From your article:
...”was assaulted and died of blunt force trauma”
compare to:
...”died as a result of blunt force trauma AFTER being assaulted...”
More questions:
Was he alive/unconscious when put in the dumpster?
If he fought back did he have some DNA under his fingernails?
If just a street crime, why didn’t they just leave his body where it fell?
Why drive body several miles to the dumpster in another town?
Would location of assult point finger at the guilty party?
