Brazil Police Hunt for Possible Serial Killer Targeting Gays

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.

Fortunato says he went public with the investigation to help warn people of the danger.

His comments were published Monday. Requests for police comment were not immediately answered.
