If only the evidence at the crime scene matched up it would be a slam dunk. But nothing matched up, and I have to say if anyone harbored him after the triple murders then they must have really believed his innocence. I don't care who you are if you think someone murdered three little girls you are not going to hide them out. I also think the "THE KILLER WAS HERE BYE BYE FOOLS" was probably a prank because really why would someone write that? I think a handwriting analysis was done and it didn't match his writing. Gene Hart was what 37 at the time of the murders? It just doesn't fit the profile of who did this, he had never murdered before, that we know of. He had no record of being a pedophill in all the 37 years of his life. I am no fan of Gene Hart, he was a bad guy but the bootprint, shoeprint, and fingerprint point to someone or someones other than him. This was planned for sometime, it could have been someone associated with the camp or a former employee who knew the grounds really well.
I agree with the writing being a prank. Something a kid/teen would write.
