Paige had an explosive, troubled history with Dixon.

They might not have known exactly where to begin.

But Paige's family knew they'd have to start somewhere if they were ever going to find her.

So Craig and Callie Bergfeld set off in one direction.

Good luck today.

Thank you.

Hopefully we'll find her today.

And Frank Bergfeld headed off in another.

While the Bergfeld family searched for Paige, the sheriff's department continued its own investigation.

Deputies brought in specialty divers to search the river.

And they got one of their first big leads in the case when someone called 911 after seeing a car in flames parked in an empty lot.

It turned out to be Paige's car, the car she was driving when she disappeared.

The next morning, authorities discovered that the fire was started from inside the car on the passenger side.

DA Pete Houtsinger.

And the realization of what that might mean for his daughter was too much to bear.

while Paige's family clung to hope that she was still alive.

Investigators turned their attention to Paige's second ex-husband, Rob Dixon.

Paige met Dixon in 1997, and back then, he seemed like a real catch.

It was a whirlwind courtship, and the following year the two had a wedding and started a family together.

But Dixon had extravagant taste, and he was reckless with his money, investing millions of dollars in risky business ventures.
