Murdered Ohio woman Janice Hartman’s case key to solving mystery on ‘Dateline’

(NBC News) — On Friday’s all-new two-hour “Dateline,” when New Jersey woman, Betty “Fran” Gladden-Smith, goes missing, investigators uncover her husband’s chilling history, including dark secrets about another missing wife, Janice Hartman from Ohio.

Would John Smith be caught before he put another woman in danger?

Here is a preview of Andrea Canning’s report:

There was one face he showed to the world.

SHERRIE DAVIS: John was great with my mother and my grandmother.

SUMMER HATHAWAY: He was really, really nice.

But there was another side — an evil one.

DEANNA CHILDERS: I said, “John, where’s my mom?” He said, “I thought she was with you?”

One week had turned into two and no one had heard from Fran Smith.

DEANNA CHILDERS: I was absolutely panicked because I knew something was really wrong.

John Smith’s life appeared to be full of secrets.

DAVE MANSUE: Things are starting to snowball here.

BOB HILLAND: I had no clue what I was about to get involved with.

ANDREA CANNING: There’s another wife …

DEANNA CHILDERS: Missing.

A NDREA CANNING: … that’s missing.

SHERRIE DAVIS: Missing.

D EANNA CHILDERS: Another wife that’s missing, yeah.

MICHAEL DANSBURY: This can’t be a coincidence.

A case that was about to take a very dark turn.

BOB HILLAND: The new wife’s name is Diane Smith.

How long before the evil side struck again?
