Defense attorneys have called a forensic pathologist as their first witness in the manslaughter trial of a Baltimore police officer charged in the death of Freddie Gray.

Dr. Vincent DiMaio took the stand Wednesday morning at the trial of Officer William Porter.

The pathologist says he disagrees with certain interpretations of the autopsy findings, including the timing of Gray's fatal injury.

Maryland Assistant Medical Examiner Dr. Carol Allan testified for the state that Gray's neck was most likely broken between the second and fourth stops of a ride in a police van. Gray was handcuffed and shackled, and unrestrained by a seat belt while in the van.

The defense contends the van driver, not Porter, was responsible for ensuring Gray's safety.
