“This day helps us remember that in the face of tragedy and violence, our community responds with an open heart,” Warren  said. “Today as we mark 'One Boston Day' and the second anniversary of the attack at the Boston Marathon, we recall the strength and resilience that brought our city and our commonwealth together.”

Markey highlighted Boston’s response efforts, saying that the city had the “best training and personnel available” to help save lives in the wake of the bombings.

“We were Boston strong because we were Boston ready, with the best training and personnel available to save lives and to seek justice,” he said, adding that One Boston Day should be “an example of how our nation responds to times of crisis.”

Dzhokhar Tsarnaev was found guilty last week of 30 counts of federal charges tied to the bombing and a subsequent manhunt. The bombings left three people dead, and an additional 260 people injured.

The sentencing phase of the trial could start next week, and Tsarnaev faces a possible death sentence.

Warren called the guilty verdict “another step toward justice for victims and for their families.”
