Transcripts of the body camera footage, from two of the four police officers charged in the killing of Mr. Floyd, were released last week as part of a motion on behalf of one of the junior officers, Mr. Lane, to have the case against him dismissed.
Mr. Lane, 37, was a rookie officer, and one of the first officers on the scene. His lawyer, Earl Gray, has sought to shift the blame to Mr. Chauvin, a senior officer who trained new recruits to the force, arguing that Mr. Lane was following the lead of Mr. Chauvin.
According to the transcripts and an interview Mr. Lane gave to investigators, Mr. Lane suspected that Mr. Floyd was having a medical emergency and asked Mr. Chauvin if they should turn Mr. Floyd on his side as he was facedown and gasping for breath. Mr. Lane also rode along in the ambulance to the hospital with Mr. Floyd, administering chest compressions in an attempt to revive him.
Mr. Chauvin, a 19-year veteran of the Minneapolis Police Department, faces the most severe criminal charges, and three other officers are charged with aiding and abetting second-degree murder. All four were fired shortly after Mr. Floyd’s death. Their trial is scheduled to begin March 8.
Once an ambulance arrived — late, because paramedics had first gone to the wrong location — Mr. Lane went inside and administered chest compressions on Mr. Floyd, whose face appeared bloodied.
But even in the ambulance, at first, there appeared to be little sense of urgency, according to the newly seen footage, with minutes passing before anyone tended to Mr. Floyd.
