Erin Moriarty

Heather, along with her family, were called to testify.

They say that many of the DA's questions seem to be focused on Molly's friends.

I remember we were all kind of like mad because we didn't feel like they were really significant.

We have a timeline.

And they were telling police conflicting stories about what happened in the hours before and after Molly went missing.

The grand jury transcripts are sealed, so it is not known whom the investigators actually questioned.

But they would later clear Steven Lucas as a person of interest.

After two long years in December of 2006, the grand jury was dismissed without an indictment.

Just weeks after the grand jury was dismissed, John Conte retired, and Joe Early Jr.

took over as Worcester District Attorney.

He says the grand jury was used as an investigative tool to preserve witnesses' testimony.

But Heather says not having answers as to who murdered her sister was taking its toll.

I was giving up hope in a lot of areas.

And things only got worse.

In 2007, her father, John Bish, who worked so closely with police, had a stroke.

Heather would now face the daunting task to take over where her father had left off.

And it would not be easy.

In 2008, a man who resembled the sketch, named Rodney Stanger, was arrested for murdering his girlfriend in Florida.
