The married couple who tried to sell nuclear secrets is taking different defense strategies, with the husband not fighting being kept behind bars ahead of the trial while the wife contends she had no idea what he was up to and wants to be freed from jail.

Jonathan Toebbe, a nuclear engineer at the Navy’s Nuclear Propulsion Program, and his wife, Diana, have been accused of espionage-related charges following alleged efforts to sell nuclear submarine secrets to an unnamed foreign government in exchange for tens of thousands of dollars in cryptocurrency. The two appeared separately before Magistrate Judge Robert Trumble of West Virginia on Wednesday.
