The kidnapper of the baby renamed Eric leaves her own already-dead baby Eric in the desert with the kidnapped baby's hospital bracelet to make his mother believe he died after being kidnapped so they would stop looking or him. However, it turns out the kidnapper's original dead baby has both a birth and death certificate after living only one day in the hospital. No hospital would simply give a new mother of a dead baby the body to dispose of, and if she had stolen it there would have been an investigation to coincide with the kidnapping, which would have led to an immediate conclusion. Finding the birth and death certifications helped Rose close the case, but introduced implausible circumstances.
