The Latest on the murder trial for a Baltimore officer facing charges stemming from the death of a 25-year-old black man who died after suffering a critical injury in police custody (all times local):

9:30 a.m.

A handful of demonstrators and many photographers and videographers are gathered outside a Baltimore courthouse to await a verdict in the trial of one of the six Baltimore police officers charged in the arrest and death of a young, black man.

A judge is expected to announce his decision Thursday on the charges Caesar Goodson faces, including murder. Goodson is charged in the death last year of Freddie Gray, who was a passenger in Goodson's detainee transport van.

Officer William Porter's case ended in a mistrial, while Officer Edward Nero was acquitted. Porter and three other officers have trials scheduled this summer and fall.

Nero arrived at the courthouse Thursday amid security from sheriff's deputies, who went inside with him.

Demonstrators' signs read, "Justice for Freddie Gray," ''Jail Killer Police" and "Stop the War on Black America."

A Baltimore judge is poised to deliver his verdict in the murder trial of an officer who drove the police van where a black arrestee's neck was broken, triggering some of the worst riots the city has ever seen.

Caesar Goodson was charged with murder, manslaughter, assault, reckless endangerment and misconduct in office.

Twenty-five-year-old Freddie Gray died a week after suffering a spinal injury in Goodson's wagon, where officers left him handcuffed and shackled but unrestrained by a seat belt. His death set off protests and violence, and prompted State's Attorney Marilyn Mosby to bring charges against six officers.

The sweeping case ended the career of the police commissioner and aborted the political future of the mayor. Some say Mosby's reputation also hinges on its outcome.
