Prosecution evidence in Rhode Island DUI injury and death cases typically includes the arresting officer's testimony, field sobriety test results, BAC test results from breath or blood, medical records documenting victim injuries, accident reconstruction reports, witness statements from other drivers or pedestrians, body camera and dashboard camera footage, 911 audio, and toxicology expert testimony. Cases involving fatalities often include extensive expert witness testimony on the cause and timing of death. The defense reviews each evidence category for procedural defects, chain of custody breaks, and credibility challenges. The volume of evidence in these cases is significantly higher than typical misdemeanor DUI cases.
