In late 2007, the remains of a young woman from the caska nation were discovered in the Yukon woods.

I always think about I want to know what really happened.

So I travel north to try to understand what happened and who was involved.

It's a pretty big risk to come forward with the information that I have.

I'm David Ritten and this is someone knows something season 8, the Angel Carlet case, available now.

This is a CBC podcast.

Hello, my name is Poonham Tunager.

I'm an investigative journalist working for BBC News in London, specialising in race, security, human rights and global affairs.

I want to tell you about my new podcast, Bloodlines, a co-production between the BBC and CBC podcasts.

In 2018 in Syria, ISIS is on the brink of defeat.

Two-year-old Salman disappears amid the bombardment.

In London, his grandfather desperately searches for answers.

After the war against the Islamic State was won, what became the children of its fighters?

There are thousands of kids like Salman, with roots in Canada, the UK, the US and beyond.

Some of whom are still trapped without a way back home.

I've covered the ISIS story for many years.

And in this podcast, I embark on a dangerous journey to find out what happened to Salman

and all the kids like him left behind in the Syrian desert.

Now, here's the first episode of Bloodlines.

See, hello.

I love you.

Daddy.
