A psychiatrist says Chai Soua Vang had a history of suicidal and homicidal thoughts dating back two decades or more. Psychiatrist Robert Rawski examined Vang before the St. Paul man went on trial for the fatal shootings of six Wisconsin deer hunters. In the report -- obtained by the Milwaukee Journal Sentinel -- Rawski also says Vang believed the voice of an "evil shaman'' has spoken to him occasionally since 1995.
