One member of pirate was charged.
He is a monor, but a judge said to treat him as an adult.
His father said that he was 15, but prosecution think he is over 18.
If he was imposed the biggest guilt, he would be imposed life sentence.
We can see the difference of regarding as an adult from this article.
