A、Because it is the local custom. B、Because another local couple claimed Baby 81. C、Because other parents were looking for child

A judge in the eastern town of Kalmunai says DNA tests have shown that a local couple are the biological parents of the boy known as Baby 81.
    The couple have always insisted the baby was their son and the family had been separated when towering waves smashed into their poor fishing village in December. Their neighbor later rescued Baby 81 from under a heap of garbage.
    But local child protection officials asked the Kalmunai court to order DNA tests before the baby was released from hospital. The officials argued that hundreds of parents were still searching for children missing after the tsunami destroyed Sri Lanka, leaving more than 1,000 children orphaned.
    The boy was even placed under police guard after his crazy parents tried to seize him from the medical facility. It’ s unclear when the baby will be handed over to the couple. But the judge has asked the parents to attend court later this week. The boy was called Baby 81 because he was the 81st patient admitted to Kalmunai hospital on the 26th of December.  More than 30,000 Sri Lankans died when the tsunami swamped two thirds of the island’s coast.
