A newborn baby girl was discovered buried alive in a Los Angeles riverbed on Saturday by two women out for a walk. CBS News reports that the two women, Evangelina McCrary and her sister Angelica Blount, heard a strange crying noise when walking near a riverbed, in Compton, Calif., south of Los Angeles. At first, the sisters thought the cries were coming from a cat, before realizing they were the cries of an infant.

Local police received reports of a crying baby near the riverbed, located near 136th Street and Slater Avenue, around 4 p.m. Police heard the infant cry upon their arrival, and located the baby buried alive under pieces of asphalt and rubble along a bike path. The infant appeared to be less than two days old.

Police rescued the baby from under the asphalt, and found her wrapped in a hospital-issued blanket. The baby’s vital signs were checked before police ultimately called paramedics to treat the infant at a local hospital. The baby is currently in stable condition, and is under hospital supervision.

Deputies are in the process of identifying the baby, urging the public Saturday to come forward with any information that may help assist in the process. Those with information regarding the baby are being directed to the Special Victims Bureau.

California participates in a program called “Safe Surrender,” which allows a newborn child to be dropped off at a hospital or fire station, with no questions asked.
