(NBC News) Authorities investigating the attack on the Boston Marathon focused Thursday on finding two men seen on camera, including one who set down a black bag and dashed away just before the bombs went off.
According to the report from NBC News:
Investigators combed cellphone records in an effort to put a name to the men’s faces. Law enforcement officials said that they were seen from several angles, including from a surveillance camera at a department store, and that one was seen talking on a cellphone.
After receiving a staggering amount of videos and pictures, investigators are pursuing some promising leads, including images from several sources showing someone carrying a heavy duffle bag and placing it at the spot where the bombs went off.
The FBI distributed a photo to other federal law enforcement agencies of the men.
The official described one of the men in the photo as about 6 feet tall and wearing a baseball cap that was white or off-white. He was spotted at the site of the second of the two blasts, which combined killed three people and hurt 176 near the marathon finish line Monday.
Investigators still had no conclusion about whether the attack was foreign or domestic terrorism.
Authorities were weighing whether to release photos of the men. Doing so could help the probe but could also generate misleading tips, and investigators want to pursue their existing leads before appealing to the public for help.
