Before moving on to other suspects whose names were coming in via phone calls and letters

from the public, investigators knew what they had to do next.

Give Ron Holtz another polygraph test.

I say another because they actually gave him one just three days after darling's abduction,

which he passed.

And listen, Ron was never a suspect.

But back then, officers knew that they had to play offense and defense, and if this case

were to ever go to trial, police knew that Ron would be an easy target for a defense

attorney.

So, they had to formally rule him out, not just as a suspect, but of any involvement.

Plus, talking with Ron was a great way for investigators to learn more about darling.

As far as bad habits, the only one I ever got around was the fact that at night she never

pulled the drapes or pulled the shade down.

She just thought that we lived out in a remote area.

She butty that's out there is going to be sick anyway, and if I went into the bedroom

first was going to shower or something, then I always pulled them down.

She never did.

She never did.

And I just wonder now if there's been someone looking all along or what?

Up to this point, they had kind of skimmed over Darling's lifestyle and personality, because

A, nothing really stuck out as a red flag.

And B, they were hot on the trails of Danny Bender, Robert Zabrowski, and Ricky Mock.
