The newspaper carrier found the child a short time later, and he wrapped the baby in a blanket before calling 911.
Just before 4:30 a.m, the Fresno Bee reports one of its own newspaper carriers, Aurelio Fuentes Jr., spotted the baby lying in the dark on Avenue 13 1/2 near Road 35.
In the middle of the road sat a squirming bundle; the 21-year-old could hear the screams over his auto radio, turned low as he delivered newspapers in Madera Ranchos, Calif., early Monday, per the Fresno Bee.
Initially, he thought it was some kind of animal before realising it was a baby girl.
"It could've been worse because out it's pitch black - there could've been coyotes, there are cars going by fast down that road", Fuentes added.
The Madera County Sheriff's Office said they are searching for the mother, who is accused of leaving the baby on the side of the road. "This female got out of her auto, asked the man if he could help her and asked him to take her child", the police spokesperson said.
The unidentified man told the mother to take her child to the fire station or a nearby children's hospital - but the women just drove away. This female got out of her vehicle, asked the man if he could help her and asked him to take her child.
The baby was taken to the nearest hospital and is expected to make a full recovery. Witnesses say she is possibly a young Hispanic woman in her early 20s.
The child will be placed in the care of child protective services when she is fully recovered.
The CHP said it wanted to remind the public of California's Safely Surrendered Baby Law.
Pogue said the situation was inexplicable and also noted that any newborn infants can be safely surrendered at any designated "safe surrender site" - a fire station or hospital - without any questions asked or the mother facing any charges.
