Real story behind the killing of Isnilon Hapilon and Omar Maute: drone or sniper?

Do you know how these two terrorists, Isnilon Hapilon and Omar Maute were killed?

Based on several stories shared by my Maranao contacts, four men wearing the traditional black Abayas called out on Isnilon Hapilon. They spoke in Tausug, the dialect of Hapilon. Hapilon thought that these men were the 'reinforcements" he asked from his fellow Tausugs from Basilan and Jolo, Hapilon went down from the building where he was hiding. Omar Maute followed him.

When Hapilon came out of the building, he was spotted immediately by a sniper. Hapilon tried to duck but it was too late. He was hit. It was too late also for Omar. He was hit in the chest.

Afterwards, a swarm of Filipino special forces swooped down on the building, secured the bodies of the two ISIS terrorists and managed to get the hostages away from other jihadists.

The bullet which hit Hapilon and Maute came from a 50-caliber sniper's rifle. Sources told me the sniper was not far from where Hapilon and Maute were. Two sources however, told me it was a drone that really killed the two jihadists. The drone had sophisticated night spotting capabilities. It was also armed with a 50-caliber automatic gun. 

When another leader, Dr. Ahmad learned of the deaths of the two, he and his security detail tried to escape from where they were hiding by fighting their way out. A hole which led to another location sealed their fate. Waiting at the other side were a team of special forces, some of them of Malaysian origins.
