The killing took place on Wednesday in a village near the Amazon city of Iquitos during a shamanic ceremony for tourists that included drinking the hallucinogenic tea that is embraced by advocates as a spirit cure.
The supposed teachings of plants like ayahuasca, datura and tobacco attract travelers from all over the world. Some try to heal diseases, others try to find answers. In the past couple of years, dozens of retreats have been built near Iquitos to accommodate these practices.
