Is There a Serial Killer in Sao Paulo Targeting Gay Men?

Brazilian police are investigating whether a possible serial killer is behind the murders of more than a dozen gay men in a park in suburban Sao Paulo. Police chief Paulo Fernando Fortunato tells the O Globo newspaper that 13 gay men were killed there between February 2007 and August 2008. He says police are not sure whether a single person is responsible. Undercover police are now patrolling the park at night. [AP]
