No, we didn't make this guy up.
Why You Might Meet Him Anyway:
After being sentenced to a mental institution in Uzbekistan and escaping once, the government decided that less than 10 years of rehabilitation was enough for this serial killer and simply let him go.
So Where Is He Now?
Very little is known of Dzhumagaliev's current whereabouts, though he is said to be living with his relatives in Eastern Europe. However, being a free man and all, he can travel anywhere he pleases. Perhaps a place where almost no one has heard of him. Like your town, for example.
Nikolai has always been described as a very charming and well-spoken man, and one not bad to look at to boot (which only helped him lure more women into his fridge). The Jaws teeth are, thankfully, a dead give away. But hey, he could totally blend in at a James Bond convention. Unless he keeps his mouth closed, in which case he could blend in anywhere at all. Your basement, for instance.
