After four days of deliberation, the jury was unable to reach a verdict.

Nanny Kelli Jacobsen was accused of causing the death of one-year-old Ryder Morrison last June. Friday afternoon, the Benton County Superior Court judge ruled the case was a mistrial.

He was taken to Kadlec Regional Medical Center after Jacobsen called 911 and said he had fallen. He died about 13 hours after arriving at the hospital. Dr. Daniel Selove, the forensic pathologist who performed the autopsy on the Richland toddler, testified in court the child died from a subdural hematoma (a traumatic brain injury).

Benton County Prosecutors have not said if they will attempt to re-try the case.
