Stick with the lethal levels of fentanyl along with heroin.
It does seem that Floyd ingested the fentanyl shortly before death. The time line is important here. When was the blood sample taken, how long after he was arrested. Orally it would take about 30-60 minutes to peak I believe. I don’t know if Floyd was with anyone before arrested.
The heroin is usually snorted or injected and peaks much faster less than 10 minutes. Heroin is rapidly metabolized to monacetyl morphine within a couple of hours. After that it goes to straight morphine,
Exactly. Establish doubt about culpability and he walks.
