Attorneys for six Baltimore police officers charged in the death of Freddie Gray are asking a judge to move their case out of Baltimore, arguing it will be impossible to select an impartial jury and receive a fair trial.

The officers face charges ranging from assault to second-degree “depraved-heart” murder.

Gray’s death April 19 prompted a wave of protests that on two occasions gave way to violence, looting and arson. The U.S. Justice Department announced it’s conducting an investigation of the city police department.

In a lengthy motion filed Wednesday, the defense attorneys argue that, among other reasons, because every Baltimorean was under an emergency curfew to control the unrest, “an insurmountable prejudice” exists.
