more recently: his experience in prison has already resulted in one suicide attempt http://www.advocate.com/politics/transgender/2015/06/19/ky-petersons-mom-my-sons-life-danger
You can take everything they say Ky has going against him and throw it all out. It's true that everything they list stands in the way of fair and just treatment but there is one thing that gets little mention.
Ky admitted that he committed the murder and gave three different versions of what happened. No district attorney should be able to lose this case. With three different versions Ky's story will have no credibility, despite the reasons he might have for not being upfront with the police. Without amazing representation he loses.
If he had kept his mouth shut everything that is stacked against him might mean that the outcome would be no different but there isn't even a chance of it being different because he talked to the police.
