Before we begin today's episode of Australian true crime, I want to tell you about a new project

we've been working on behind the scenes. It's called She Matters. It's a new podcast from

award-winning journalist and femicide researcher Shirel Moody. Each week, Shirel speaks with

families of women and children killed in Australia, sharing who they were, the joy they brought,

and the love they left behind. She Matters isn't a true crime podcast. It's about lives lived, lives loved and lives

lost. She Matters is produced by Dashmade podcasts in association with bravecasting media.

She Matters is available wherever you get your podcasts.

Everybody absolutely loved her.

I had the highest, have the highest regard and respect for her.

but because she was the fourth woman to be murdered there that year, Yosemite, it seemed, had been the hunting ground of a serial killer

for at least six months. Then suddenly, just 48 hours after Joey Armstrong's murder, the FBI announced it had a suspect in custody and a confession.
