The problem is they have no evidence that the fault was with Chris Soules, additionally, he didn't technically leave the scene because he called gave them his information and didn't leave until emergency vehicle arrived. So the prosecution can't say him leaving the scene resulted in the guy's death just because the police hadn't arrived. So I think it is right for the defense to challenge the judge's decision to factor in the guy's death in sentencing. Do some of his actions look suspicious? Yes, but without more it doesn't seem like the judge made the correct call. In addition, him pleading down had nothing to do with Soules being 'famous', it was because they didn't have a strong case.
