Investigators are pleading for help in hunting down whoever triggered a pair of bombings that left a gruesome scene at the Boston Marathon.
The blasts, which killed an 8-year-old boy and two others, marked a grotesque end to what should have been a celebration of triumph.
One man’s legs were instantly blown off, yet he kept trying to stand up.
Exhausted marathoners had to muscle the energy to flee the bloody scene.
And more than 140 people were hospitalized, some in critical condition.
“No piece of information or detail is too small,” the FBI Boston Division said, asking the public for any information or images that might provide clues.
While authorities search for answers, many are at a loss to explain why anyone would target the annual event that celebrates thousands of runners from around the world.
