In October 1977, one of Australia's most celebrated designers — Florence Broadhurst, the woman behind some of the country's most iconic wallpaper — was found beaten to death in her own Paddington warehouse. The front door had been open all night. There was no sign of forced entry, no struggle... and two clean teacups sitting in the kitchen.

Forty-seven years later, no one has ever been charged.

In this episode of Criminology Files, we go beyond the headlines to actually interrogate the case: the estranged son with a public argument and a verified alibi, the mystery visitor who shared tea with Florence hours before she died, and the infamous theory linking her murder to convicted serial killer John Wayne Glover — the "Granny Killer." We break down staging vs. posing, why proximity bias skews cold-case theories, and why "resembles" isn't the same as "proven."

This is a story about a woman who spent her life curating her own myth — and a death that's remained just as unresolved.

The Killer Cadets

They were teenagers with extraordinary futures ahead of them.

David Graham was headed for the U.S. Air Force Academy. Diane Zamora was bound for the U.S. Naval Academy. They were young, ambitious, admired — and engaged to be married.

Then came a lie.

In 1995, sixteen-year-old Adrianne Jones was found murdered in a field outside Grand Prairie, Texas. She had been beaten and shot, and at first, investigators had almost nothing to explain why she had become a target.

Nine months later, the case suddenly broke open.

A confession from a Naval Academy dorm room led investigators back to Texas, where they uncovered a story of jealousy, loyalty, manipulation and murder.

David and Diane eventually confessed. But when their cases reached court, their stories began to tear apart.

And then came the revelation that changed the story entirely:

The affair that was supposedly the reason Adrianne Jones was murdered may never have happened.

The Killer Cadets examines the murder of Adrianne Jones, the relationship between David Graham and Diane Zamora, their confessions and convictions, and the criminological questions surrounding a crime that began with a lie and ended with two teenagers serving life in prison.

This is a story about loyalty taken to its most devastating extreme — and about a sixteen-year-old girl who became the victim of a conflict that may never have been hers at all.

Listener discretion is advised. This series discusses the murder of a sixteen-year-old girl and includes descriptions of violence.

In 1995, two honor students at the top of their class — bound for the Air Force Academy and the Naval Academy — committed a murder that shocked Texas.

16-year-old Adrianne Jones was found dead in a field outside Fort Worth. It would take almost a year, a jealous confession, and a betrayal between two people who claimed to love each other more than anything, to unravel what really happened that night.

This is the story of David Graham and Diane Zamora — two "perfect" teenagers whose secret would define the rest of their lives.
