Dr. Martin Tobin, a pulmonary expert, testified that there was “absolutely no way” that Floyd’s chest could expand properly to breathe.
During his testimony, Tobin had been shown a series of still images from body worn camera footage from the scene that he previously reviewed. At one point, Tobin noted the significance of an image where you see Floyd reaching out with his knuckles pressed against the tires of the squad car while Chauvin is on top of him.
Tobin said, “To most people, this doesn’t look terribly significant. But to a physiologist, this is extraordinarily significant.”
“This tells you that he has used up his resources and he’s now literally trying to breathe with his fingers and knuckles,” he added.
