I know you're as shocked as I am. Michael Patrick Leahy of the Boston Herald reports:

On Tuesday, Massachusetts Health and Human Services spokesperson Alec Loftus confirmed to the Boston Herald that deceased Boston bombing 'Suspect 1' Tamerlan Tsarnaev received welfare benefits from the state until 2012:

State officials confirmed last night that Tsarnaev, slain in a raging gun battle with police last Friday, was receiving benefits along with his wife, Katherine Russell Tsarnaev, and their 3-year-old daughter. The state's Executive Office of Health and Human Services said those benefits ended in 2012 when the couple stopped meeting income eligibility limits.

But wait; there's more.

So was the woman who married him, Katherine Russell. And their daughter. Although many of those benefits were stopped in 2012 when income eligibility limits were reached.

But wait, wait, there's even more; both parents had received benefits. As well as Dzhokhar.

Note the timeline in this Boston Herald article. Some benefits no longer paid, some ceased for other reasons.

The $64,000 question remains. Where'd they get the money to finance their lives, travel, live in one of the most expensive places in America and get themselves weaponized.
