The toxicologist’s testimony challenged Derek Chauvin’s attorneys’ claims that George Floyd had overdosed on fentanyl.



Forensic toxicologists in the laboratory that performed George Floyd’s blood tests said it was common for fentany-based intoxicating driving suspects to have higher systemic drug levels than Mr. Floyd did it when he died. Prosecutors hope his testimony will touch Derek Chauvin’s attorneys arguments that Mr Floyd’s death may have been a drug overdose.

Toxicologist Dr. Daniel Isenschmid worked at NMS Labs in Pennsylvania and testified on the ninth day of his trial against Mr Chauvin, who was charged with the murder of Mr. Floyd’s death of more than 2,300 blood samples from drivers at The intoxication that NMS Labs tested last year ̵

1; all of which were cases where drivers survived and tested positive for fentanyl – about a quarter of people had the same or higher fentanyl levels. Isenschmid said.

Prosecutors called him to the stand to contend arguments from Mr Chaowin’s attorneys that fentanil, the powerful opioid drug, had caused Mr Floyd to overdose. Prosecutors said Chua Win was responsible for Mr Floyd’s death, and earlier on Thursday, pulmonologists testified that Chua Win’s knees on Mr Floyd’s neck and back were key factors. In his death

Dr Eisenschmid said that last year, in the case of NMS Labs blood tests on deaths and fentanyin people, the average amount found by the scientists was 16.8 nanograms per milliliter, which is higher than the amount found in Mr. Floyd is about 50 percent blood. But Eric J. Nelson, a lawyer for Chauvin, says the average is among people who die of any cause and have fentanyl in their system, not just an overdose. And he pointed out that the median level of fentanyl in that group was slightly lower than that of Mr. Floyd.

The testimony of Dr. Eisenschmid, who previously worked as chief toxicologist at Wayne County Medical Examiners’ office in Detroit, is at his best. But the jury looked attentive, according to reporters in the courtroom.

He said that while the human body processes fentanyl, it turns out to be norfentanyin and that Floyd has a relatively high proportion of norfentanyl, indicating that the body of He has processed several parts of the fentanyil. That is in support of prosecutors’ arguments that Mr Floyd did not overdose. A fentanyl overdose usually occurs shortly after taking a medicine, before a person’s body breaks down much of the drug.

But Dr. Eisenschmid admitted in Mr Nelson’s response that it was possible Mr Floyd captured and processed fentanyl earlier in the day and then spent more time on the Moments before or during the seizure Toxicological results Isenschmid said it did not specify when specific doses of fentanyl were used.

Mr Nelson had pointed out that pills with Mr Floyd’s DNA in them and possibly partially eaten were found in the back of a police car where Mr Floyd was briefly placed.

Isenschmid said the same amount of fentanyl could have a very different effect on new users compared to people with the drug. Mr Floyd’s boyfriend said she and Mr Floyd were both trying to stop using Opioids.

“If people can tolerate drugs, they need more and more to achieve the desired effects,” said Dr. Eisenschmid.

Methamphetamine was also found in Mr. Floyd’s system. Eisenschmid said the levels were so low they likely had no intoxicating effect.
