Jonathan James was the first juvenile to be convicted and jailed for hacking in the United States. Starting at 15, he hacked into Bell South, the Miami-Dade school system, NASA, and the Department of Defense, and stole software said to have been worth $1.7 million from the government. He intercepted the source code of the International Space Station, which, when discovered, caused NASA to shut down its computers for three weeks, costing $41,000. He was sentenced to six months of house arrest and probation until he turned 18. Even worse? The court required him to write letters of apology to NASA and the Department of Defense. 

After Albert Gonzalez's hacker team stole credit and debit card information from TJX in 2007, the Secret Service investigated James, who claimed he had nothing to do with the thefts. Out of fear of being prosecuted for crimes he didn't commit, James killed himself in his shower in May 2008. “I have no faith in the ‘justice’ system," his suicide note said. "Perhaps my actions today, and this letter, will send a stronger message to the public. Either way, I have lost control over this situation, and this is my only way to regain control."
