In order to convict somebody for car manslaughter, the district attorney needs to prove that the offender committed every component of the criminal offense by proof beyond an affordable doubt. The aspects are detailed under the criminal statute that describes car manslaughter. One aspect might be that the offender was under the influence of drugs or alcohol. In addition, the district attorney may need to prove that the accused committed a crime or an act that was lawful but hazardous. Some states need the defendant to have committed some independent risky act rather than only revealing that the chauffeur suffered. The driver’s carelessness must have been the direct cause of death. The prosecution might count on a range of evidence to help develop problems, such as arise from a blood, urine or breath test, eyewitness testimony, a confession by the offender and invoices that reveal alcohol purchases near the time of the mishap.
