Authorities in Peru have arrested two people in connection with the murder of a B.C. man who was killed in a remote region of the country on Saturday (April 21).

Comox Valley resident Sebastian Woodroffe, 41, was reportedly in Peru as a researcher, investigating plant medicines and, specifically, the powerful hallucinogen ayahuasca.

He was lynched by a mob in eastern Peru and found buried in a shallow grave.

According to Peruvian media, the attack on Woodroffe was in retaliation for what was believed to be his role in the killing of Olivia Arvelo Lomas, a well-known shaman and civil rights activist. She was shot and killed near her home the morning of the same day that Woodroffe was killed.

According to CNN, Peruvian National Police are still investigating Lomas’ death. And, according to CBC News, their investigation is now focused not on Woodroffe but on a different suspect.

The CNN report states that the two men arrested for Woodroffe’s murder were identified with information gleaned from a YouTube video that appears to have captured his lynching.

Peru is a somewhat-popular travel destination for North Americans and Europeans interested in ayahuasca. Indigenous groups native to the Amazon basin have used the plant-based drug for centuries as a traditional spiritual medicine.
