Anne-Marie Green

We don't know who's responsible for her murder.

48 Hours actually covered this case back in 2003.

Why revisit it now?

Yeah.

And, you know, Aaron, one of the things that we have noticed with some cases that have gone unsolved for even decades, you know, things change.

People get older.

They may decide to come forward.

So you never know who may remember something that they had buried that may help with this case once they hear about the hour.

So just to remind people, on the morning of June 27th, 2000, Molly's mom, Maggie, dropped her off at Cummins Pond after 9.50 a.m., where Molly was working as a lifeguard.

Shortly after that, beachgoers arrived, but Molly was not there.

Police were eventually called to the scene, but Maggie wasn't notified until Molly had been missing for three hours.

First question, why did they wait so long to tell her family that she was missing?

I've got to tell you, one of the things that sort of struck me, being the mom of a semi-newly-minted teenager, is that I was surprised she was working at the pond alone.

Right.

So here's the thing, though.

Once they determine that she's missing, I mean, they really do spring into action.

There's an extensive search that's launched.

Hundreds of tips start flooding in after police release a sketch.

It is a description that Maggie gives them of a man that she remembers seeing in the parking lot.

He has a white car with him and he's at Cummings Pond the day before Molly disappeared.
