Confessed murderer Dzhokhar Tsarnaev will now be the one pleading for his life after a federal jury took just 11 hours to find him guilty of the 2013 Boston Marathon bombings and aftermath that left four dead and 260 maimed and injured.

“I’m grateful for the outcome,” said Liz Norden, the mother of brothers J.P. and Paul Norden who each lost a leg in the bombing, outside the courthouse. “Justice would be the death penalty.”

In a silent courtroom, a clerk read aloud the verdict finding Tsarnaev, 21, guilty of all 30 counts including conspiracy, use of a weapon of mass destruction and the murders of restaurant manager Krystle Marie Campbell, 29, Boston University graduate student Lingzi Lu, 23, and Martin Richard, 8 at the marathon finish line, as well as MIT Police Officer Sean Collier three days later.

Tsarnaev swayed slightly on his feet, his head down, as the verdict was read and as the forewoman of the jury stared directly at him. He showed no reaction.

The bombings shocked the country and gripped the region as hundreds of maimed victims filled emergency rooms, and law enforcement cast a vast dragnet for the suspects, culminating in a daylong lockdown of greater Boston. The trial presented a narrative of those four crucial days in excruciating detail.

“I couldn’t help but imagine what it would have been like to have been one of those family members reliving in very graphic detail one of the most and in many cases probably the most horrible moment of their lives,” Gov. Charlie Baker said, speaking at the State House moments after the verdict was delivered. “To this day I continue to be amazed that somebody could stand there for four minutes in front of Martin Richard and place that device right next to him.”

The jury’s work is far from done. As early as next week, the same 12 deliberating jurors will reconvene for the start of Tsarnaev’s sentencing trial, where they will decide if he is to serve out his days behind bars or be ordered put to death.

U.S. District Court Judge George A. O’Toole Jr. cannot overturn their choice; however, in the event they do not reach a unanimous decision, O’Toole will automatically impose life without parole.

“For a crime like this, I would support the death penalty,” Baker said. “But obviously this is a decision that gets made by the jury.”

Tsarnaev’s defense team had admitted in their opening statements March 4 that he had conspired with his older brother Tamerlan to carry out the Patriots Day terror attack near the marathon finish line, and that he did nothing to stop the subsequent murder of Collier in a failed bid by the brothers to get their hands on a second gun.

Painstakingly chosen from a record-setting pool and by a selection process that took two months to complete, the panel of seven women and five men breezed through the complex indictment after receiving the case Tuesday morning at 9:12 a.m.

The trial had lasted four weeks.

Tsarnaev, an ethnic Chechen Muslim, became a naturalized citizen of the United States just six months before he and Tamerlan detonated two shrapnel-packed pressure-cooker bombs on Boylston Street April 15, 2013.

Testimony revealed after the bombings, they went about their daily lives – Tamerlan, living with his wife and daughter in Cambridge, and Dzhokhar, returning to the University of Massachusetts in North Dartmouth, where he was a sophomore flunking his classes.

Collier was executed in his cruiser the night of April 18, 2013, as the Tsarnaevs, whose photos had just been released by the FBI as the bombing suspects, loaded up a Honda Civic with a third pressure cooker bomb, an explosive made from a food storage container and several pipe bombs. Prosecutors believe they were planning a second attack in New York City,

That trip was thwarted when the brothers carjacked Cambridge entrepreneur Dun Meng’s Mercedes-Benz SUV and Meng escaped.

While returning to Watertown the morning of April 19, 2013, to collect the Civic they’d ditched there earlier, the Tsarnaevs engaged police in a firefight from which Dzhokhar escaped after running over and killing the wounded Tamerlan.

Dzhokhar, himself shot in the gunfight, surrendered several hours later when police opened fire on a backyard boat, The Slipaway II, that he had taken refuge in.

Today, Tsarnaev was escorted in by security for the reading of the verdict, and he shyly looked up as the jury entered the room, adjusted his jacket collar and nervously ran his left hand through his dark hair. His defense lawyers, Judy Clarke and Bill Fick both placed comforting hands on his back before the verdict was delivered.
