How did the investigation work?

The FBI and the BLM, concerned about looting on public and American Indian lands, developed a relationship with a major dealer in archaeological artifacts. For months, this dealer --identified only as the "Source" -- bought and sold artifacts from the Four Corners area while wearing a recording device. The undercover investigation was dubbed Cerberus Action, after the multi-headed dog of mythology who guards the realm of the dead.

What kinds of artifacts were swiped?

The 256 relics include ceramic figurines, a mug, bowls, seed jars, a clovis point, stone pipes, stone metate, ancient sandals, a hafted ax, a gourd necklace, a shell necklace, beads, an effigy bird pendant, a copper bracelet, a turkey feather blanket, knives and polishing stones.

How valuable are they?

The dealer bought them for $335,685. But scientists and law-enforcement officials say they are priceless cultural treasures.

Were any of the artifacts damaged?

Experts say the mere act of improperly excavating an archaeological site leads to the loss of significant historical information. Authorities have promised to take proper care of the recovered relics.

What's next?

Prosecutors have asked that all but one of the 24 defendants be released pending trial. A hearing on a request that Aubry Patterson be detained is scheduled for this morning. The defendants

have been ordered to make reasonable efforts to protect artifacts in their possession from damage until their cases are resolved.
