I must have missed the post, where is the article that shows the timeline of the incident?
Apparently the gym has 4 cameras, and they take stills. They aren't releasing any of the stills that show other kids, so clearly Kendrick was not alone in that gym.
The crime scene photos show Kendrick's shoes resting near his legs inside the mat, so why would he be reaching for a shoe if he already had his? The positioning of the shoe seems to indicate that they were tossed in after he had been put in upright.
It seems to me that the surveillance video would have been looked at before they finished gathering evidence, so if someone saw certain people they knew and didn't want to be connected to the crime, they probably would have taken steps to corrupt the evidence, like not further testing blood on the wall, or leaving other shoes and shirts that were found in the area.
I don't know about the disposal of organs, I'm guessing that not having them around means they cannot be tested if another autopsy is done. Since the case was closed rather than called a murder, I guess that's why they didn't feel the need to keep the organs preserved.
I find the interview with this police lieutenant interesting. When asked about the blood, he says it doesn't appear to be related to 'our crime'. So he's admitting it wasn't an accident? Freudian slip.
