Washington – A United States Navy engineer’s wife has pleaded guilty to helping her husband try to sell secrets about nuclear-powered submarines to a foreign country.
Diana Toebbe, 46, acted as a lookout while her husband left information at a “dead drop” spot, once hiding a data card inside a peanut butter sandwich.
A former teacher, she will go to prison for up to three years under her plea deal with federal prosecutors.
Her husband, Jonathan Toebbe, 42, pleaded guilty earlier this week.
Under his plea deal, he will receive a sentence of about 12 to 17 years.
Both of the Toebbes pleaded guilty in federal court in Martinsburg, West Virginia, to conspiring to communicate restricted data.
The crime carried the possibility of a life sentence.
Jonathan Toebbe was an expert in nuclear-propulsion systems on submarines, one of the nation’s most closely guarded secrets.
He tried to sell the information to a foreign government, sending messages to someone who he believed was a foreign official, according to the justice department. In fact, the individual was an undercover FBI agent.
Before their arrest in October, the Toebbes lived with their two children in Annapolis, Maryland, home of the US Naval Academy.
Diana Toebbe taught history and English at a private school. She has a PhD in anthropology from Emory University in Atlanta.
Jonathan Toebbe served in the Navy before becoming a member of the military reserve. He worked in the office of the chief of naval operations in Arlington, Virginia.
Prosecutors had argued the Toebbes were a flight risk, citing messages between the couple about quickly fleeing the US.
Diana Toebbe’s lawyers said those messages were about her dislike of then-President Donald Trump and had nothing to do with the plot to sell classified information to a foreign nation.
For years, according to the investigators, Jonathan Toebbe collected information on nuclear submarines, smuggling documents out of work, a few pages at a time, so that he could get past security checkpoints.
“I was extremely careful to gather the files I possess slowly and naturally in the routine of my job, so nobody would suspect my plan,” he wrote to the investigator, the individual who he believed worked for the foreign government.
Toebbe, unaware he had fallen into the trap, came to trust the investigator. (BBC)
