ST. PAUL  — Jurors weighing the fate of a Minnesota police officer who killed a black motorist last July ended their fourth day of deliberations Thursday without a verdict.

Deliberations were to resume Friday in the manslaughter trial of Officer Jeronimo Yanez. He shot Philando Castile during a traffic stop in a St. Paul suburb after Castile informed the officer he was carrying a gun.

Thursday’s deliberations passed quietly, with no sudden hearings or requests from the jury to review evidence. On Wednesday, the apparently deadlocked jury was summoned to court by the judge and told to keep deliberating.
