I think a stranger did it. Their same neighborhood had break ins before including the SA, or attempted SA, of a child. In the same neighborhood. But I think when Patsy found JonBenet, she thought the son had done it. So she wrote the ransom letter. And botched the case. And of course the detectives botched it worse. The evidence was in the home including the broken window and the suitcase. There’s also the DNA evidence which just leaves me confused. The case should have and could have easily been solved.
