Isnilon Totoni Hapilon (March 10, 1968 – October 16, 2017), also known by the nom de guerre Abu Abdullah al-Filipini, was a Moro Filipino Islamist militant affiliated with ISIS. He was formerly leader of Abu Sayyaf Group, before its battalions pledged their allegiance to Abu Bakr al-Baghdadi. An April 2016 issue of ISIL's weekly newsletter Al Naba said that Hapilon had been appointed as "emir of all Islamic State forces in the Philippines". In the early morning of October 16, 2017, he was killed by the Philippine Army in the Battle of Marawi, along with Omar Maute. Early life According to the Federal Bureau of Investigation and the United States Department of State Rewards for Justice Program, Isnilon Totoni Hapilon was born on March 18, 1966, in Lantawan, Basilan, Philippines. However, his school transcripts indicate his birthdate as March 10, 1968 and his birthplace as Maluso, Basilan. His listed parent/guardian is Haridja Hapilon, a housekeeper. According to the Philippine Daily Inquirer, he had five siblings, and his father was a village imam named Hapilon Totoni. Hapilon started elementary school in 1978, at the age of 10, enrolling at Maluso Central Elementary School. He had a perfect attendance from the first to the fifth grade, but had 28 days of absence and six days of tardiness in his sixth grade claiming that he had to "run errands"; he finished in 1984 with an average grade of 78%. He then enrolled at Basilan National High School, but his transcript ends with his first year even though he was eligible to proceed to second year. In an interview with the Philippine Daily Inquirer, former Lantawan mayor Tahira Ismael, Hapilon's madrasa classmate, claimed that Hapilon "performed poorly in academics". The FBI Most Wanted Terrorists list, and some newspapers including the Philippine Daily Inquirer, The Straits Times, and The Philippine Star, reported that Hapilon earned an engineering degree from the University of the Philippines. On May 31, 2017, the University of the Philippines issued a statement refuting the earlier reports, declaring that they have no record of an alumnus or former student named Isnilon Hapilon.
