The Killer of Lake Tangyanika - Part Two
THE DEVIL WITHIN GUSTAVE — Episode Two: Built to Kill What makes a predator perfect? In Episode Two of our three-part investigation into Gustave, we leave Lake Tanganyika behind for a moment and travel to Tsavo, Kenya, in 1898, where two maneless male lions began pulling railway workers from their camps. The animals that became known as the Ghost and the Darkness terrorized the Uganda Railway project for months before Lieutenant Colonel John Henry Patterson finally killed them. More than a century later, their preserved remains would give scientists something Patrice Faye never had with Gustave: a killer they could actually examine. Then we go inside the Nile crocodile. Calling Gustave a dinosaur isn't scientifically accurate, but crocodilians belong to an evolutionary lineage whose basic predatory strategy has survived for an extraordinary span of time. Eyes and nostrils positioned above the water allow the animal to disappear almost completely beneath the surface. A muscular tail provides explosive acceleration. Armored osteoderms protect the body. Conical teeth seize rather than chew. And when prey is too large to swallow, the infamous death roll can tear it into manageable pieces. Everything about the design is built around one principle: Don't waste energy. That principle makes Gustave's story considerably stranger. Crocodiles are ectothermic ambush predators capable of waiting extraordinary periods between meals. They don't need prolonged pursuit. They wait until an animal enters the narrow strip of geography where water meets land—and then patience becomes explosive violence. For people who depend upon Lake Tanganyika for fishing, bathing, washing and drinking water, that kill zone is also an unavoidable part of everyday life. But Patrice Faye encountered reports of victims attributed to Gustave whose bodies were recovered or only partially consumed. That helped create the sensational legend that Gustave killed for pleasure. The biology tells a more complicated story. Crocodile ecologist Alison Leslie rejected the idea of a crocodilian psychopath. Attacks can be interrupted. Crocodiles can behave territorially. Large prey may be consumed over several days. And some of the deaths attributed to one famous crocodile may have belonged to entirely different animals. Faye nevertheless wondered whether decades of conflict in Burundi and neighboring Congo had provided Gustave with opportunities to scavenge human remains—and thereby learn that humans were simply another available food source. It remains a hypothesis, not an established scientific explanation. Finally, we meet the Old Man of the Lake. Faye estimated Gustave at approaching twenty feet long and perhaps a ton in weight. His enormous body carried distinctive scars, including wounds Faye believed came from gunfire, allowing him to distinguish Gustave from other crocodiles. After decades of survival, this wasn't simply a giant animal. It was an experienced predator capable of learning the repetitive patterns of the people living along its territory. Perhaps Gustave wasn't terrifying because he broke the rules of nature. Perhaps he was terrifying because he followed them perfectly. And Patrice Faye had finally decided that understanding Gustave wasn't enough. He was going to catch him.
