The chair of the U.S. Senate subcommittee on emerging national security threats said at a hearing in Washington that much has been learned about enhancing emergency responses since the 2013 Boston Marathon bombing, but more ca be done.

The 10th anniversary of the Boston Marathon bombing is being marked with a wreath laying at the finish line to remember those who were killed, a day of community service and an event for the public to gather to reflect on the tragedy.

The Biden administration will try to persuade the Supreme Court this week to reinstate the death penalty for convicted Boston Marathon bomber Dzhokhar Tsarnaev.

President Joe Biden’s administration is urging the U.S. Supreme Court to reinstate the death sentence for Boston Marathon bomber Dzhokhar Tsarnaev despite the president’s vocal opposition to capital punishment.

A suburban Boston police officer who became a national hero in 2013 when he tackled one of the Boston Marathon bombers has retired from the only job he ever wanted.

But President Donald Trump tweeted on Sunday that the federal government must again seek the Death Penalty in a do-over of that chapter of the original trial." Yet, victims and their family members have long been divided over the death penalty for Tsarnaev. Others infuriated by the appeals court's decision say they are prepared to face Tsarnaev in court again, if need be. Liz Norden, whose two sons who each lost a leg, also hopes prosecutors continue to go after the death penalty. "I just think if we dont follow through with the death penalty in this type of crime, what would fit it?"

A federal appeals court has overturned the death sentence of Dzhokhar Tsarnaev in the 2013 Boston Marathon bombing, Friday, July 31, 2020, saying the judge who oversaw the case didn't adequately screen jurors for potential biases. When it comes to death penalty cases, the U.S. Supreme Court has been much more pro-prosecution than many of the circuit courts, said Robert Dunham, executive director of the Death Penalty Information Center. Should Friday's ruling stand, attention will shift to whether an impartial jury can be impaneled in a city still traumatized by the 2013 attack. Tsarnaev's defense team may renew its request to transfer the case out of Boston, where they have long contended public opinion is immutably slanted. Everybody in the community understands where Boston Strong came from, Dunham said.

A federal appeals court Friday threw out Dzhokhar Tsarnaevs death sentence in the 2013 Boston Marathon bombing, saying the judge who oversaw the case did not adequately screen jurors for potential biases. A spokesperson for the U.S. Attorneys office in Boston said they were reviewing the opinion and had no immediate comment. Prosecutors could ask the full appeals court to hear the case or go straight to the U.S. Supreme Court. In a concurring opinion, Judge Juan Torruella wrote that the case should never have been tried in Boston. "I see in Boston, where you have the animal that killed so many people during the Boston Marathon, Trump said.

(CNN) - Details about a gruesome triple homicide at a Massachusetts residence in 2011 that a friend of Boston Marathon bomber Tamerlan Tsarnaev said they took part in were revealed this week in federal court documents. The documents were filed Wednesday in connection with a pending appeal by Dzhokhar Tsarnaev, Tamerlan's younger brother and Boston bombing co-conspirator, of his conviction and death sentence. The FBI and a Florida investigator each said the shooting was justified because Todashev allegedly tried to attack the FBI agent. The bombings sparked a manhunt that shut down the city for days and the brothers later killed a Massachusetts Institute of Technology police officer. Dzhokhar Tsarnaev was arrested a day later and convicted for his role in the bombings.
