Authorities pursuing a suspect in the Boston Marathon bombing have a love-hate relationship with social media. After initially asking for help via Twitter, law enforcement later requested that social-media users be a little more conscientious about the kind of information shared (or fabricated) on social networks.

In the immediate aftermath of the dual blasts that killed three and injured dozens near the marathon finish line on Monday, law enforcement turned to the public via Twitter and other platforms for help crowdsourcing leads. On Thursday, the FBI released video footage of two young men carrying backpacks near the finish line of … Read more

The FBI has undertaken what is law enforcement's highest-profile effort at crowdsourcing to date: asking for help identifying two suspects linked to this week's Boston Marathon bombing.

"Someone out there knows these individuals," Richard DesLauriers, the special agent in charge of the FBI's Boston field office, told reporters this afternoon. He asked the media and the public for help in "identifying and locating these individuals."

The photos published on the FBI's Web site show two men, one wearing a black baseball cap and carrying a backpack, and the other wearing a white baseball cap, around the scene of the blasts. … Read more

As the search continued Wednesday for clues as to the person or persons behind the Boston Marathon bombings, hypothetical suspects and crime scenarios began popping up via online crowdsourcing.

After 24 hours passed without an arrest in the attack, the Federal Bureau of Investigations said Tuesday that the "range of suspects and motive remains wide open" and asked the public to submit photos, videos or anything suspicious that they may have seen or heard.

Members of the link-sharing community Reddit launched a sub-section called "findbostonbombers" late Tuesday to collect clues.

"Sometimes the rules change. Sometimes dogma needs to be flipped: 'Shut up and let the cops do their job' in the case of a terrorist attack is exactly wrong," Jason Calacanis, Internet entrepreneur, said in a blog post. Calacanis suggests that investigators should be combing through services like Twitter and video-sharing app Vine for clues.

Reddit users targeted at least three men, based purely on speculation. A link posted from photos-sharing site Imgur showed photos of the men collected on the Web site 4chan. … Read more

I had a friend running in the Boston Marathon yesterday. Her husband was waiting for her at the finish. When I found out they were both safe, I felt relieved, but still numb.

Others in Boston weren't so fortunate as my friends. They lost so much in such a senseless, awful manner.

Many onlookers around the world went to the natural social place to express themselves: Twitter. Could they add anything? Doubtful. Could they make anything better? Probably not, other than to offer their respect for and solidarity with those who so needlessly suffered and those who risked their … Read more

One of the runners in yesterday's Boston Marathon captured some sobering video footage from a head-mounted cam as the first of two bombs went off.

As Boston grapples with the aftermath of two explosions that hit the city during its annual marathon, YouTube has created a way for people to immediately get the latest news.

The video steaming site has built an official YouTube Spotlight page devoted to all video related to the blasts. Titled "Explosions at the Boston Marathon," the page has 26 videos as of this writing -- from President Barack Obama's speech to videos captured by onlookers to police press conferences detailing the explosions. More videos will surely be added as more is uncovered about what happened.

In the wake of today's deadly twin bombings at the Boston Marathon's finish line, the Boston Police has turned to Twitter to disseminate information and gather potential evidence.

Not long after the explosions killed two and injured dozens, the Boston Police Department's official Twitter feed was devoted to information about the attacks, including giving frequent updates on casualty and injury counts and asking people not to congregate in large crowds.

The police also used its feed to allay fears that an incident at the John F. Kennedy Library in south Boston was related to the marathon explosions. … Read more
