The Philippine Daily Inquirer reported on August 20, 2008 that about 25 students in a public high school in Calapan City, Mindoro province have suffered seizures and shortness of breath due to what the principal of the school has attributed to being “possessed by evil spirits.” …A mass was offered by a Catholic priest at the request of frightened students, and local shamans have sacrificed two black pigs to appease the angered spirits.
