Mexican authorities have confirmed that members of a tiny, mysterious evangelical sect had "adopted" about a dozen children who vanished from a Mexico City children's shelter in 2008.

Prosecutors announced Tuesday that three more of the children had been found, bringing to 12 the number of kids located out of a total of 15 who went missing from the "Casitas del Sur" shelter.

A federal official says the three newly found people showed up last week at prosecutors' offices in Puebla state, not far from Mexico City. The official was not authorized to be quoted by name.

The Attorney General's Office said members of the religious group that ran the shelter had given the children to members of the congregation in a sort of illegal adoption.
