Authorities say a Watertown homeowner noticed blood near a loose strap on a tarp covering a boat in his backyard and called police.

Thermal imaging showed that the suspect was still alive, but not moving. After a standoff with police, Tsarnaev was taken into custody with gunshot wounds to his neck and leg.

Mass. Gov. Deval Patrick told reporters on Saturday that Tsarnaev is in serious, but stable condition at a Boston hospital, but the suspect is unable to communicate.

We "hope he survives, because we have a million questions,"  Patrick said.

The discovery in the Watertown backyard came shortly after authorities announced that a lockdown of the Greater Boston area had been lifted, admitting that a door-to-door search of Watertown had been fruitless.

The lockdown had been announced Friday morning after a bloody shootout with police that ranged from the campus of the Massachusetts Institute of Technology in Cambridge, Mass., to the streets of nearby Watertown.

Tsarnaev's older brother, Tamerlan, was fatally injured in the shootout. The two brothers are suspected of being behind the bombing that killed three people and wounded more than 170 on Monday.
