After George Floyd was killed by former Minneapolis police officer Derek Chauvin in 2020, Maryland's former Chief Medical Examiner Dr. David Fowler was called in as a defense witness for the 2021 trial.
On the stand, Fowler testified that, based on his study of the forensic evidence, Floyd's death should be classified as "undetermined" and not a homicide, due to a medley of factors including heart disease, drug use and carbon monoxide exposure.
