Police shine their flashlights as they check the perimeter of the Stearns' house.

And then they prepare to enter.

From body camera footage, we can see it's very dark outside.

There are just a few glimmers of distant light coming from porches throughout the neighborhood.

The street's quiet and residential.

It has sidewalks and modest homes with short driveways and fenced-in yards.

The Stearns' house is white with black window shutters.

Sarah and her father both grew up in this house, where police are now knocking.

But no one answers.

A jumper.

It's an early theory, perhaps the most obvious for why the car might have been left on the bridge in the middle of the night.

Maybe the driver parked, then climbed over the edge.

Before walking into the house, officers worry someone might be home.

Mike.

Michael Stern.

That's Sarah's dad.

The front door is unlocked, and they head inside.

The home is mostly dark, but there's a small lamp and overhead light on in the living room.

A big dog is locked in a crate.

It's Buddy, Sarah's 10-year-old foxhound.
