Like everyone else, I'm watching the footage and listening to people saying things that don't reflect what I'm seeing - A poor old disoriented guy having a psychotic break and if anyone was chasing him it was the demons of his mind.
Like someone else said, somehow he made it into the dumpster. Possibly hiding from imagery pursuers and ended up getting crushed. I don't he believe was mugged and if he had died in a mugging, the injuries would be different.
There was no break-in. He made that mess in the house, firebombed his neighbor, lost is phone and wallet and while having a mental breakdown, went wandering the streets and familiar places, babbling nonsense.
Is is this sad? Absolutely. Sad ending of an obviously very bright, accomplished man who served the public and for his family.
But let's not brush aside forensics and police procedure to make everything a mystery or conspiracy theory. Cops are pretty good at sussing real and staged burgleries. Not that he staged it. He simply had a "fight" with imagery offenders.
Not a good beginning when viewers are fiddling with their phones looking up, and, saying, nope, that's not a guy running from pursuers, that's a guy whose cheese is not firmly on his cracker, disoriented, and simply wandering the streets. Too bad the pharmacy didn't recognize his condition and call the cops.
Sad, but no mystery.
