Hi, Park enthusiasts. I'm your host, Dilya DeYembra.

In the case I'm going to tell you about today is one that I have a feeling will resonate with many of you listening.

I'm talking specifically to those of you who have had the adventurous itch to travel internationally by yourself.

To explore some of the most remote or exotic places, completely independent of family or friends.

Feeling confident that the company of strangers and nature is the only thing you need.

Some of us are simply wired this way. Some of you might be like Aubrey Sacco, a 23 year old woman from Colorado who set out on a journey through the Himalayan Mountains in April 2010.

Never to be seen again. Her disappearance has baffled her family for over a decade and despite several people at one point being arrested for her abduction and murder.

No one is behind bars today and her family is still no closer to the truth.

Where she went, who she may have run into and why no one has seen her since she left for a week long hike 13 years ago remains a haunting mystery.

But maybe with your help that could change. This is Park Predators.

On Thursday, April 29, 2010, Connie Sacco went to check her email, expecting to see a message from her 23 year old daughter Aubrey in her inbox.

But nothing was there. Connie and her husband Paul hadn't physically seen their daughter for about six months.

Aubrey had been backpacking through South Asia since December 2009 and had been stopping in various villages across Sri Lanka and Nepal to teach English, art and yoga.

The last time they'd heard from her was on Tuesday, April 20. She told them she was planning to take a seven to ten day hike through Langtang National Park in northern Nepal.

And her plan was to touch base with them via email on the 29th when she returned.

Her plan after that was to catch a flight out of Nepal to Sri Lanka, then spend a week there before coming home to Colorado shortly thereafter.

But as Connie sat at her computer in the Sacco family home in Greeley, Colorado, staring at her empty inbox, she began to worry.

Not hearing from Aubrey was out of character. Usually she touched base over Skype or email every four days.

In all the months her daughter had been traveling alone, Aubrey had never ghosted or failed to make contact somehow.

Connie and Paul knew that no matter what, if Aubrey said she was going to connect with them by a certain date, she would.

According to an interview the couple did with the hosts of Lost in the Woods podcast, they said when Aubrey spoke to them before leaving for her hike, she told them her phone wasn't working.

So the best way for her to contact them would be through email when she found a lodge or shelter that had Wi-Fi.
