Derek Chauvin trial to resume as MMA fighter who witnessed ‘blood choke’ during George Floyd arrest returns

The trial for the ex-Minneapolis police officer Derek Chauvin charged in George Floyd’s death is to resume Tuesday with testimony from an MMA fighter who witnessed Floyd’s arrest as he laid face down on the pavement with Chauvin’s knee pressed to his neck.

Williams will continue his testimony -- which could provide crucial insight into the potential cause of death -- as both sides argue whether Floyd was killed by the officer through mechanical asphyxia or due to a heart arrhythmia exacerbated by methamphetamine and fentanyl in his system prior to the arrest. As he first testified Monday, Williams described various chokeholds and how they are used. He described Chauvin's position with his knee on Floyd's neck as a "blood choke." As he arrived outside the store, Williams said he noticed two police vehicles and a commotion.
