Jury selection begins Monday for the first of six Baltimore police officers charged in the death of Freddie Gray.
Officer William Porter is charged with assault, manslaughter, misconduct in office and reckless endangerment.
He has pleaded not guilty.
Gray suffered a fatal spinal cord injury while in police custody. He died a week later, sparking riots and protests.
Protestors rallied in downtown Baltimore this past weekend to call attention to the death of unarmed black men at the hands of police around the country.
