During a four-hour morning work session, jurors at the "Baby Kate" trial were not able to reach a verdict.

Around noon Friday, Oct. 14, jurors left the Mason County courthouse and were escorted by court staff to a downtown restaurant for a lunch break.

The court said deliberations would continue after they returned.

Friday morning, jurors could be seen gathering briefly around a table inside the closed courtroom. Several exhibits used during the trial were placed on the table. Members of the jury were reviewing those items, including Kate's car seat and diaper bag.
