To the brazen teen accused of hacking into his high school's computers to change not only his grades but those of some other students as well. In return for money.

Reporter: He faces four counts of allegedly hacking into compute toers change grades. There have been his Pers over the last week or so. More and more information started to come out. Then we saw that he was arrested. Reporter: A school spokesman said this was an isolated incident. The details cannot be shared at this time. My guess is, not only will he not graduate with his class. He may not see unsecured daylight for quite a number of years. Reporter: In a bond hearing on Friday, his public defender argued the prosecution is overcharging the teen. There's no legal basis for four counts of either of the charges.

I asked for a car. I got a computer. Reporter: But in real life, the stakes are higher. And so are the consequences.

Reporter: For "Good morning America," Michelle Franzen, ABC, New York.
