Social media has created a bit of a conspiracy about the culprit of the Boston Marathon bombs.
Did you see this Monday? A person on the roof of a building at the time of the explosions?
Dan Lampariello, a college student, took the photo.
Many across Twitter, Facebook and Instagram are asking if this could be the person responsible for the horrible attacks that killed three and injured more than 100 people.
Officials have not said anything about this person, if they could be involved or not and who it might be.
