Four Filipino hostages managed to escape in the first days after the seizure. But the Abu Sayyaf militants, led by spokesman Abu Sabaya, moved quickly to consolidate their captives and their leverage, retreating from Palawan to the island of Basilan. The group's tactics were fluid and brutal: they took new hostages during raids, released some for ransom, and killed others to make political statements. On June 12 -- Philippine Independence Day -- Abu Sabaya announced that he had beheaded Guillermo Sobero because security forces had refused to halt a rescue operation. Sobero's body was found months later in a shallow grave in Basilan. The militants conducted a raid on a coconut plantation called Golden Harvest, taking fifteen more people captive. Author Mark Bowden later described how they "used bolo knives to hack the heads off two men," noting that the number of hostages waxed and waned as some were ransomed, new ones taken, and others killed.

The crisis intensified in Lamitan, where the Abu Sayyaf fighters clashed with Philippine military forces in prolonged gun battles. Five Filipino captives escaped during the fighting, but the militants had already killed two hostages in the preceding days. On August 2, suspected Abu Sayyaf members raided the town of Balobo in Lamitan, seizing between 32 and 35 villagers. Three days later, the Philippine Army rescued thirteen hostages, including several children, after another firefight. The violence spread outward like ripples from a stone: more kidnappings, more clashes, more burned buildings -- including a chapel. Martin and Gracia Burnham remained in captivity throughout, enduring months of jungle marches, deprivation, and the constant presence of death. Their ordeal would eventually last over a year.

The Dos Palmas crisis drew the United States directly into Philippine counterterrorism operations. One thousand American troops deployed to the southern Philippines for six months, providing training and support to the Armed Forces of the Philippines in what became one of the earliest post-9/11 military engagements against Islamist militants in Southeast Asia. The rescue operation that finally ended the Burnhams' captivity on June 7, 2002, resulted in Martin Burnham's death and Gracia's survival, wounded but alive. She later testified at the trial of eight Abu Sayyaf members, identifying six of her captors. Fourteen Abu Sayyaf members were sentenced to life imprisonment in December 2007. One of those convicted, Alhamzer Limbong, was subsequently killed in a prison riot alongside two other Abu Sayyaf leaders.

The arrests did not end in 2007. Over the next decade and beyond, Philippine authorities and the National Bureau of Investigation tracked down perpetrators who had scattered across the archipelago. Some had assumed new identities: one worked as a construction worker in Taguig under the name Abu Kodano; another became a security guard in Manila's Port Area. Abu Sayyaf commander Sihata Muallom Asmad, who carried a 5.3-million-peso bounty, was killed in a firefight when police attempted to serve an arrest warrant in Sulu in 2014. Others were arrested in public markets, in apartment buildings, in places far from the jungles where they had once held people captive. The Dos Palmas kidnappings have been dramatized in a documentary series and two films, but the real story continued playing out in courtrooms and on the streets of Philippine cities for nearly two decades after that morning on Honda Bay.
