I told you back in episode 11 that there was a pool of people Cass County was working their way through at the same time that they honed in on Steve.

Or rather, Detective Dave Gizzy told you.

In your right hand, you had a pool of people that could possibly be, and then you would take them out

if you could get an alibi or a polygraph or whatever, and then you move them over to the other

hand that they're no longer involved. Their name's still in a report. They're still actively

listed in the case, but at that point we weren't focusing on them.

The problem is there's hardly anything in the case files explaining how or why certain

people were dismissed or if they were properly investigated at all.

An exception to that is Ada's husband, Ed Herodine.

His road from suspect to collateral victim is fairly well documented.

By the time Ada's remains were found, police weren't really interested in him anymore.

But they still had him take another polygraph, his third, which he paid for.

When he passed it, he was checked off the list for good.

Of course, his brother-in-law, Larry's Sarhat, who

continued working the case alongside investigators, had already mentally done that from day one.

Even Ed's forgetfulness during police interviews might have a simple explanation. He was reportedly

a very heavy drinker, and that didn't stop after he lost his wife.

Either way, no one we've spoken to believes that he was involved.

But with other suspects, things aren't so straightforward.

That doesn't necessarily mean the work wasn't done, because as I mentioned before,

despite all the records we managed to get, there are lots of gaps due to missing reports

or things that weren't documented.
