Three days after the FBI released images of two men walking away from the scene that left over 20 injured in the suburb of Chelsea, Manhattan, no one has come forward with any information. Investigators say the two men picked up a suit case form the scene that contained one of the improvised explosive devices used by Ahmad Rahimi to kill Americans.
The men apparently saw the abandoned suitcase on 27th Street and found the pressure cooker inside that had been fashioned into a bomb. They set the device on the sidewalk and left with the suitcase.
One possibility that investigators have proposed is that the men were tourists, and may have already left the country.
