Expert disagrees with 'homicide' conclusion in Gray's death
... Asked about the Maryland medical examiner's conclusion that Freddie Gray's death from injuries sustained in police custody was a homicide, Dr. Vincent DiMaio, one of the nation's leading forensic pathologists, said: "I'd have to respectfully disagree, and I know a number of other medical examiners do. It would be more appropriate to have classified this case as either an accident or 'undetermined,' because the way it's being called a homicide is, in a way, something that a jury has to decide. A medical examiner is not a lawyer, is not a jury. … They're saying [Gray's death] was not an unforeseen event. That's something for a jury to decide, not the doctor to decide."
