1) His parents were killed when he was quite young, and he was placed into a foster care system for his childhood. No one wanted to take him in, so he left when he was old enough to, there he lived in hostels, on the streets, begging, stealing, whatever he could to survive.
He then met a gang that would take him in, that's where he learned computers and found he was quite good with them. To make money, that was heavily taxed by the gang, he would get info for blackmail, freeze and hold systems up for payment, that kind of work.
He was caught and arrested, was sentenced to a number of years in prison before he was recruited by the department to help solve computer based crimes. He would be given a small payment, and a reduced sentence. When he got out, they kept him, allowing him to live in a small apartment and enough to pay rent and food.
His old gang left him a present for when he got out, debt, a large amount of debt, and the banks want it back with interest.
2) Currently does IT work for small businesses where he can be paid under the table.
3) Fascism killed his parents, they were outspoken of their hate for their leader and it had them killed, publicly. His entire life was changed that day and he blames them for everything.
4) Currently lives in LA where there are plenty of small businesses that could use his skills and allow him to survive in the world he lives in, away from his old gang, away from his old life.
