Martin, Lu, Krystle: Boston Marathon Bombing Victims Remembered

BOSTON — The triumph of the human spirit is a hallmark of the Boston Marathon. Six years ago, it was tested in the face of tragedy — and shined through in Carlos Arredondo, Jeff Bauman, Bruce Mendelsohn, Joe Andruzzi, Natalie Stavas and countless others whose stories, while anonymous, are no less courageous.

The 2013 Boston Marathon bombings claimed the lives of 8-year-old Martin Richard, 29-year-old Krystle Campbell and 23-year-old Lu Lingzi and injured more than 140 others. The pain and suffering caused by the attacks didn't end there — days later, MIT police officer Sean Collier, 27, was shot and killed during a manhunt for the bombers, and Boston police officer Dennis Simmonds, 28, died almost a year after he was hit by shrapnel while exchanging gunfire with the attackers.

One Boston Day was founded in the wake of the attacks to remember the victims through selflessness and love. The celebration of random acts of kindness, big and small, takes place on April 15, the anniversary of the bombings.

This year Marathon Monday and One Boston Day landed on the same day for the first time. The Red Sox held a moment of silence before Monday's game against the Baltimore Orioles, and the bells rang at the Old South Church at 2:49 p.m. to mark the time of the bombings.

Boston Marathon organizers released this statement:

There were no major security incidents at this year's marathon. A girl went missing near the finish line but she was found safe minutes later and foul play was not suspected.
