Love Has Won: Sheriff says cult used essential oils to hide rotting stench while worshipping mummified ‘Mother God’

Group members burned sage in ritual to honour decaying corpse of leader Amy Carlson

Graphic new details have emerged of how Love has Won worshipped the mummified corpse of cult leader Amy Carlson, known to followers as "Mother God".

In an exclusive interview with NBC’s Dateline, the sheriff who discovered the body spoke out after prosecutors dropped charges over the morbid ritual.

Saguache County Sheriff Dan Warwick tells Dateline’s Keith Morrison the group was burning sage in the room and covering Ms Carlson in essential oils to "keep the odour down" when he found her.

In a preview of the two-hour special airing Friday night, Mr Warwick said the group was effectively worshipping the mummified corpse.

"Wow, I mean, it’s just [you] shake and go wow. There’s not much more I can say. I’ve been doing this for 26 years. I used to say I’ve seen it all. I don’t say that anymore," he said.

Seven members of the spiritual cult were taken into custody after the decaying body of Ms Carlson, 45, was discovered in the group’s headquarters in Colorado in April.

They were charged with misdemeanour child abuse as two minors were inside the home, but the Saguache County District Attorney later dropped all charges.

Mr Warwick told Dateline they should have faced charges for abuse of a corpse after he searched the cult’s headquarters on 29 April and found Ms Carlson dead, mummified, and covered in Christmas lights with eyes decorated by glitter.

Investigators believed Ms Carlson died elsewhere and was transported to Colorado, possibly from California.

Deputies arrested "Father God" Juan Castillo, along with members Ryan Kramer, John Robertson, Karin Raymond, Christopher Royer, Sara Rudolph, and Ma obdulia Franco Gonzalez.

Saguache County Sheriffs Office’s “probable cause statement in support of warrantless arrest”, obtained by The Independent, said police were tipped off to Ms Carlson’s death by group member Miguel Lamboy, also known as "Archangel Michael Silver".

"Mr Lamboy stated that Ms Carlson’s skin appeared to be grey in colour and her eyes were glazed over or missing. Mr Lamboy stated that it was obvious that Ms Carlson was dead because her eyes were missing," the statement said.

"Mr Lamboy stated that the body appeared to be mummified with Ms Carlson’s teeth exposed through the lips. Mr Lamboy stated that Ms Carlson was wrapped in a cloth."

The Ascension of Mother God airs Friday at 9pm ET.
