George Floyd said more than 20 times that he couldnt breathe, but his pleas were repeatedly ignored as a white police officer knelt on his neck, killing him, according to transcripts of body camera footage released Wednesday.

The accounts add shocking new details of the minutes surrounding the Black mans death in Minneapolis on May 25 and show how a cooperative encounter with officers quickly turned deadly, setting off nationwide protests calling for the dramatic reform of American policing.

In the transcripts, Derek Chauvin , a former Minneapolis police officer who has been charged in Floyds death , repeatedly ignores the handcuffed mans calls for air and disregarded another officer who asked if Floyd, who was pinned to the pavement, should be moved onto his side.

Floyd: My stomach hurts. My neck hurts. Everything hurts. I needs some water or something, please. Please? I cant breathe, officer.

Chauvin: Then stop talking, stop yelling.

Floyd: Youre going to kill me, man.

Chauvin: Then stop talking, stop yelling, it takes a heck of a lot of oxygen to talk.

The transcripts came from body cameras worn by two of the four officers who were involved in the arrest of Floyd and have since been fired, Thomas Lane and J. Alexander Kueng. An attorney for Lane asked that his case be dismissed on Wednesday, pointing out that the transcripts show Lane asked Chauvin twice if he should turn Floyd on his side.

Chauvin, a 19-year veteran of the department, refused. No, hes staying put where we got him, Chauvin said.

Chavin has been charged with second-degree murder and second-degree manslaughter and faces up to 40 years in prison if convicted. Lane, Kueng and Tou Thao, the fourth officer, have been charged with aiding and abetting the killing of Floyd.
