Four members of an alleged assisted suicide ring were charged Wednesday with helping a 58-year-old Georgia man end his life.
Meanwhile, investigators in eight other states, including Montana, were looking into whether the group was involved in more deaths.
The FBI is also probing the Final Exit Network, an organization whose Web site said it is “dedicated to serving people who are suffering from an intolerable condition.” It wasn’t immediately clear how many deaths were being investigated.
On Wednesday, investigators raided the homes of the group’s volunteers in seven of the states, a group office in Georgia and a company in Montana that authorities said supplied items used in suicides, according to a news release from authorities in Arizona, where another death was being investigated.
