"The Minneapolis doctor who declared George Floyd dead testified today that it's more likely Floyd died of oxygen deprivation than a heart attack or drug overdose.
The big picture: Dr. Bradford Langenfeld and Chief Medaria Arradondo's testimonies push back against key aspects of the defense's case.
Langenfeld testified that Floyd didn’t show specific symptoms that would be common after a heart attack or signs of drug toxins in his system, Axios' Shawna Chen reports.
Arradondo testified that Chauvin kneeling on Floyd's neck was "not de-escalation."
Arradondo said he has formed the opinion that Chauvin was using a conscious neck restraint.
Nelson asked if using a knee on someone's neck to restrain them is against MPD policy.....
Arradondo clarified, "It is contrary to our training to indefinitely place your knee on a proned, handcuffed individual for an indefinite period of time."
