A man has been sentenced to 25 years to life for the murder of a 13-month-old baby girl, said the Sacramento County District Attorney's Office.

The incident occurred on July 11, 2014 when Washington's then girlfriend left the baby in his care and when the mother returned that afternoon she discovered the baby unresponsive and not breathing. The baby was then brought to UC Davis Medical Center where, shortly after her arrival, they pronounced her dead.

Doctors discovered bruising and multiple injuries to her head, body and other areas. A later autopsy showed she had suffered a "skull fracture with associated brain swelling, rib fractures and significant bruising on various parts of her body."

On Oct. 5, a jury convicted Guyland Washington for second degree murder and child assault which led to the 13-month-old's death.
