PORTLAND — Bringing a bizarre chapter in Oregon's history to a close, a disciple of the Indian guru Bhagwan Shree Rajneesh pleaded guilty to conspiring to kill the United States Attorney for Oregon, the U.S. Department of Justice announced Monday.

Catherine Jane Stubbs, known as Ma Shanti Bhadra, joins six other followers who earlier pleaded guilty to the attempted murder of Charles Turner.

Beginning in 1981, Rajneesh, a holy man from the Indian city of Pune, assembled a commune of some 7,000 adherents on a 100-square-mile ranch in Antelope.

The commune members plotted to take over the local county government in 1984, spiking local salad bars with salmonella in an effort to incapacitate non-Rajneeshee voters. The action sickened some 750 people and crippled the local economy.
