An image taken of the second explosion at the Boston Marathon has led many in the blogosphere to jump to conclusions and conspiracy theories.
In the photo, a single, shadowy man atop a rooftop can be seen lurking over the race, watching from above.
The photo is credited to Suffolk University junior Dan Lampariello. The photo, taken the same instant as the second explosion, went viral and was broadcast on all major television stations such as CNN, ABC and CBS, according to The Christian Science Monitor.
"I was about 200 feet from the finish line ... right in front of the Mandarin Hotel," Lampariello said. "My aunt was actually running in the marathon. We were out there to cheer her on. We thought maybe it was fireworks at first, but when we saw the second explosion we definitely knew that something was wrong."
The explosion killed three people, including 8 year-old Martin Richard, who was cheering for his father at the finish line. He was waiting with his mom and 6 year-old sister, who suffered serious injuries and are currently in the hospital, according to MSN.
He has been the only victim identified as of yet. A single candle was lit in front of his house last night with "Peace" written beside it on the sidewalk.
Even though the mysterious man had yet to be identified or listed as a possible suspect, many people across the Internet are speculating. The man may have simply been one of many watching the race from a rooftop.
"On Monday night agents from the FBI, the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), and other law enforcement agencies raided a unit in a high-rise apartment on Ocean Drive in the seaside Boston suburb of Revere, according to information posted online by a participating local fire department," The Christian Science Monitor reported. "Several bags, including what appeared to be a large duffel bag, were removed from the scene. Authorities were mum as to the specifics of their suspicions but confirmed that the Revere search was related to the case."
Police are also asking citizens to send in any photos or videos they have of the event according to NBC.
"There has to be hundreds, if not thousands, of photographs, videos and other observations that were made down at that finish line yesterday," Timothy Alben, superintendent of the Massachusetts State Police said. "You might not think it's significant, but it might have some value to this investigation."
