The snakeheads' arrival followed the simple script of a King novel, as well, with a careless mistake by an unthinking man, as detailed in a 2007 article in the Washington Post Magazine:
Around 2000, a man who lived in Crofton [in Maryland] had ordered two live snakeheads from an Asian fish market in New York, wanting to make his sister, who was ill, a pot of snakehead soup. But the sister got better before the fish hit the pot. The snakeheads, a male and a female, were set free in the pond. They made babies.
In 2002, an angler found a snakehead in a pond in Crofton, and local wildlife officials immediately pressed the nuclear button, poisoning the pond's waters in an attempt to make sure none of them wriggled their way to any other locales. The original two snakeheads had, in two years, multiplied to 800.
At last, the officials could exhale - the snakehead invasion had ended before it began. Or had it? Two years later, more of the fish showed up in a Maryland lake, and then others were caught in the Potomac River. Panic ensued, with lurid tales of giant Asian, air-breathing fish striding across land and devouring babies. The snakehead earned all manner of epithets (as if being called ‘snakehead' weren't bad enough): Frankenfish. Fishzilla. The fish from hell.
