"SALT LAKE CITY -- Federal authorities in charge of the nation's biggest bust of artifact looting and grave-robbing are targeting more suspects ranging from those who do the digging to wealthy buyers in the lucrative black market of ancient Southwest relics.

Twenty-five people have already been charged after a long-running sting operation involving a bounty of artifacts taken from federal and tribal lands in the Four Corners region.

More arrests are likely, according to federal officials. Among the next targets could be wealthy collectors who fuel the underground trade."
