The anniversary of the Boston Marathon bombings promises to be a day of tributes to the three people who died, the more than 260 people who were hurt, and the first responders, doctors and nurses who helped them.
Vice President Joe Biden, Gov. Deval Patrick and former Mayor Tom Menino are among the dignitaries expected to speak Tuesday during a program at the Hynes Convention Center. Survivors of the bombing also will participate.
Between 2:30 p.m. and 3 p.m., a flag-raising ceremony and moment of silence will be held at the marathon finish line, to mark the time and place where two bombs exploded on April 15, 2013.
Authorities say two brothers planned and orchestrated the attack. Tamerlan Tsarnaev died following a shootout with police. Dzhokhar Tsarnaev is awaiting trial.
