Were they Tamerlan Tsarnaev's? Or was his wife radicalized as well and participated in the planning and execution of the terrorist attack?

Fox News:

Radical Islamic materials and an al Qaeda magazine were found on the computer of Boston Marathon bomber Tamerlan Tsarnaev's widow - and there was explosive residue throughout their house, it was revealed yesterday.

The files found on Katherine Russell's hard drive are part of an investigation into whether the woman - who claimed to be in the dark on her husband's terrorist activities - was aware of his plan to set off the two bombs, The Washington Post reported.

It wasn't clear whether the files belonged to Russell, 24, or her husband, 26.

The explosive residue was found on the kitchen sink and table and in the bathtub at their home in Cambridge, Mass., a source told CNN.

The surviving bomber, Tsarnaev's brother, Dzhokhar, told investigators they built the bombs in Tamerlan's basement.

I don't know about you but I find it very suspicious that this woman claims to be in the dark about her husband's plans but didn't notice the bomb ingredients in the bathtub? What did she think it was?

I feel for this woman's American family who evidently didn't have a clue what kind of man their daughter married - or what he may have done to poison her mind.
