Now…For the work of finding out who is responsible for this. It is impossible to say at this time whether this is an act of Foreign or Domestic Terrorism. At least to reports at this time, the bombs appear to have been relatively crude devices made from either home made or cobbled together explosives wrapped in nails and screws to function as shrapnel, which suggests they were made with off-the-shelf materials purchased here in the United States. There is still confusion on whether there were more bombs.
Yet another tragedy.
