He testified on behalf of George Floyd's killer. Now his decisions as Maryland medical examiner are being reviewed.

From her home in Baltimore last year, Tawanda Jones watched police officer Derek Chauvin stand trial in a Minneapolis courtroom for the murder of George Floyd. While the content of the widely televised proceedings in 2021 was disturbing, for Jones the most troubling part was the testimony of expert pathologist Dr. David Fowler. 

Appearing on behalf of the officer accused in Floyd's death — documented in the infamous video showing Chauvin's knee on Floyd's neck — Fowler testified that the cause of death could not be determined: "This is one of those cases where you have so many conflicting manners," Fowler said. "So I would fall back to undetermined."

Fowler testified it was impossible to say what killed Floyd.
