I'm not sure. If I have to be honest I think she used the harshest of punishments for Oscar, yet there are so many things that can happen onward that is unknown.
They can now apply for appeal, which Oscar's camp already noted that they aren't going to do that. The state could also appeal, and there seems to be murmurs that it will indeed happen, Which IMHO is a bad idea for the state, as they will not get a harsher punishment for Oscar than what he already got. The judge also used case law of a similar case with different results, which she used as a baseline. In that case the husband shot through a door and killed his wife. The difference was he didn't know that there was someone behind the door, and he also took just 1 shot. The husband got 3 years house arrest.
Oscar has already been handed over to the department of correctional services, and will spend his first night in jail tonight. He can serve 1/6th of his sentence and then apply for house arrest due to his disability, and then serve the rest of the term at home. The state can even make a deal with him to lessen the sentencing period.
I think his athletic career is over, to be honest. The Olympic committee of Rio 2016 has already issued a statement that he will not be allowed to compete at next year's Olympics.
