Regarding the necklace and charms - in a recent UK Daily Mail article regarding the abuse by priests in PA, "Priests had children wear gold crosses to mark which of them had been abused"
Certain necklaces/charms probably denote a specific type or level of grooming. Judging by the amount of symbols on the pictured necklace I'm assuming that's a high level groomer (high priestess if you will) when you compare it to the simple gold cross necklace given to the young abused children.

The other thing anons should keep in mind, abuse is cyclical and generational, it is passed down. Everyone who has abused these kids have been victims themselves at some point - speaking as anon who's immediate family member suffered sexual and mental abuse by another immediate family member, but was thankfully strong enough to get the help needed to heal and break the cycle.
