Hi there, 2020 listeners. It's Jeffrey Roberts. This week, we're dropping a new true crime

investigative series into your feed from our colleagues at ABC Audio. It's called radioactive,

the Karen Silkwood mystery. It's all about the country's first nuclear whistleblower. 50 years ago this week, Karen Silkwood died in a fatal car crash.

Her life and the circumstances around her death continue to grip the nation.

Here's episode one, The Tapes.

The Tapes. Last year, my buddy Mike and I found ourselves inside a giant warehouse with hundreds of big wooden storage containers stacked floor to ceiling.

It felt like a scene from an Indiana Jones movie.

You know, the one where the government stores the Lost Ark

in a massive warehouse filled with crates where it'll never be found.

Well, we were definitely searching for lost treasure,

hoping one of these storage containers would hold the key to a 50-year-old mystery.

Okay, it's coming out.

We pulled out box after box, each one sealed with layers of thick packing tape.

There were boxes of toys and old family photo albums and a somewhat creepy ventriloquist dummy.

Let me get this out of the way. I can't see what it says.

And then...

Mike, you found it.

What?

Silkwood storage.

The very last box in the very back corner. Biggest that was. Holy cow I got goosebumps. On the outside in Black Sharpie was the name,

Silkwood. Yeah, it's all here. Holy me. This is what we'd been looking for, hoping for.

Cassette tapes recorded in the 1970s.
