What is Officer Nero's case about?
Nero is not charged in Gray's death, but is accused of putting him into a dangerous situation. He is charged with second-degree assault and misconduct related to Gray's arrest, and reckless endangerment and a second count of misconduct stemming from the way Gray was loaded into the van.
The trial also involves allegations that Nero failed to care for Gray when he did not secure him with a seat belt in the back of the arrest van, where Gray ultimately suffered a fatal spine injury.
Gray had run from the officers in what they have described as a high-crime area. Gray, 25, suffered severe spinal cord injuries while in the back of the van, prosecutors say, and died a week later.
