"Ismael underestimated the power of the typhoon," Zarate says. "He died at 0600 hours, 30 minutes after he made a mercy call to my cellphone. I missed the call."
When the Red Cross couldn't help search for Fernandez, Zarate contacted Cawston as the New Zealand chapter was the nearest to the Philippines.
Funds were raised to send Zarate by bus to Tacloban, where he desperately searched refugee camps. Messages scrawled on scraps of paper such as paper plates were photographed and sent back to Cawston.
"I pored over refugee names for hours in the hopes of finding Ismael's name among them," Cawston says.
"Sadly, I didn't - but I did find the name of a New Zealander [Annabelle Kelly, see story at right]."
Cawston hardly left his computer for two weeks as he tracked the efforts. "The search for Ismael became all-consuming," he says.
Fernandez was recovered in a carpark full of bodies and identified by his tattoos.
The multinational effort refocused on fundraising to get Fernandez's body back to his family in LA.
"Photos of Ismael shook me up pretty badly," Cawston says.
The Los Angeles and London Angels then took over until Fernandez was buried on December20.
Cawston had previously been involved tracking a suicidal person in London and sending an ambulance to rescue the woman - all from his home in Auckland.
Almost 2000 people remain missing in the Philippines.
Mum rejoices in vital message
Andy "Chieftain" Cawston trawled through hundreds of photos of desperate messages etched on scraps of paper. "I looked until my eyeballs were almost bleeding."
Among them was a message to Auckland woman Annabelle Kelly, whose two sons disappeared during the typhoon. Last week she was relieved to get word that her sons has survived.
A message, translated by the Guardian Angels, reads: "Call John Paul Juntilla in Norway (brother) and Anabelle Kelly (mother) in New Zealand. I'm okay, Jo-ann Juntilla, but I have no contact with Jabar Juntilla until now."
A spokesperson for the Ministry of Foreign Affairs and Trade said no New Zealanders were killed in the typhoon.
