The Lucas County Coroner says the baby found in a freezer inside an East Toledo home was boy and born alive.
The autopsy revealed the infant was full term. The child's identity will be determined once DNA analysis is complete.
Toledo police are now treating the case as a homicide.
20-year-old Kenisha Pruitt and 18-year-old Antonio Cervantes were arrested on Saturday and charged with endangering children.
The couple's former landlord found the baby while cleaning out the home.
They are behind bars in the Lucas County Jail on $1 million bond each.,
