The above video, provided by the FBI, appears to show Mascheroni walking an undercover agent through the nation's energy posture and advising Venezuela to acquire nuclear weapons. The video was shot during one of several meetings between Mascheroni and the agent in March 2008.

Mascheroni received at least one payment of $20,000 for his efforts, though the FBI declined to release the total amount he was paid during the sting operation.
He was charged in 2010 with conspiracy to communicate and communicating restricted data with the intent to secure an advantage for a foreign nation. He ultimately pleaded guilty to conversion of government property, retention of records and making false statements.
Mascheroni's wife, Marjorie Roxby Mascheroni, 71, who also worked at Los Alamos Labs, was also convicted of conspiracy and making false statements. She was sentenced in August to a year and a day in prison, followed by three years of supervised release.
