One thought I had in reference to the DNA on a presser cooker bomb is that there was a bomb at the site of the shoot out as well. I wondered if the DNA was on that one. jmo
I wonder that too.
All sorts of DNA and prints could be on the damaged bits of the ones at the marathon, and defense attorneys would be all over that. But, if it is the bomb at the shoot out, only the brothers' DNA and prints should be on it.
These 3 students have no idea how bad a Federal Criminal Record is. Can't believe they through away evidence in a murder/terrorist case. Wow. If convicted, life in the U.S. will not be as pleasant as far as job or career, or later in things such as adoption, or anything that requires a criminal background check.
