Police: Second explosive found in record cache in San Diego County
Authorities have found a second homemade explosive and more of a type of explosive previously discovered in a house in an unincorporated area near Escondido, California, officials said Thursday.
The house occupied by George Djura Jakubec, a computer software consultant who is now under arrest, has been described by authorities as a bomb-making factory. They say it holds the largest cache of the two homemade explosives ever discovered in one spot in the United States.
San Diego County authorities confirmed Thursday they have found pentaerythritol tetranitrate, or PETN, a favorite of al Qaeda bomb-makers that is now the target of new U.S. airport body scans and pat downs.
