Erin Moriarty

It was a bond she had had with Molly ever since the day she was born.

I do remember thinking that, oh, that baby is my baby, too.

I'm going to teach her everything I know, and we're going to do this life together.

Molly also had a close relationship with her brother.

She very much wanted to be like my brother.

Molly was 5'7".

You know, she was athletic and in shape and strong.

So when police suggested that Molly could have drowned, they didn't believe it.

When Molly went missing, I mean, it was inconceivable.

Adding to the mystery, the police radio was there, but Molly had not used it for her required morning check-in.

Why?

So what was, what happened?

Later that afternoon, when it became clear to local police that Molly had not just walked off with friends.

State police took over the investigation and launched an extensive search.

Massachusetts State Police Lieutenant Colonel Dan Richard headed to Warren to help out.

Also present at the scene was then Worcester District Attorney John Conte.

The state police are working around the clock on this, okay?

Detectives zeroed in on everyone who was close to Molly, including family members, friends, and Molly's boyfriend, Steven Lucas.

They'd only been dating for three months and had just gone to the prom together.
