TAOS, N.M. (Reuters) - A 3-year-old boy whose remains were found buried at a New Mexico desert compound died during a ritual to “cast out demonic spirits,” other children living there told investigators, a prosecutor said in court on Monday.

Authorities found the remains at a ramshackle compound north of Taos where 11 other children were found alive but malnourished in a raid on the site 10 days ago.

The prosecutor said during a court hearing for five adults arrested on charges of abusing the 11 children that they had been trained to use weapons and defend the compound in the event of an FBI raid. The hearing was to ask the judge to deny bail to the suspects.
