MESA, AZ - A newborn is struggling to survive at a Valley hospital after being found Sunday inside a shed with a fractured skull.
It happened at a home near Power Road and University Drive in Mesa, according to a Maricopa County Sheriff's Office spokesperson.
Currently the baby is in Child Protective Custody (CPS) and is in critical condition at a Valley Hospital. Sheriff's officials say the investigation will ultimately determine who takes custody of the baby.
Detectives say a 16-year-old gave birth in the shower on Sunday afternoon but didn't tell anyone.
When her parents realized what happened, they called 911.
When deputies arrived, it took 30 minutes to find the newborn.
ABC15 spoke with the teen's father, who says he didn't know his daughter was pregnant.
Mesa Fire Department Captain Forrest Smith says tragedies like this can be prevented.
Arizona's Safe Haven law allows newborns to be dropped off at hospitals, fire departments or police stations without any questions asked.
"We certainly want to see mothers take advantage of that if they find themselves in that situation. Again the way the law works is you have 72 hours to drop off your baby, 72 Hours is what dictates as being a newborn," says Smith.
Neighbors tell ABC15 the teenager goes to Red Mountain High School. Her name is not being released at this time
Sheriff Officials say it appears the pregnancy was carried to full-term.
Detectives say the teen could face charges but the investigation is still on-going.
