It's a good bet that, when a young person in a highly-developed country dies and the announcements about them do not give a cause of death, they killed themselves. Given that he was white and had announced an intention to kill himself the night before, it's almost an open-and-shut case.
Its a possibility certainly but its also possible that the cause of death is not yet know, and wont be until an autopsy is carried.
Given other people are talking about other erratic behaviour over the last few days then an aggressive brain tumour or bleeding into the brain would also be possibilities. Best not to jump to conclusions too early (the same is also true for those suggesting police brutality as the cause)
>> What happens in a case like this where the police are possibly suspects in a death?
Normally if someone dies while in the custody of police there is automatically an inquest as to what happened. If there's evidence of mistreatment or abuse, the District Attorney can then decide to send the case to a grand jury and let them decide whether they should charge the officers involved. The DA can also indict and charge the officers without a grand jury. In most cases, DA's send their cases to the grand jury in effect to "test" how strong the evidence is they have.
In the Ferguson case, the grand jury waded through thousands of documents and decided the conflicting witnesses testimonies and physical evidence made them decide not to indict officer Wilson for the shooting.
Even if the DA decides not to prosecute (for whatever reason), then the family can hire an attorney and file a wrongful death case (violation of constitutional rights) as a civil suit against the city. Civil cases also have a lot lower burden of proof or what we call "the preponderance of the evidence" meaning its more likely something than not something happened.
This is a fairy tale. In reality, municipalities don't go much out of their way to uncover their own wrongdoings. It is fallacy to assume that this would be handled properly.
That's pretty conspiratorial. I think its a safe bet your alternative idea is not anything like what happened. Do we even know if there were any police. It's a very sad situation but there is no information and not clear if there is any investigation planned.
