The "Zizian" group, which has roots in the San Francisco Bay Area, has been the focus of a multistate probe as investigators allege members are tied to a half-dozen killings in three states.

Three members of a group linked to six killings, including of a U.S. border patrol agent, were arrested in Western Maryland.

The leader of a cultlike group known as the Zizians that is linked to six killings in three states is due in a Maryland courtroom Tuesday along with two others.
