3. Where it happened. While bystanders captured his arrest on video showing Gray moaning for help, the autopsy concluded that he suffered no injuries suggesting a neck hold or stemming from physical restraint.
4. When it happened. The medical examiner concluded that Gray's most significant injury was to the lower left part of his head. Given the descriptions of his demeanor and positioning in the van, it most likely occurred between the second and fourth stops made by the van driver, and possibly before the third stop, according to the autopsy.
5. Toxicology. Gray tested positive for opiates and cannabinoid when he was admitted to Maryland Shock Trauma Center, according to the autopsy. The report makes no further reference to the drugs found in his system.
