Durango state security chief Javier Castrellon Garza says the initial report on the Saturday incident said three men had been wounded near San Jose de Viborillas. He said all three later died while being transported to a hospital.
Castrellon said investigators then turned up seven more victims. Of those seven, he said, three belonged to one area family and four to another. He said at a news conference yesterday that authorities were still trying working to identify the first three victims.
