Please be advised. In April 2014, 2014, Anaheim Police Detective Julissa Trapp took one of her partners,

J.D. Duran, and headed 13 miles north to Brea.

She goes, we're going to the lane.

Yeah, I'm all about the big dig. I mean kind of you had me at hello type of thing.

The Olinda landfill is a fake mountain that grows by 7,000 tons a day at Orange County's northern tip just before it turns into

Los Angeles County.

You drive up there winding around, coming around a few times, switchbacks, and you get up to see this large expansive land.

I mean, it is just huge.

It's the end point of much of the trash generated by Orange County's 3 million people,

a marvel of engineering and efficiency in the quest to

return inconceivable volumes of solid waste as near as possible to their constituent molecules.

The detective stepped onto the dirt of the 565 acre site, high level with the clouds.

They stood on a football field-sized plateau of active dumping.

This is called a cell. It was built atop countless other

densely packed garbage cells decades deep. Somewhere in the mountain the

detectives believed lay the remains of four women.

What is going to be the feasibility of trying to dig to find these girls?

J.D. and I were clueless. We had to find these girls.

J.D. and I were clueless. We had no idea the task it was going to be. Like, we were just so gun-ho, yes, we're going to dig, like, how could we not? Like, yes, we're 100% we're in.

They knew when the four women had disappeared.

This allowed the landfill officials to estimate where the bodies might be.
