Baltimore Police Officer William Porter is set to face a jury in the first trial stemming from the death of Freddie Gray.

Court spokeswoman Terri Charles says the 12 jurors will be seated Wednesday in Baltimore Circuit Court. She says opening statements also could be heard Wednesday.

The prospective jurors are from a pool of 150 questioned Monday and Tuesday by Judge Barry Williams, mostly out of public view.

Porter has pleaded not guilty to charges of manslaughter, second-degree assault, misconduct and reckless endangerment. He's among six officers charged in the case.

Gray was a 25-year-old black man who died in April from injuries he suffered in police custody. His death triggered protests and rioting, and helped fuel the Black Lives Matter movement.

Porter is also black.
