Scientist Pleads Guilty in Nuclear Spy Case

A one-time Los Alamos National Laboratory scientist and his spouse confessed in court on Friday to attempting a sale of U.S. nuclear-weapon secrets to Venezuela, the Albuquerque Journal reported.

Physicist Leonardo Mascheroni, 77, and his wife, Marjorie Roxby Mascheroni, respectively face minimum prison terms of 12 months and 24 months for supplying classified weapons information to a federal agent posing as a Venezuelan operative.

The United States has not officially suggested Venezuela was seeking classified data, the Associated Press reported.
