I have been doing some further 'investigation', trying to pinpoint the problem of why the case seems to be going nowhere. (And to me, it has seemed that way for a couple of months.)
I have found the definitive article, the information that reveals to me the truth of it all. I understand now why it is being run as if it were a top secret operation.
Make no mistake, Mike Schrunk is running the entire investigation. Underhill and Frink are just [yes men], hoping that Schrunk will retire before they do so that they might get to run for District Attorney. Based on this article, I doubt their dreams will be realized.
Schrunk appears to wield alot of power. Alot! Power over judges; over his assistant DAs, of course; over the police; the sheriffs; as nearly as I can tell he is probably the single most powerful person in all of Multnomah County.
So... if I was in charge, he would be forced to retire. The DAs office would get out of the investigation business, and some real detectives would be brought in to try to pick up the pieces and solve this case. And, much of the secrecy would have to go.
Here is the article:
