Reddit user caindaddy uploaded an image of suspect no. 2, identified as Dzhokhar A. Tsarnaev, from the photo provided by the FBI.

Reddit user MelGibsonDerp posted a picture of what he believed to be one of the suspects near a backpack on the ground and what appeared to be an image of Martin Richard, the 8-year-old victim of the bomb explosion at the marathon.

Reddit user deathmagos uploaded an image of what appeared to be a Facebook page of Dzhokhar A. Tsarnaev, showing he updated it Friday morning. It's unclear whether the image is accurate.

Reddit user mrderk might not have been the first but the user posted an image of a photo essay titled “Will Box For Passport,” from a photographer named Johannes Hirn. It appears to feature Tamerlan Tsarnaev, the Boston Marathon bombing suspect who was killed in a police shooting out on Friday.

Reddit user curbsideaudio uploaded one of the boxing images of Tamerlan Tsarnaev.

A Reddit user upload an analysis of a crowd shot from the marathon, which may show victim Jeff Bauman standing next to one of the suspects. Bauman was the man shown in pictures in media outlets being wheeled away from the blast in a wheelchair, having lost his legs.

How Reddit Became A Hub Of The Crowdsourced Boston Marathon Bombing Investigation

Reddit's users launched a new subreddit, Findbostonbombers, where hundreds of amateur sleuths are crowdsourcing clues and suspects in the Boston terrorist attack.

In an inevitable development, Reddit users have begun crowdsourcing an investigation into the Boston terrorist attack. A new subreddit called Findbostonbombers had over 870 subscribers and 1,600 visitors on Tuesday, April 16 who were analyzing photos, parsing through video, and conducting third-party forensic analysis of the Boston Marathon attack independent of law enforcement. Commenters and contributors to the subreddit are posting a mixture of useful analysis, misguided amateurism, and racist or anti-gun activist invective.

Many users on the site are focusing on a man they call ”Blue Robe Guy,” spotted in the crowd carrying a backpack identical to one of the black bags investigators say was used to hide one of the pressure cooker bombs. Both bags have identical shoulder stripe markings. Other users are organizing collections of mass photo dumps in order to sort through any photographs of the attack found for possible clues.

While amateur sleuthing is fun, motivations behind the crowdsourcing can be questioned. As The Awl's Choire Sicha noted, some of the posts in the subreddit are bigoted or simply bizarre. Reddit users looking for Islamist terrorists can, for instance, say “I hate to even bring up this point, but when I have seen videos of radical Islamists yelling 'allahu akbar' in the past, I seem to recall seeing them make something like the pinched thumb and forefingers gesture he is making in the second picture.” In addition, Reddit users are identifying potential suspects with potentially life-ruining consequences. There is always the risk of a crowdsourced Richard Jewell—that is, the risk of an innocent person being unfairly accused of a horrific terrorist attack by the subreddit in a meme that spreads across the Internet.

The problem with doubting and sneering at the Reddit users cracking the case, however, is that crowdsourcing criminal investigations sometimes does work. In one noteworthy case, commenters on Gawker and New York's Daily Intelligencer succesfully identified Aidan Folan, a 21-year-old Brooklynite suspected of mugging and assaulting an elderly woman in a horrific subway station attack. Folan was subsequently charged with robbery and assault; the NYPD had failed to track Folan down in the three weeks following the mugging, but blog commenters identified and located him within minutes.

In the meantime, even the FBI is embracing crowdsourcing of sorts: The law enforcement agency is requesting that anyone with photos or video of the Boston Marathon contact them. While crowdsourcing did crack the suspected Folan case, it's important to note the magnitude of difference between the two crimes. The subway mugging was a horrific crime that, nonetheless, was a local news story and apparently not a priority for the NYPD. On the other hand, the Boston terrorist attack is an international news story that disrupted one of the world's best known sporting events. It's amazing how law enforcement resources can be reallocated when the case is big enough.

Update: The FBI has identified the two suspects as Dzhokar and Tamerlan Tsarnaev, two Chechen brothers living in the Boston area.

Reddit users apparently discovered the pair in numerous photographs on the /findbostonbombers subreddit. The suspects, identified by their distinctive hats, were flagged by Reddit users in threads such as Two Photos of White Hat after Forum Explosion and New picture of suspect 2.

A data dump about Tamerlan Tsarnav, an amateur boxer, , says that the 26-year-old was the subject of a photography project several years ago and had a YouTube profile with a playlist dedicated to terrorism.

Dzhokar is currently at large, and Tamerlan Tsarnaev died overnight in a confrontation with police.

