Freddie Gray, who's arrest was caught on video and sparked riots in Baltimore, died two years ago on Wednesday.
Gray was arrested on April 12, 2015 and died a week later from injuries he sustained while in police custody.
Baltimore City State's Attorney Marilyn Mosby charged six of the officers involved in Gray's arrest.
The trials of Lt. Brian Rice and Officers Edward Nero and Caesar Goodson resulted in acquittals. The state later dropped its cases against Officer Garrett Miller, Sgt. Alicia White and Officer William Porter.
