"We are like dog. We must smell," Syahrial says while sticking his head as far as he can into a pile of debris that towers above his 5'10" frame.
Syahrial, a volunteer with the Indonesian Red Cross' Evacuation team, is using his sense of smell to help find one of the approximately 100,000 bodies still reported missing from the tsunami which devastated Banda Aceh, Indonesia two months earlier.
Working seven days a week, the crews travel to where bodies wait to be found in pools of brown, toxic water and underneath the miles of rubble that stretch across the horizon.
Most of the victims still missing are thought to have been pulled into the ocean, lost forever.
"Maybe my sons," Syahrial says as he stretches one leg over a twisted piece of metal. "Maybe my sons."
