A case of vehicular homicide was settled Wednesday over the protests of a mother who says a paltry one-year sentence pales in comparison to her daughter’s life that was snuffed out by the impaired driver.Meanwhile prosecutors say they were fortunate to work a deal where the defendant will serve nearly a year behind bars and that he faces 12 years in prison if he doesn’t live by the letter of the law.“He violently killed her,” Gina Lance, mother of Ashlyn Barnes, said after her daughter’s killer was allowed to enter a guilty plea over her protests Wednesday morning. “It’s ridiculous. Justice wasn’t done for my daughter.”Lance is angry that prosecutors allowed Ramiro R. Ibarra, 20, to enter guilty pleas to charges of vehicular homicide and vehicular assault in a deal in which he will be required to serve one year of a 12-year sentence.
