BALTIMORE — A police officer charged in the Freddie Gray case chose Tuesday to stand trial before a judge rather than a jury, eliminating a potential wild card in the divisive and emotionally charged case.

Officer Edward Nero was one of three officers who arrested Gray when he made eye contact with one of them and took off running in a high-crime area in April 2015. The officers took Gray, a 25-year-old black man, into custody and he was placed in the back of a police van, where he was critically injured during a 45-minute trip to a nearby police station.

He died a week later, sparking protests and fueling the Black Lives Matter movement, becoming a rallying cry in the growing national conversation about the treatment of black men by police. On the day of his funeral, rioting and looting broke out and a city-wide curfew was imposed as the National Guard rolled in to help restore order.

Nero, one of six officers charged, faces assault, reckless endangerment and misconduct in office charges. His trial is scheduled to begin Thursday and is expected to last about five days. The trial is seen as a bellwether case for the other two arresting officers who face the same charges. They have all pleaded not guilty.

Nero is the second officer to stand trial. Late last year, a jury couldn't reach a unanimous decision in the case against Officer William Porter, who checked on Gray several times after he was put in the police van.

While selecting the jury pool for Porter's trial, all potential jurors acknowledged that they were aware of the case and the $6.4 million settlement the city paid to Gray's family.

Nero's decision means that means Circuit Judge Barry Williams will hear the case. The trial will likely focus more on technical legal arguments than Porter's trial.

The trials for the officers have been on hold for about five months while attorneys argued about whether the officers should be forced to testify at one another's trials. Maryland's highest court ruled they did, and one of the officers is expected to take the stand in Nero's trial.
