The Hennepin County Medical Center doctor who treated Floyd and declared him dead last May testified that he believed Floyd likely died of asphyxia. Dr. Bradford Langenfeld, an emergency medicine physician, said he treated Floyd for about 30 minutes on May 25, 2020, as hospital staff unsuccessfully tried to restart his heart. Based on what paramedics reported and on Floyd's medical condition, Langenfeld said the "more likely possibility" of Floyd's cardiac arrest was hypoxia, or lack of oxygen. "Doctor, is there another name for death by oxygen deficiency?" prosecuting attorney Jerry Blackwell asked. "Asphyxia is a commonly understood term," Langenfeld responded. On cross-examination, Langenfeld said that hypoxia can be caused by many things, including drugs such as fentanyl, methamphetamine or a combination of both. Earlier Monday, Judge Peter Cahill spoke to jurors outside of the view of cameras about an allegation of juror misconduct. He ruled there was not been any misconduct and the jurors were credible. #ChauvinTrial #CNN #News
