Kayla Brantley

More than 50 years after she vanished without a trace, a teenage girl's murder has finally been solved.

And the man responsible?

One of the most notorious serial killers in American history, Ted Bundy.

Laura Ann Amy was just 17 years old when she left a Halloween party in Utah in 1974, telling friends she was stepping out to buy cigarettes.

She never came back.

Her body was found weeks later, but for decades, her case remained officially unsolved, despite Bundy confessing to her murder before his execution.

Now, in a major forensic breakthrough, DNA evidence has finally confirmed what many long suspected, and it's raising a chilling possibility.

If this case took more than half a century to close, how many more victims could still be out there?

To take us through this, from the new DNA breakthrough to what it reveals about Bundy's crimes, I'm joined by Daily Mail's senior crime correspondent, Rachel Sharp, who's been reporting on the story.

This is The Trial USA.

I'm Kayla Brantley.

We'll be back in just a moment.

Rachel, Ted Bundy is one of America's most prolific serial killers.

He was known for being very handsome.

And because of that handsome charm, he attracted women that he would then murder.

Can you walk us through Ted Bundy's profile?

Who exactly was he and what do we know?

But one thing that we do know is that he confessed to at least 30 murders, and one of those...

murders is Laura and Amy, which is, you know, the subject of this episode.

How did he confess to that specific murder on his deathbed in 1989 when he was executed?
