Several reports after the Boston Marathon bombings said they thought the Tsarnaev brothers acted alone.
But Representative Mike Rogers from Michigan is the chairman of the House Intelligence Committee isn’t sure.
Rogers clams there are “clearly more persons of interest” in the bombings and he didn’t stop there.
“I hear a lot of definitive statements out there that it was just these two men and it’s over, but I will tell you I hear these briefings every day, and I don’t think this is over” he told the Boston Globe.
Rogers went further saying “there are clearly more persons of interest, and they’re not 100 percent sure if there aren’t other explosives.”
A report in the Wall Street Journal on Friday said the brothers more than likely had had “additional training or expertise.”
On Friday news came from investigators that they think the bombs were set off by a remote control and were line of sight.
Because that type of device has a range that is typically less than 250 yards leads them to believe another person may have been involved.
