You won’t.
“...The medical examiner, Dr. Joshua Stephany, said the autopsies did not make any determination as to who killed whom....”
Speechless if he means determining the source of each bullet was not and will not be done.
I hope what he meant was that the autopsy itself does not establish guilt, it only collects evidence.
Yeah, there are just too darned many bullet holes to be really concerned with who fired each one and exactly who killed who.
We dont have to re-adjust our narrative this way, and it will just save a lot of embarrassment later on in the case.
An autopsy would focus on documenting trauma to the bodies, cause of death (small caliber gunshots to x, y, and z), and recovering the projectiles with a chain of custody. The ME isn’t in charge of the ballistics tests, or at this point, figuring out who shot whom in a mass shooting.
Other than hearsay, the ME has no way of knowing if some of the projectiles came from police weapons, or weapons of other terrorists yet unidentified.
