The FBI recently released the video and photos of the Boston Marathon bombings suspects and they said that they are both armed and very dangerous. Anyone who knows and see them are encouraged to call authorities.
The 2 suspects are in their 20's and as you can see in the video one is wearing a dark colored cap and sunglasses while the other one is wearing a white cap that is turned backwards with no sunglasses and both carrying a backpack. They are walking together towards the finish line where people are waiting.
I hope these suspects will be apprehended.
