For 17 years, Gracia and Martin served with New Tribes Mission in the Philippines where Martin was a jungle pilot delivering mail, supplies, and encouragement to other missionaries, and transporting sick and injured patients to medical facilities. Gracia served in various roles supporting the aviation program and also home-schooling their children – all of whom were born in the Philippines.
On May 27, 2001, while celebrating their 18th wedding anniversary at Dos Palmas Resort off Palawan Island, the Burnhams were taken captive by a militant group of Muslims called the Abu Sayyaf Group.
For more than a year, and under the total control of their captors, they were constantly on the move living in primitive conditions in the jungle, evading capture from the Philippine military, enduring gun battles, and witnessing unspeakable atrocities committed by the men of Abu Sayyaf Group.
On the afternoon of June 7, 2002, over a year since their abduction, the Philippine military attempted another rescue. Tragically, Martin was killed during the gunfight. Wounded, but alive, Gracia was rescued and returned home under a national spotlight.
