Jan 23 - A comprehensive case review into the 2005 death of author-journalist Hunter S. Thompson, including autopsy records, has affirmed authorities' original conclusion that he took his own life, the Colorado Bureau of Investigation said on Friday.

The review, conducted after the writer's widow, Anita Thompson, raised questions about the official suicide ruling, found no "new physical evidence, facts, or circumstances to support a conclusion different from the 2005 investigation," the CBI said.
