Guaratuba, Brazil

With a population of just 17,998, Guaratuba is hardly a bustling metropolis. This sleepy coastal town is mired in one of Brazil's longest and most infamous legal cases - the Guaratuba child murders that rocked the community in 1992. Though the case has since been the subject of extensive media coverage, the bureaucratic headaches and lingering public safety concerns it has spawned are very much a persistent reality for locals.

Whether it's the tortured confessions, alleged political meddling, or the gruesome details of the murders themselves, Guaratuba's dark history casts a long shadow. Those seeking a peaceful seaside retreat may want to look elsewhere, as the weight of this unresolved tragedy hangs heavy over the town.

Guaratuba is not for the faint of heart.
