DARK MEMORIES FOR BOSTON

The trial, which began in early March after a two-month jury selection process, dredged up some of the worst memories in living memory in Boston. The twin pressure-cooker bombs ripped through the crowd of spectators at the race's finish line, setting off a mad rush to save the hundreds of people wounded, 17 of whom lost limbs.

Three days later, the Federal Bureau of Investigation released images of the Tsarnaev brothers, saying they were the suspected bombers and seeking information on their identities. That set the stage for 24 hours of chaos as the duo fatally shot Collier in an unsuccessful attempt to steal his gun and went on to carjack a Chinese entrepreneur before police found them in the suburb of Watertown.

The pair fought a desperate gunfight with police, throwing a smaller pressure-cooker bomb similar to the ones they used at the race, as well as smaller pipe bombs. When Tamerlan Tsarnaev ran out of bullets in the rusty Ruger handgun his brother had borrowed from a drug-dealing friend, he charged Watertown police officers who were trying to wrestle him to the ground. Dzhokhar then hopped into the carjacked Mercedes SUV and sped toward the group, running over his brother and dragging him.

The city's mayor, Marty Walsh, said he was glad to see the trial moving toward a conclusion.

"I am thankful that this phase of the trial has come to an end and am hopeful for a swift sentencing process," Walsh said. "I hope today's verdict provides a small amount of closure for the survivors, families, and all impacted by the violent and tragic events."
