I recently retired from a 20 year career in law enforcement where I specialized in criminal and auto collision investigations. I was a detective assigned to a team that handled everything from petty theft to homicide investigations. I earned a specialty certificate in homicide investigation. I was the lead investigator for a multi-agency major/fatal accident response team. I have testified as an expert witness in California Superior Court on accident reconstruction and Forensic Mapping. I was a District Attorney Lead Investigator on many cases and have extensive courtroom experience.
