A woman who buried her newborn daughter alive in a Los Angeles suburb has been sentenced to 14 years in state prison.

Thirty-three-year-old Porche Washington was sentenced Wednesday after pleading no contest to attempted murder and causing great bodily injury to the infant.

Authorities say Washington hid her pregnancy from family and friends before giving birth last November. Days after she was released from the hospital, Washington placed the girl in a hole near a Compton riverbed and left her.

Two sisters walking on a nearby bike path heard the child's cries and called authorities, who found the infant wrapped in a hospital blanket under loose dirt and chunks of asphalt.

Los Angeles County has a "safe surrender" law allowing mothers to anonymously leave newborns at hospitals and fire stations.
