Ramón Gustavo Castillo Gaete, who refers to himself as “Antares from the Light,” is on the run from police after four members of his group were arrested by Chilean authorities for the ritualistic murder of an infant girl.

Chilean authorities arrested the four, including the child’s mother Natalia Guerra, on Thursday, though the killing played out last November (prior to what Gaeta reportedly believed would be the end of the world, said the BBC). Miguel Ampuero, the vice-chief of the Policía de Investigaciones de Chile, told reporters from the AP, “The baby was naked. They strapped tape around her mouth to keep her from screaming. Then they placed her on a board. After calling on the spirits they threw her on the bonfire alive.”

Investigators believe the cult was founded in 2005 and has only 12 members, reported the International Business-Times. Gaete is said to use the plant ayahuasca, a known hallucinogen more famously used in religious rituals by indigenous peoples (and now tourists) in what is now Peru, and was last scene traveling there to procure more of the plant.

Gaete is on Chile’s Most Wanted list.
