One question for the FBI: why so much investigation over a crime committed by someone who is dead?<p>Based on the nature of the crime, I&#x27;m guessing there weren&#x27;t many accomplices.  The one guy who helped him get the guns is probably where they need to be focusing their investigation and interrogation. If ISIS helped him, how?  He took a gun to work and killed people. That&#x27;s not an elaborate scheme.<p>It does not benefit the FBI to lose goodwill with the American people over this case.
