Some oddities:
--Police finally did a door-to-door canvas of the neighborhood to see if anybody had seen anything--FOUR YEARS LATER
--The FBI sent its agents on a wild goose chase across the country, trying to track down every Makarov replacement barrel ever sold, as though thekiller would conveniently keep the evidence and hand it over on demand.
--The US Attorney in Seattle, John McKay, according to his own version, was fired by the Bush administration because he was trying too hard to solvethe case.
When the government fires the prosecutor for trying too hard to solve the crime, there can only be one reason: THE GOVERNMENT DOES NOT WANT THISCRIME TO BE SOLVED.
