A Los Angeles County sheriff's deputy who dug a newborn girl out of a hole where she was buried alive says he believes the infant had "a touch of God that day" to survive.

Deputy Adam Collette described for reporters Monday how he kneeled on asphalt near a bike path last week and heard the muffled cries of the child.

Collette, a father of two young daughters, says he knew from the sound that the baby was hungry and cold.

The deputy says that when he removed asphalt and rubble covering the child and held her, he could see the relief in her face.

Doctors say the baby might have died within hours, but she's now stable and healthy at a hospital. Officials are asking the unknown mother to come forward.
