PORT-AU-PRINCE  - Four children from the same family have been found dead in Haiti after being treated by a witch doctor who claimed to be able to cure them of a mysterious illness, a local official said Friday. “Three girls and a boy, the eldest of whom was seven years old and the youngest only 15 months, suffered abuse from the healer who was treating them,” said Wilfrid Brisson, an official from the southern town of Marbial, told AFP. “They were then abandoned in their mother’s bed.” According to neighbors, the sorcerer - who was assisted by his brother - persuaded the victims’ mother that the children were possessed by a demon and said he could rid their soul of the devil.
