Jeffrey Paul Delisle, ex sub-lieutenant of the Navy Intelligence admitted that the spying charges against him were true. According to prosecutor Lyne Decarie, he willingly entered the Russian Embassy in 2007 to offer to sell confidential military information. Apparently, he was getting around $3000 per month for his services, but he declares he wasn’t doing it for the money, but for’ ideological reasons’.
He was asked to copy references about the Russians from his work PC to an USB stick, then he took the stick home and uploaded the data to an email application to share it with the people paying him.
