The news of a second decapitation this year in Brazil has raised questions about whether such heinous crimes may deter foreign visitors considering a trip for next summer's FIFA World Cup.

João Rodrigo Silva Santos, a former Brazilian professional soccer player, was kidnapped and brutally decapitated this week in the city's West Zone. His wife, Geísa Silva, an officer in one of Rio's Police Pacification Units (UPP), found his head in a backpack left on their front door step in the early hours of the morning.

Less than four months ago, details of another gruesome decapitation made international headlines. In the rural interior of Brazil's northeastern region, a referee at an amateur soccer game was decapitated by angry spectators after he stabbed a player who refused to leave the field. The player died on the way to the hospital.

The violent crimes come as the country prepares to host two global sporting events: the World Cup in June and the 2016 Summer Olympics. But Brazilians don't view the cases as a reason for visitors to stay away.

"Unfortunately that kind of bad news is what's transmitted abroad," says Felippe Trindade, a 29-year-old Rio native and soccer fan who lives five blocks from Rio's iconic Maracanã Stadium. "I believe that for foreigners it causes a hugely negative impact."

Violent crimes such as this week's beheading garner significant international media attention, but violence can take on a different nature in other parts of the world, says Bruno Monteiro, 26, who is also a local soccer fan.

"People outside Brazil see news like this and think, 'Whoa look at how they live in Brazil, it's so violent, what a bizarre place to live.' But I have the same thought when I see news about people shooting children in elementary schools."

Monteiro says the stereotype of Brazilians being passionate about soccer is true. He points to two kinds of fans.
