As the stunning photo of the hero in the cowboy hat aiding a critically injured man after the Boston Marathon blasts went viral, a concerned dad learned of his son's grim fate.

While Jeff Bauman tried reaching his son, also named Jeff, on Monday after the explosions, the distraught dad got a call from his stepdaughter asking if he had seen “the picture,” The New York Times reports. It was then that Bauman signed onto Facebook and saw a photo of his 27-year-old son's gruesome injuries.

Bauman and his wife drove from Concord, N.H. and reached Jeff’s bedside late Monday night, after both of his legs had been amputated at the knee, according to the Times. He had further surgery because of fluid in his abdomen, the Associated Press reported.

The image of the critically injured man who had gone to the marathon to see his girlfriend race has gained traction not just because of its gruesome nature. It also signifies just how much selfless heroism emerged in the face of one of the most heartless attacks on American soil.

As soon as Carlos Arredondo, a peace activist who came to the race to honor his two dead sons, saw just how hurt Jeff was, he tore away the snow fence and scaffolding and raced to his side, according to the Portland Press Herald.

Arredondo had been waiting at the finish line to cheer on the National Guard runners who were racing in honor of a number of fallen servicemen, including Arredondo’s son, Lance Cpl. Alexander S. Arredondo, who died at age 24 in a firefight in Iraq, ABC reports. The mourning dad was also there supporting Samaritans, a suicide awareness group. His other son, Brian, committed suicide in 2011 after years of battling depression after his brother died.

In the moment that a bomb claimed Jeff's legs, Arredondo raced into the carnage. The father who had lost his own two sons and quit his job to commit his life to protesting war said he didn’t hesitate for a moment. As another volunteer helped wheel Jeff away, Arredondo can be seen seemingly pinching closed a severed artery from Jeff's thigh.

"My first reaction was to run toward the people," he told ABC. "There was so much commotion and a lot of people running away. I was one of the first to help people and God protected me. It was horrific."

A massive probe was underway Tuesday after two bombs struck the Boston Marathon, killing at least three and wounding more than 100. Monday's blasts near the finishing line raised fears of a terrorist attack more than a decade after nearly 3,000 people were killed in suicide airliner strikes on New York, Washington and Pennsylvania on September 11, 2001. US President Barack Obama went on national television to warn against "jumping to conclusions" but a senior White House official, speaking on condition of anonymity, said such an attack was "clearly an act of terror."
