Jane and Bob D'Ottick raised three kids and eventually settled outside San Diego,

but old issues often resurface when the kids leave the nest.

You know, the kids were seemingly gone quickly, almost all at once, and it was just Bob and I. It was just difficult.

And we did talk about divorcing. In fact, we actually filed and then decided after living apart

for a short period of time that we wanted to go to therapy and we wanted to work this out.

We were together for 30 years. We truly loved each other and wanted to kind of honor this new

phase in our lives. They managed to bounce back and reinvent themselves. Bob even took up running

in marathons, occasionally inviting his daughter Claire along.

To me, that was like, what incredible modeling for a parent.

You know, like this is a hill, like any hill you might face in life.

And you can make it to the top.

Both Jane and Bob continued to model that can-do spirit through Valentine's weekend 2000.

We had a stay-at-home, give each other gifts, make a little cake, and a fancy meal Saturday night.

The next day, Bob went out for a run and never returned.

And I'm the one that invited the detectives into the house,

so we don't need a search warrant.

We're welcome in here.

And look at everything.

Help us find these answers.

And it appears that a witness came forward with a lead

that pointed at two unknown men.

But it seems the police went in a different direction.
