Mexican authorities say they have found the bound, asphyxiated bodies of five men and a woman in the Pacific coast resort city of Mazatlan.

The prosecutors' office for the cartel-plagued state of Sinaloa says the killers wrapped the victims' heads in duct tape, covering their mouths and noses and smothering them.

The six bodies were found Sunday dumped behind a private medical clinic. Their hands had also been bound.

The victims were residents of Mazatlan. Three were abducted from a store parking lot Saturday by armed men in two vehicles, and the others were kidnapped from a street in front of their home.

Mazatlan has been trying to revive its tourism industry after violence drove many visitors away.
