Ummm....it has been mentioned multiple times in this thread. LEO had tunnel vision and railroaded JY.
I have said that I believe that investigators had tunnel vision. I am of the opinion that they looked for any information that would bolster their theory. I have cited the "evidence" of the rock in the propped open door. The door was always unlocked at 6AM, so Jason had no reason to prop open the door because he knew that he could not return to the hotel prior to 6AM. Still, police attribute the propped door to him because it fits their tunnel vision theory of the crime.
Another point is the cameras. One camera was tampered with. There is no evidence connecting Jason to that camera. Still, in order to bolster the police theory, they claim that Jason tampered with one camera. I believe there were 14 cameras in the building. Jason's room was on the fourth floor. We are to believe that he tampered with the camera at one exit, but not with any of the other cameras in the hotel. Miraculously, none of them captured him re-entering the hotel in the morning. This is also a problem for the police theory.
We also have the fact that hotel witness stated that he found the room door securely closed when he placed a newspaper on the handle and a receipt under the door in the middle of the night. Police refuse to accept this witness testimony because it doesn't fit their theory. Instead, they insist that the door was not secured. The eye witness statement is ignored. Police imagine that the door was not secure because the true fact does not fit with their tunnel vision theory.
The gas station attendant was not shown a number of suspects. Police had tunnel vision and Jason was their only suspect. They knew they should show a photo array of similar looking suspect to the witness, but they didn't. Why didn't they do that? Were they concerned that the witness would not identify their suspect?
Why did police tell the medical examiner that it was not necessary to complete a sexual assault kit? If this was a home invasion, a sexual assault kit would be at the top of the list, but police had already formed their only opinion about how the murder occurred, and they were not interested in any other theories.
