ST. PAUL, Minn. (AP) — The jury considering the fate of a Minnesota police officer charged in the death of a black motorist has wrapped up its third day of deliberations without a verdict.

Officer Jeronimo Yanez is charged with manslaughter in the July 6 death of Philando Castile. Yanez shot the 32-year-old cafeteria worker in a St. Paul suburb just seconds after Castile had informed him he was carrying a gun.

The jury appears to be having trouble reaching a verdict. Judge William Leary summoned the jurors to court Wednesday afternoon and re-read a portion of the jury instructions. He then sent them back to keep working.

The instructions dealt with their duty to work toward an agreement. Leary did not offer any explanation for why he read the passage.

Deliberations resume Thursday.
