The FBI is scrutinizing two sets of images that may help them find the person or people who planted two deadly bombs at the Boston Marathon finish line on Monday.

One, from Boston television station WHDH, shows a bag in front of the security fence which appears to be at the center of one of the explosions.

The other images come from office worker Ben Thorndike, whose office window was right above one of the blasts.

He told ABC News that pictures he took from that window show a man dressed in black, who - unlike everyone else - is running away from the middle of the commotion.

The FBI has not said whether the man or anyone else is a suspect in the bombings.
