• Scene examination: Investigators will return to the site to document the scene with detailed measurements and photographs. They will analyze evidence such as skid marks, impact points, and debris, which may have been overlooked or misinterpreted during the initial police investigation.
• Vehicle forensics: For vehicle-related accidents, PIs can perform an advanced forensic examination of the vehicles involved. They assess the extent and consistency of the damage, inspect mechanical systems for potential failures, and use crash data retrieval (CDR) tools to extract "black box" data from a vehicle's internal systems.
• Witness interviews: Private investigators are skilled at locating and interviewing witnesses who may not have been found by police or who have additional information to share. These statements can offer crucial supporting details that were not included in the official police report.
• Surveillance and digital forensics: For personal injury cases, private investigators may conduct surveillance or monitor social media to verify a claimant's stated injuries and limitations. This helps insurance companies and legal teams detect fraudulent or exaggerated claims.
• Recreation and analysis: Using specialized software and techniques based on physics and engineering principles, investigators can create detailed models or 3D reconstructions of the incident. This helps visualize the sequence of events, calculate vehicle speeds, and determine contributing factors. 

Hiring a private investigator can be highly beneficial in several situations, including:
• Contested liability: If a party disputes fault for an accident, an investigator can provide an objective, fact-based analysis to support your claim.
• Insufficient evidence: If the police report is incomplete or lacks crucial details, a private investigator can help gather additional evidence to strengthen your case.
• Suspected fraud: Insurance companies regularly hire private investigators to investigate suspicious or potentially fraudulent claims.
• Unclear circumstances: In complex cases where the cause of the accident is not immediately obvious, a PI can piece together the puzzle and provide a clear picture of events.
• Preparation for trial: A professional investigation produces credible, court-admissible evidence that can be presented during negotiations or at trial. 

The cost of hiring a private investigator for accident reconstruction varies based on several factors, such as: 
• The complexity of the case
• The amount of time required
• The investigator's experience and qualifications
• Travel and equipment costs
• Report preparation and expert testimony in court