Boston Police Take Suspect Into Custody, Alive. Subreddit Findbostonbombers Shut Down

3:30 p.m., 04/19/2013

Reddit, The Lynch Mob, And The Known Unknowns

One of the biggest ramifications of the Reddit crowdsourcing effort, as I discussed earlier, was the incorrect identification of suspects. For all of the benign intent shown by (most) members of the Reddit community, they were still amateurs conducting a terrorism investigation in an extremely public forum. In a deleted thread on a non-terrorism investigation-related subreddit, users speculated that a missing Brown University student was a terror suspect. Someone, either trolling on Twitter or not understanding a police communication, said that student was named as the second bomber over a police scanner. That wasn't the case. This student was named, and his family was harassed in short order. A family with a missing child was harassed by unknown internet users who thought they were doing good, all because of the crowdsourced investigation.

Benjamin Levine, the Boston man whose photograph was recycled for a controversial New York Post cover, emailed me with an interesting take on things:

"My pictures were used to thrust blame on people who had absolutely nothing to do with the tragedy. One notable examples of this was the New York Post's front page on April 18. The Post asked for my permission to use my photos. Instead of asking for more information on how they intended to use them, I blindly gave them permission. This was a mistake and led to them using my pictures to suggest that a high-schooler played a part in the bombings. They did this even after he was apparently acquitted of any charges of involvement. I am so sorry for the part that I played in ruining this boy's life. I want nothing more than to apologize to his face."

"I've been trying hard not to judge the "sleuths" on Reddit who have been dissecting my photographs and others to try and find clues. I think that a vast majority are people just trying to help out. So many people have been trying to help out in many ways and Boston is so thankful for that."

"Also, I'm sure some of the people who have been on Reddit were in a position similar to mine. Some were probably much closer to the bombs and are far more shaken than me. Some who didn't take pictures may be using mine to help themselves cope. I hope that they can help at least one person in what is undoubtedly going to be a long process for many of us."

"One thing that does worry me is that a few "sleuths" on Reddit may be using this as an opportunity to have a little fun playing detective. People deal with tragedy in different ways, and its hard to fault people for getting by in their own way, but I can't bear to look at the threads on Reddit."

Meanwhile, the million dollar question everyone is asking—but noone can answer at this junction—is how much actual law enforcement investigations leveraged from the crowdsourced Reddit and 4chan efforts. Were law enforcement officials scouring Reddit for leads, alternate approaches, or verification? We won't know the answer for quite a while, but it's hard to believe the FBI or Massachusetts State Police weren't sneaking quick looks at either site.

Man Whose Photo The New York Post Used To Wrongly Identify Suspects Speaks About Reddit's Wrath

When the New York Post published a front page cover featuring two innocent men they implied were the Boston terrorists, it was a journalism fail. Although the Post said the photos were being distributed by “law enforcement authorities,” they were obtained through a distinctly 2013 brand of social and digital media.

The photo was taken by Benjamin Levine, a 24-year-old Bostonian whose office at Marlo Marketing & Communications overlooked one of the bomb sites. His firm was hosting a marathon party and he was taking photographs when the bomb went off. Levine sent several pictures to Deadspin and wrote a firsthand account after the terror attack; he told Fast Company that his firm encouraged employees to blog as a therapeutic exercise.

Levine sent photographs to the Federal Bureau of Investigation shortly after law enforcement requested photos and videos from bystanders. Shortly after the photos went up on Deadspin, they became the subject of fevered speculation on Reddit and 4chan, which also hosted a crowdsourced crimesolving effort. Major newspapers then reached out to Levine asking for permission to republish his photograph. When Levine saw a cropped and enhanced version of his photograph on the cover of the Post, he was mortified.

“I was outraged at the stupidity,” Levine said in a telephone conversation. “I asked them to use (the picture) respectfully and it wasn't at all, even though I knew of the Post's reputation.”

When Levine's photographs jumped from Deadspin to the larger Internet, he was taken aback but understood the impulses behind crowdsourced anti-terrorism forensics. “I had anger—honestly, people deal with things in different ways,” Levine said. “I try not to be angry at people on Reddit, but it seems like people enjoy playing detective for the day, and it gives them an escape—it has been a struggle for me not to judge.”

What Reddit Got Wrong

While Reddit's thousands of amateur sleuths got a lot of things right, they also got a lot of things wrong. Earlier in this article, we referred to a “Blue Robe Guy” who Redditors speculated was connected to the terrorist attack.

Like many other threads posted on the subreddit, the discussion of Blue Robe Guy was removed from the site. The subreddit's creator, a 23-year-old professional poker player from England calling himself Oops777, told Buzzfeed's John Herrman that the worst case scenario was “we waste our time,” but more than a dozen other potential suspects were flagged by Redditors. These posts were then taken offline in an attempt to eliminate confusion among users. With that said, Reddit users were crowdsourcing a violent attack and tentatively photo identifying suspected terrorists on a public forum accessible by anyone. As we all know, no one on the Internet ever jumps to conclusions or ever acts impulsively.

