Bellamy Blake
You're a Grounder and the only crime you've committed was betraying your people.
Finn Collins
Being born, your mother had twins and since you were the youngest you were thrown into prison once you were 14.
Monty Green
You weren't arrest, you came down to Earth along with Raven.
Jasper Jordan
For being born, when Octavia had gone off to the dance with Bellamy you went after her and instead of telling her to come back, you were amazed by the music so you stayed and you both had gotten caught.
John Murphy
Your mother had told you that she had done certain 'deeds' for the chief of the guards so you would have extra food to eat and medicine. You told your father - Kane - who didn't do anything so you took matters into your own hands. You tried to talk, and reason with him but in anger he had punched you, which was a huge mistake. You were feisty and short tempered so you fought back but that only resulted in 'accidentally' beaten the guard to death and while you were locked up your mother was floated.
