The cops are on record as saying the condition of Jodi's apartment looked suspicious right from the start, yet don' t elaborate. Why aren't they more specific?

Can DNA be collected from a top suspect through a discarded coffee cup, for example, and compared with any DNA found on those beer cans found in Jodi's kitchen sink, or from fingerprints from the upraised toilet seat?

Could the palmprint on her car not be compared with ones on items listed above? 

Is the name a witness heard a woman yell at the time Jodi disappeared, the same as the name her assistant speculated on?

The assistant gives cops 1 out of 10 for their investigative work?  Why so low?

Then she implies that Jodi was on drugs.  I doubt she would buy them from a dealer firsthand given her profile, so who was buying them for her?

This is a terribly frustrating case because people make the most extraordinary statements, then don't provide specifics.  Do they know the killer and fear the too may be harmed?  This would include the witnesses who didn't call 911.

Seems to me the question is who had motive, means, and opportunity and lived close enough that he knew he could take his time.

Also, where did the trail of Jodi's items stop? In the middle of the parking lot, or closer to the perp's possible apartment? The key was bent in the car lock so it certainly seems the struggle began there.

Why have cops not been aggressive enough in collecting evidence to establish a chain of evidence?

Would be curious about what other's think.

Is it really so unsolvable that the perp has to slip up, or confess?

Sad.
