The Killer of Lake Tangyanika - Part One

THE DEVIL WITHIN

GUSTAVE: THE KILLER OF LAKE TANGANYIKA

Episode One — Pattern

For years, people living along the shores of Lake Tanganyika told stories about something enormous moving beneath the water. Fishermen disappeared. Bodies were recovered bearing catastrophic injuries. Survivors described attacks that happened with terrifying speed, often in places where generations of Burundians had fished, washed clothes and collected water.

Then French naturalist Patrice Faye began looking for a pattern.

Faye was an unlikely investigator: a self-taught naturalist and herpetologist from Lyon who had worked as a plumber and lumberjack, traveled through Africa and eventually made Burundi his home. During some of the country's darkest years, he developed an extraordinary knowledge of its wildlife—and became increasingly troubled by the stories emerging from Lake Tanganyika.

In Episode One of our three-part investigation into Gustave, we travel deep into the history of Burundi, a breathtaking country scarred by colonialism, political assassination and a civil war that killed an estimated 300,000 people between 1993 and 2005. Against that backdrop, Faye developed a disturbing theory: could years of human bodies entering the region's waterways during the violence have taught an opportunistic predator that human beings were food? It was a theory he could never prove, but one that connected Burundi's human tragedy to the mystery developing along its shoreline.

Faye collected eyewitness accounts, compared locations and studied descriptions until he became convinced that many of the attacks were connected. Witnesses repeatedly described extraordinary size and distinctive scars, including an injury on the animal's head. Eventually, Faye saw his suspect himself and gave him a name: Gustave.

Gustave wasn't a man.

He was an enormous Nile crocodile—estimated by Faye at roughly twenty feet long, perhaps a ton in weight and around sixty years old, although the animal was never captured and scientifically measured. And while the sensational claims that Gustave killed two or three hundred people belong more comfortably to legend than established fact, something very real remained beneath the mythology: an exceptionally large, scarred crocodile that Faye would spend years trying to understand.

This is the story of a naturalist, a country haunted by war, and a predator that became a legend.

This is Gustave: The Killer of Lake Tanganyika.
