Two bomb blasts, 12 seconds apart, rocked the finish line of the 117th running of the Boston Marathon Monday, killing at least three people, including an 8-year-old Dorchester boy, wounding more than 130, and leaving the sidewalks of Boylston Street covered in blood.
Medical professionals on hand to care for blisters and sore knees in Copley Square suddenly found themselves treating life-threatening lacerations and lost limbs, as a high holiday in Boston, Patriots Day, turned into an epic tragedy.
Emergency workers rushed to the scene, despite the very real possibility of more blasts.
The explosions blew out windows, sent plumes of smoke into the sky, and left victims piled on each other in a scene far more reminiscent of a battlefield than a celebrated day in Boston’s Back Bay.
The blasts occurred at 2:50 p.m., several hours after the elite runners had finished the race.
About 30 people were transferred to hospitals under a Code Red, meaning life-threatening injuries, which may point to a rising death toll, said a law enforcement official.
