The arsenal found with the surviving Boston Marathon bombing suspect upon his arrest Friday included at least four firearms, one of which was an M-4 carbine rifle, a weapon similar to ones used by American forces in Afghanistan, the Times reported Sunday. Together, the Tsarnaev brothers fired about 80 rounds in a shootout with police officers, yet it appears neither brother was licensed to carry firearms.

“The younger brother could not have applied as he is not 21 years of age, and the older brother did not have a license to carry and we have no record of him ever applying,” said a Cambridge Police Department spokesperson.
