ALBUQUERQUE, N.M. (AP) — Five extended family members who had been living on a remote New Mexico compound where authorities say a 3-year-old boy died before it was raided last year have been indicted on terrorism-related charges that accuse them of conspiring to attack U.S. law enforcement officers, military members and government employees, authorities said Thursday.

The superseding indictment against the suspects, who have been in federal custody since August on firearms charges, came six months after authorities first descended on their squalid compound near Amalia, just south of the Colorado state line. A search for a missing Georgia boy — the son of suspect Siraj Ibn Wahhaj — had led law enforcement to the site on the high-desert where they found the child’s remains as well as 11 hungry children living in filth.

Authorities also have accused Wahhaj and others of transporting weapons across state lines to New Mexico, and training children at a firing range on the property to carry out school shootings and other attacks that never occurred.
