The fourth day of testimony Thursday was highlighted by accounts from Chauvin's former supervisor, two paramedics, and George Floyd's girlfriend.
Nelson seemed to acknowledge the sensitivity when he stood up to cross-examine Ross: "I'm sorry to hear about your struggles with opioid addiction", he began.
However, prosecutor Matthew Frank tried to downplay the potential toxicity of those pills, getting Ross to agree that, obviously, neither she or Floyd had died from ingesting them in March or May.
"We both suffered from chronic pain", she said.
She said she thought Floyd sometimes bought pills from Morries Hall, who was sat in the auto next to Floyd in the front passenger seat when police arrived last May. Nonetheless, Ross emphasized the many times he had tried to quit his addiction.
Prosecutors put Ross on the stand as part of an effort to humanize Floyd in front of the jury and portray him as more than a crime statistic, and also apparently explain his drug use to the jurors and perhaps get them to empathize with what he went through. They have also said that his drug use overall is irrelevant to Chauvin's charges. Prosecutors say he knelt on Floyd's neck for 9 minutes, 29 seconds, pinning the handcuffed man to the ground.
The most serious charge against him carries up to 40 years in prison. An autopsy by the Hennepin County medical examiner found that Mr. Floyd had fentanyl and methamphetamine in his system when he died.
In the months that followed, Ross said, she and Floyd spent a lot of time together during the coronavirus quarantine, and Floyd was clean during that time.
In some of the video, Mr Floyd can be heard calling out, "Mama!" repeatedly and saying, "Mama, I love you!. Tell my kids I love them".
George Floyd's girlfriend smiled through tears as she told a jury on Thursday how they first met when he offered to pray with her, less than three years before his deadly arrest, and described how they both struggled with opioid addiction. "When they take selfies, it's kind of lower and it's just, they don't, I don't know, take the time to do the certain angles that everybody else does".
She said he had been hospitalized for an overdose in March. "I was sad and kind of mad", the little girl testified. It's something I'll deal with forever.
Ross also admitted that she was aware that Floyd had overdosed in March of past year and spent five days in the hospital.
She was waiting in the lobby to see the father of her son, exhausted after closing up the coffee shop where she worked.
"May I tell the story?" she asked. She said: "It's one of my favourite stories to tell".
Asked if she noticed any foam coming from his mouth when he was hospitalised in March, she said there was "some foam building on the corner of his mouth" and clarified it was some dry white substance.
"Do you have an opinion as to when the restraint of Mr. Floyd should have ended in this encounter?"
"Floyd has this great Southern voice, raspy". He was like, 'Sis, you OK, sis?'
"It's been nights, I stayed up apologizing and apologized to George Floyd for not doing more, and not physically interacting, and not saving his life", Darnella Frazier, the teen who recorded the video of Floyd's death that went viral and inspired millions to protest, said at the trial on Tuesday.
She added: "At the time, I had lost a lot of faith in God".
Minnesota is a rarity in explicitly permitting such "spark of life" testimony about a crime victim ahead of a verdict.
The store clerk, who called police over a questionable $20 bill Floyd had used to pay for cigarettes, was emotional during his testimony Wednesday and told jurors he suspected Floyd was already dead by the time the ambulance arrived. Bravinder said the phrase cardiac arrest is used for patients that do not have a pulse and their heart has stopped. It laid out the events of others involved in detail, from the moment they arrived on scene to after Floyd is taken away, and how they talked to bystanders and eyewitnesses afterward.
Chauvin holds him by one hand and pushes his other hand against the police vehicle.
"We gotta control this guy 'cause he's a sizable guy... and it looks like he's probably on something".
