Agreed, and the toxicology report can come back with the presence of a recreational drug that is out of character for their use, masking the reality that they thought they were taking a different drug to begin with, while all options could have been tainted with fentanyl
Or nothing at all.
Or there was foul play.
Or there was foul play without the use of drugs.
Or fentanyl use was intentional.
Hoping to rule somethings out!
