Feds: Homeland Security analyst had parts for explosives at home 

A U.S. Department of Homeland Security analyst who entered his agency’s Washington headquarters with a gun and other weapons in June also kept ingredients for explosives at his home in West Virginia, according to court documents.

A document detailing a June search of Jonathan Wienke’s Martinsburg home was unsealed Tuesday in U.S. District Court in the same city. Wienke, a 45-year-old federal employee with top-secret clearance, had a 75-minute commute to the Homeland Security building.

Authorities found sawed-off plastic pipes, glue, tools and 10 boxes of magnesium shavings, thermite and oxidizers in the house. In the filing, a Bureau of Alcohol, Tobacco and Firearms and Explosives agent determined that the items could be used to make explosives, but said they weren’t contraband in their present state and didn’t seize them.
