The mother of the suspected Boston bombers has given an exclusive interview to Britain’s Channel 4 in which she reiterates assertions that her sons were set up, and also claims that her oldest son Tamerlan is still alive.

“What happened was a terrible thing. But I know that my kids have nothing to do with this. I know it. I am mother. I know my kids,” Zubeidat Tsarnaeva told Channel 4 News in Makhachkala, Dagestan. […]

Notwithstanding photos that place her other son, Dzhokhar, at the scene of the second Boston Marathon bombing, Zubeidat Tsarnaeva still believes that someone else set up the attack and that her son Tamerlan is not actually dead.

“It’s just somebody did this, somebody set this up, not my kids,” She said. “Whoever is dead over there it’s not my son. The body is half of the body of my son, you know what I mean? So this is not my son.”

Sure looks dead to me:
