The Mysterious Disappearance of Agnès Le Roux

This is a case that has gripped readers for decades. A young heiress linked to a storied casino vanished on an October night in 1977. The car she drove was a white Range Rover, and then she was gone.

I’ll walk you through why this story stands apart: there was no body, no clear crime scene, and a legal path that kept changing over time. You’ll meet Maurice Agnelet, a former lawyer and her lover, who moved from confidant to suspect and faced multiple trials.

Years of headlines, appeals, and a retrial in Rennes shaped public opinion. Agnelet died in New Caledonia on January 12, 2021; his son said he died in his sleep. That end closed one chapter, but many questions remain.

Read on for a clear timeline, the money trail, and how each development fed into the next. My aim is to make the facts easy to follow, like catching up with a neighbor over coffee.

Over time the funds moved into the lawyer’s sole control. Prosecutors argued that shift underpinned motive. Bank records became a steady guide when memories faded.

When an early alibi later collapsed, investigators reopened files and rechecked the flow of cash. Each review tightened the timeline around board votes, the share sale, and the days just before the disappearance.
