What makes a killer contains graphic details of sexual assault and violence and is not intended for all audiences?

Listener discretion is strongly advised.

When police began investigating the disappearance of Heather West in February

1994 it led them right to her parents front door.

Five days and nights into their excavation

and forensic teams have now unearthed three sets of human remains.

All buried in separate places, five feet under the garden patio of this Gloucester

home. Fred and Rosemary West are one of the most infamous couples in British history.

They sexually abused, tortured, and murdered young women, including their own daughter.

Children are their things to play with. They are disposable. They're things there to be used and abused.

For 20 years, Fred and Rose West satisfied their appetite for sex and murder inside their home on 25 Cromwell Street, Gloucester, which became known as the House of Horrors.

I've never for one moment doubted that Frederick West was a truly evil man,

but he found in Rose the perfect sorceress apprentice. This is what makes a killer, a 12-part series that chronicles the lives and crimes of the world's most notorious killers.

I'm your host, Jennifer Netoso.

In every episode, we'll trace a killer's origins, examine their

behavior, and follow their path to bloodshed. In this episode we'll discuss Fred and

Rosemary West. In 1969, 28-year-old Fred West was married to his wife, Rina.

Fred had a young family at home.

But he had his eye on a 15-year-old girl named Rosemary Letts.

Rose and her family had recently moved to the Gloucestershire area.

Jane Carter Woodrow is the author of Rose West,

the Making of a Monster.
