I get the impression this case is in the 'too hard' basket.
Instead of giving up why don't LE invite people like the Gary & Josh look at what they have.
What harm can it do after all these years?
Surely LE know these two guys know how to keep a confidence.

Remember the Green River Killer was interviewed several times prior to them arresting him because he was mad at the newspapers for not giving him credit for something. It would help us to know who they consider their strongest suspect, chances are they have interviewed him or her already who did this and have the information buried under paperwork.

A cold case squad would help, I think I saw a team of retired cold case police officers who go around the country and review cases if requested listed on the Internet. In judging MCPD I doubt they would request it, but her family could.

You may be referring to the VIDOQ (sp ?) Society. They are a global cold case squad based in, I think, Virginia. They do have a website. I just read a book where they took a cold case in Lubbock, Texas and were instrumental in prodding detectives down viable tangents. The case was solved, though the body of the victim was never recovered. Mason City LE need only to contact them and present the knowns. Vidoq would then accept/decline. Actually, it was the father of the victim in the Lubbock case that did the initial contact. He had worked along with the detectives on the case and knew all the facts, except, of course, who the perpetrator was.

I thought this was worth a bump.

I cannot understand the reasoning in having a fifteen year old case classified as active.

How long will this case be active?

20 years?
40 years?
75 years?
100 years?

IMHO the handling of this case defies logic. Unless having the case classified as active prevents any outsider getting access to the investigation files.
