The trial of former officer Derek Chauvin will continue on Thursday after a day of testimony focused on Mr Floyd's drug use on the day of his death. Mr. Chauvin's defense has tried to argue that Mr. Floyd died of a possible overdose, but the prosecution blames the actions of Mr. Chauvin, who held Mr. Floyd with his knee for about nine and a half minutes.
Here are some key takeaways for Day 9 of the trial.
An expert said there was no need for violence once Mr. Floyd was suppressed.
An expert on the use of violence, Sgt. Jody Stiger, who works at the Los Angeles Police Department's Office of the Inspector General, testified that "no force should have been used" when Mr. Floyd was subdued, handcuffed and lying face down on the sidewalk. The Sergeant also said that Mr. Chauvin put Mr. Floyd at risk of positional asphyxiation or oxygen starvation.
"He was prone, he was handcuffed, he wasn't trying to resist, he wasn't trying to attack the officers – kick, punch or anything like that," Sergeant Stiger told prosecutors.
In response to questions from the defense, Sergeant Stiger said Mr. Floyd opposed arrest when officers tried to put him in the back of a police car. At the time, Mr. Chauvin would have rightly used a Taser, Sergeant Stiger said.
There were conflicting testimonies about Mr. Floyd's drug use.
Senior Special Agent James D. Reyerson of the. Asked to interpret images from a police agency camera The Minnesota Bureau of Criminal Apprehension initially said that Mr. Floyd appeared to be saying, "I ate too many drugs." But in later testimony, Mr. Reyerson changed his assessment and said Mr. Floyd had actually shouted, "I don't use drugs."
His revised judgment could challenge the defense of Mr. Chauvin, who has tried to argue that Mr. Floyd died of complications from drug use, not Mr. Chauvin's actions. A toxicology report found methamphetamine and fentanyl in Mr. Floyd's system.
Pill fragments containing Mr. Floyd's DNA were found in a police car.
McKenzie Anderson, a forensic scientist with the Minnesota Bureau of Criminal Apprehension, processed the police car that briefly housed Mr. Floyd the night he died. An initial treatment did not find drugs in the vehicle, she said, but during a second search at the request of Mr. Chauvin in January, the team discovered fragments of pills containing DNA that matched Mr. Floyd.
Breahna Giles, another forensic scientist with the Minnesota Bureau of Criminal Apprehension, testified that some of the pills found on the spot were tested and found to contain methamphetamine and fentanyl. They were marked with letters and numbers indicating pharmaceutical grade acetaminophen and oxycodone, although illegal pills are sometimes marked by drug dealers to give the false impression that they are from a pharmacy.
