Found this today - happened in August 2012:
http://www.dailymail.co.uk/news/article-2202459/Kyle-Joseph-Nolan-death-Peruvian-shaman-confesses-buried-body-U-S-teen-spiritual-retreat.html"Shaman Jose Pineda Vargas, 58, told the authorities that 18-year-old Kyle Joseph Nolan, from northern California, died on August 22 from exceeding the dosage of a medicinal brew called Ayahuasca while staying at the Shimbre Shamanic Center.
Nolan arrived at the shamanic center on August 17 and according to the Spanish-language site Peru21.pe, he paid $1,200 to take part in the Ayahuasca ritual.
The website for the Peruvian retreat, written in English, describes Pineda as ‘Master Shaman Mancoluto,’ and says he helps Ayahuasca initiates ‘open their minds to deeper realities, develop their senses and intuitive capabilities and unlock the person's untapped potential.’
The center says it holds five ceremonies held over 10 nights, when participants ingest psychedelic plants in ‘a comfortable private space in the middle of a virgin rainforest,’ but that people familiar with the side effects of the drugs are always on site to help.

Vargas was arrested following his confession, along with two other men who are accused of helping the shaman bury Nolan.
In 2011, Vargas was featured in a documentary called Stepping Into the Fire that tells the story of a wealthy New York Stock Exchange trader who travels to Peru - the land of his ancestors - in search of enlightenment, only to encounter the spiritual leader."

When you go to the site, there is also a photo of the shame-on and the retreat. From the photos, the place is a tourist trap, and the shame-on seems to be a PODIA.
Unfortunately for the victim, the pay-to-pray scheme turned out a pay-to-die one.
