Graham left the scene after calling his wife.Blanchard, 27, died about a week later from his injuries.Graham will be sentenced June 15. Deputy Prosecutor Jeannie Bryant said Graham faces a sentence of either 4 1/2 years or 10 years in prison, depending on a dispute over his number of prior convictions.As part of a plea bargain, prosecutors dropped a vehicular homicide charge against him, Bryant said. The bail-jumping charge relates to Graham missing a court hearing last year.Defense attorney Gregg Schile said he plans to request that Graham participate in the Drug Offender Sentencing Alternative program, which combines treatment with the sentence. Graham told the judge he struggles with methamphetamine addiction and alcoholism.
