Ex-Riverside County Sheriff’s deputy Oscar Rodriguez was sentenced in a Riverside County courtroom for the voluntary manslaughter of his girlfriend’s former partner while on duty in January 2014. A former Riverside County sheriff’s deputy was sentenced to serve a year in jail for killing his girlfriend’s former partner while on duty. AdvertisementOn Tuesday, Riverside County Superior Court Judge Otis Sterling III sentenced Rodriguez to a one-year jail term and 10 years of probation. The evidence in the case showed that “this Riverside County sheriff’s deputy engaged in reckless and unlawful conduct,” Greenfield said in an emailed statement. “The conviction confirms what we proved then, but the sentencing was not commensurate with the malicious conduct of this deputy and reflects the broader attitude of Riverside County and the Riverside County sheriff toward accountability,” Greenfield said.
