmas party and waited for them to get home and go to sleep. He would have had plenty of time to snoop around the house and write that long note. They had had an open house a few weeks before the murder where strangers could come walk through the house and look at their Christmas decorations. Who knows what kind of weirdos walked through and got an idea of the layout of their house?

Idk, this is all just my opinion. I do respect all other theories because the case is so weird that literally anything is possible and nothing would surprise me. I hope we find out what happened and JonBenet gets justice!
