(CNN) The FBI has arrested the five adults who were living at a New Mexico compound where a boy was found dead, accusing them of breaking firearms and conspiracy laws, authorities said Friday.

Jany Leveille, 35, is accused of being in the United States illegally and is alleged to have had firearms and ammunition, a statement from the US Attorney and FBI said.

Four other people -- Siraj Ibn Wahhaj, 40; Hujrah Wahhaj, 37; Subhannah Wahhaj, 35; and Lucas Morton, 40 -- have been charged with aiding and abetting Leveille, and with conspiring with her.

A criminal complaint says FBI agents seized at least 11 firearms -- pistols, revolvers, a shotgun and rifles -- and a large quantity of ammunition at the compound in Amalia. The document alleges the firearms were transported to New Mexico from another state in Leveille's vehicle.

The complaint said Leveille came to the United States from Haiti on a six-month, nonimmigrant visa in 1998. She received no more visas, the complaint says.
