Nine-year-old Elysia Laub was playing in her Indiana backyard Monday when she saw something moving.
"I looked over and saw these legs kicking and I thought, 'Is that a pig?'" Because we have two pigs and I thought maybe they had a baby or something," Elysia toldWGN9 News.
She immediately ran back to the house to tell her mom.
Her mom, Heidi, went outside to find a newborn baby girl with her umbilical cord still attached, sunburnt and laying wrapped in a black sheet.
"I scooped the whole thing up, ran to the house with her, wrapped her in a new blanket, and that's when I realized that placenta was still attached," Heidi told the outlet.
While Heidi took care of the baby, she told her daughter to run inside and call 911.
Temperatures climbed close to 90 degrees in Indiana on Monday, and the Sheriff's Office estimates that the newborn was outside for at least several hours — and possibly overnight.
The baby was taken to the nearby hospital, where she was treated for sunburns, but is being described as a "healthy young girl," according toNBC Chicago.
Police are calling the infant "Miracle Jane Doe," the outlet reports. And during a press conference, Lake County Sheriff John Buncich said of Elysia: "Had she not gone into the backyard to play, tragic results could have occurred. She's a guardian angel for this child."
Investigators are searching for the newborn's mother and ask anyone with information to the Lake County Sheriff's Office at 1-800-750-2746.
