A baby is kidnapped from a couple’s home. The parents of the kidnapped child have blood types A and B. The police identify two suspects with a baby that matches the age and gender of the missing child.

From their driver’s licenses the police also learn that the suspect’s blood types are A and AB. Can the suspects be the biological parents of the baby, and if not, could this be the kidnapped child? Explain your answers.