The only problem is that Reddit users weren't the only ones jumping the gun. Mainstream media institutions were just as bad; the New York Post famously put a picture on their front page of two men they implied were suspects; the two men were not suspects and just happened to be spectators of Middle Eastern descent. CNN mistakenly claimed a suspect was in custody when there wasn't one. Sometimes established institutions jump to the same hasty conclusions as the crowdsourced mobs of the Internet.

The Growth Of Subreddit "Findbostonbombers"

Inside Reddit's user community, an enthusiastic amateur forensics subculture grew exponentially once the subreddit was formed. When Fast Company reported on the subreddit's existence at the beginning of the week, it had approximately 870 subscribers; more than 9,000 Redddit users now patronize the site. The hunt for the Boston bombers on Reddit appears to have been the Internet's largest crowdsourced crime-solving exercise to date—regardless of law enforcement's feelings about it.

Despite the presence of racist and anti-right wing trolls, Reddit users did find a number of important clues (and publicized a number of false leads to the detriments of others, but that is something we will return to in a bit). Sleuths on Reddit identified the hat worn by one of the bombers; the same thread also featured the highest resolution pictures of one of the bombing suspects to date—which was flagged by Reddit users as potential evidence.

A Crowdsourced Investigation

In a new indication of the meta atmosphere of reporting news in 2013, law enforcement authorities are asking Twitter users not to tweet any information about stakeouts, manhunts, or tactical operations being used to catch Tsarnaev. Law enforcement operations are currently in place in suburban Boston, one of the world's most wired—and most social media-loving locales.

Continuing the unusual social media happenings surrounding the events, NPR personality Robin Young went to Twitter to express her shock that her nephew was friends with Djohar Tsarnaev. Young even posted a high school graduation picture of her nephew and him, along with a tweet saying "he came to the prom party we had. beautiful boy."

Jeff Bauman, Who Lost His Legs, Aids Law Enforcement

Users on Reddit have discovered pictures that apparently show one of the suspects standing next to Jeff Bauman. Bauman was the Marathon bystander in an iconic photograph that showed him being wheeled away by Carlos Arredondo after losing both legs. Bauman is currently playing a critical role for law enforcement. Bloomberg reports that Bauman saw the bomber and spoke with authorities, giving critical clues as he was prepped for emergency surgery. The photographs on Reddit appear to clearly show both Tsarnaev and Bauman.

     Uh no. They got it terribly terribly wrong. In fact most were 'certain' it was the missing student that was the culprit and harrassed the family so much that they had to take down their Facebook page.

  • ARRRGGGHH

    Aaaaandd that's the death of crowdsourced investigations. Just ask the falsely accused whose lives have been permanently damaged. Welcome to 21st century mobs, the same kind that the Founders warned against.

  • anonymous

    Maybe you should post about all the people who Reddit incorrectly fingered? 

    They did literally nothing to help in this case, and left behind a wake of innocent victims.

    They should be places that act as data dumps, and they should be working to clear people, not indict them. Authorities don't need help finding people to accuse. 

  • Neal Ungerleider

    Absolutely, and we'll be writing about it soon. As a journalist examining a massive crowdsourced crime solving project, one thing that alarms me is how investigative work is taking place in public--with a distinct lack of private messages and off-record brainstorming. That's something we're looking at.

  • Brandon A. Smith

    Good angle, FC. I personally think it's a good thing that people are wanting to get involved like this. I know specific instances where crowdsourcing an investigation on Jalopnik has solved crimes. If it helps in the investigation, great. The biggest thing crowdsourcing something like this does is open our eyes to new ways to look at things that otherwise would not have been seen. And talking about the bad that people could do—they are behind their computers working this out, not out in the field with guns-a-blazing. (Let's hope that's not the case.)

  • antediluvian

    Wow...what could possibly go wrong with this? Oh I don't know...maybe an internet-fueled wave of vigilante "justice" that points at innocent people.

    Seriously, just because you have an internet connection doesn't make you a crime fighting detective....no matter how many episodes of CSI you've watched.

  • RottenLoudmouth

    Oh, like that time the Atlanta Olympics were bombed, and the internet fueled a wave of vigilante justice that resulted in an innocent man being investigated for the crime and having his life utterly destroyed thourgh the media, only later we found out that everyone was wrong? Oh, wait, it was the professional crimefighters at the FBI who did that…

  • Tyler Fastcompany Gray

    A pretty succinct summary of both sides of the argument, right there--which is precisely why we're following this particular angle in this way. We don't know how it's going to shake out, whether having amateurs involved in sleuthing will ultimately be a good or bad thing. But it's becoming a part of these kinds of huge crime events.
