Officer William G. Porter, who joined the force in 2012, was charged with involuntary manslaughter, second-degree assault and misconduct in office. Porter, 25, responded when Officer Caesar R. Goodson Jr., who was driving the police van, asked for additional units to check on Gray. The prisoner told Porter he could not breathe. Porter asked Gray if he needed a medic. Gray said "yes" twice. The officer helped lift Gray to a bench but did not assess his condition or call for medical assistance. Porter also was present later when Goodson picked up another prisoner, and White and others discovered that Gray was unresponsive.
