"We both suffered from chronic pain: mine was in my neck, his was in his back".
The other three former police officers involved in the arrest-Tou Thao, Thomas Lane, and J. Alexander Kueng-are to be tried separately later this year.
The trial of Derek Chauvin, who is charged with killing George Floyd, is set to resume in Minneapolis on Thursday. Chauvin's defense team says that Floyd's physical condition, specifically problems with his heart, contributed to his death.
Fentanyl and methamphetamine was found in Mr Floyd's system during an autopsy.
Ross' testimony could help prosecutors blunt the argument that drugs killed Floyd.
In this image from video, Hennepin County Judge Peter Cahill presides, Wednesday, March 31, 2021, in the trial of former Minneapolis police Officer Derek Chauvin, in the May 25, 2020, death of George Floyd, at the Hennepin County Courthouse in Minneapolis, Minn. The footage sparked global protests against police brutality.
Mr Chauvin, a 19-year veteran of the police force, faces up to 40 years in prison if convicted of the most serious charge - second-degree murder.
In her evidence, Ms Ross described how both she and Mr Floyd struggled with their addiction to painkillers throughout their relationship.
Courteney Ross, who was dating George Floyd for almost three years before his death in May, delivered tearful testimony Thursday about their shared struggle with an 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".
In March 2020, Ross drove Floyd to the emergency room because he was in extreme stomach pain, and she later learned he overdosed.
In the months that followed, Ross said, she and Floyd spent a lot of time together during the coronavirus shutdown, and Floyd was clean.
She told jurors she believed Mr Floyd was not taking any drugs from the time he was discharged from hospital up until two weeks before his death, when she noticed "changes in his behaviour".
As McMillian cried, Chauvin and his defense attorney, Eric Nelson, could be seen writing down notes.
The witness said she had gone to the shelter because her sons' father was staying there. Ross said that they had purchased drugs from Hall in the past.
One of the newly-released videos is from Chauvin's body camera and there is audio of an exchange between him and a bystander immediately after Floyd is put in an ambulance and taken away from the scene.
Beleaguered Syria suffers also due to Suez Canal closure
Egypt's Leth Agencies tweeted the ship had been partially refloated, pending official confirmation from the Suez Canal Authority. According to data from Lloyd's List, the blockage is holding up an estimated $9.6 billion of goods each day - or $400m an hour.
"They were still on top of him", Bravinder told the jury.
Also testifying on Wednesday was Charles McMillian, 61, who said he was driving by that day and stopped to see what was going on because he is "just nosy".
Another officer checked Mr Floyd's wrist for a pulse and said he could not find one.
Based on CCTV footage, Mr McMillian appears to have been the first bystander on the scene of Mr Floyd's arrest. "In my mind at least, we wanted to get away from that".
She told the court she had started filming on her phone because she "saw a man terrified, begging for his life". She said: "It's one of my favourite stories to tell".
She was waiting in the lobby to see the father of her son, exhausted after closing up the coffee shop where she worked. Floyd came over to check on her.
"Mr Floyd has this great Southern voice, raspy".
"I was exhausted. We've been through so much, my sons and I, and (for) this kind person just to come up and say, 'Can I pray with you?'.it was so sweet".
"I thought, I was exhausted", she continued.
She said she became upset because the father was not coming to the lobby to discuss their son's birthday.
She added: "At the time, I had lost a lot of faith in God".
Matthew Frank, a prosecutor, then asked her if she even it her identification with her.
On Wednesday, four police body camera videos and various surveillance videos were played for the jurors.
Bystander and police bodycam video showed officers pulling Floyd from his SUV at gunpoint, then struggling to put him in the back of the squad vehicle as a panicky-sounding Floyd writhed and cried, "I'm claustrophobic!"
It was then that they put him on the ground.
