Boston Marathon Suspect 1

The FBI released Thursday 11 photos and a video of two young-looking suspects on Monday's Boston Marathon bombings, where three people lost their lives and close to 170 were injured. 

Authorities identified the two suspects as "suspect 1" and "suspect 2," as they showed still and moving images of the two young-looking men wearing casual clothes and sport hats as they walked among the crowd. 

As soon as the FBI released the photos, social media users started speculating about the individuals' race — a politically charged variable as it'll likely frame the remaining of the investigation along the lines of either "domestic" or "foreign" terrorism.
