Medical examiner's report has been released. It says that George Floyd had two forms of heart disease, was on fentanyl and had evidence of recent methamphetamine use. It lists the cause of death as cardiac arrest complicated by neck compression.
To put things into perspective.
Artherosclerosis found on autopsy means nearly nothing. Virtually 100% of all of us would have artherosclerosis if you do an autopsy. In fact, autopsy of infants and even fetus might show this as well. I had a profesor of pathology that have made the claim that 100% of newborns have it but I don't have the evidence to back that up. The point is, diseases are an spectrum and what you find on an autopsy might not necessarily have any kind of clinical significance. Same deal with hypertensive heart disease. The degree of severity matters more than the fact that they find evidence of that, after all, chances are we all have evidence of a bizzillion different issues.
As for fentanyl, it is highly unlikely that it had any, ANY play in this. The mechanism of death for opiods is respiratory depression and patient just stops breathing because of this. Now, for anyone to suffer from respiratory depression and cardiopulmonary arrest as a result of an opiod overdose they would have to first be unconcious. You don't lose your drive to breath before you lose your conciousness... it simply doesnt happen. The guy was talking and screaming and supposedly "resisting" arrest. Hardly someone that you can reasonably claim ODed on opiods. That wouldn't be a contributor.
Amphetamines could potentially cause arrhythmias and elevation of BP, in rare cases it could lead to death via various mechanisms (cardiac, strokes, etc). Keep in mind this is rare. Amphetamines is what we use for children with attention deficit disorder... The caveat is that you cannot compare pharmaceutical grade drugs vs something someone might have grabbed from the street that who knows what they might have. Furthermore, it might be hard to prove the time of ingestion/use of any of this. It is highly unlikely that they played a major role, or a role at all in this case.
Just to chime in for general education purposes
. Like I have said countless times, I don't think any of these makes a big difference, maybe during trial it might be a hot potato to try to convince the jury but other than that it does not weight in the facts.
I don't know, the knee on the back of the neck thing appears to be a generic submission hold. A man who did not have two heart conditions while on fentanyl would presumably not have died from it.
Two heart conditions that are ubiquitous and that at least 100% will show evidence of one of them (atherosclerosis) if we did autopsies on ourselves. I think your statement is misleading and/or misinformed.
