A Santa Rosa man convicted of killing one cousin and trying to kill another during a family dispute has been sentenced to 18 years in prison, the Sonoma County District Attorney’s Office said. Isidro Godinez Flores, 31, was convicted in April of voluntary manslaughter of 32-year-old Jose Chavez and attempted voluntary manslaughter of 25-year-old Julio Chavez on Jan. 24, 2009. Flores had an argument with Julio Chavez in an apartment complex in the 900 block of Aston Avenue in Santa Rosa where Julio and Jose Chavez lived, the district attorney’s office said. After Julio was threatened, he called Jose Chavez and asked him to come to the apartment because there were “going to be some problems”, District Attorney Stephan Passalacqua’s office said. Flores left, drove home, got a knife and returned to the apartment. Jose Chavez armed himself with a sword when he saw Flores outside the apartment and confronted him, the district attorney’s office said. During the ensuing argument, Flores, who was seated in his truck, fired several shots at Jose Chavez. When Chavez fell, Flores got out of the truck and shot him in the head, the district attorney’s office said. Flores then chased Julio Chavez and shot him several times causing great bodily injury, the district attorney’s office said. Jose Sanchez died at Santa Rosa Memorial Hospital on Jan. 29 and Julio Sanchez survived. Flores was arrested Jan. 25 in El Monte during a traffic stop. Flores faced 29 years in prison, the district attorney’s office said. The jury found he personally used a firearm and inflicted great bodily injury.
