Each investigation is tailored to the circumstances of the loss, available evidence, and the questions that need to be addressed. Services range from initial site examinations through laboratory testing, technical analysis, and reporting.
Structure Fire Investigation

Determine fire origin and cause by examining fire patterns, ignition sources, electrical systems, appliances, and physical evidence.
Vehicle Fire Investigation

Determine vehicle fire origin and cause by examining burn patterns, electrical systems, fuel systems, components, and physical evidence.
Water Loss Investigation

Determine water loss origin and cause by examining plumbing systems, appliances, connections, materials, damage patterns, and physical evidence.
Mechanical Failure Analysis

MEET KIRK LUMAYE
Engineering Knowledge. Investigative Experience.
Bona Fide Forensics is led by Kirk LuMaye, a licensed Professional Engineer and Certified Fire & Explosion Investigator with more than a decade of experience investigating fires, water losses, and mechanical failures.
With a degree in mechanical engineering from California State University, Sacramento, Kirk brings an engineering perspective to questions about how products and systems fail—and how those failures contribute to property losses.
His experience includes scene investigations, component examinations, technical reporting, and expert witness testimony.
“Our mission is simple: Seek the truth through honest and thorough investigation.”
— Kirk LuMaye, PE
FROM EVIDENCE TO ANSWERS
Clear Findings. Preserved Evidence.
A useful investigation connects the physical evidence to the questions that matter. We evaluate potential causes, consider alternative explanations, and explain what the available evidence supports.
Our work helps clients assess claims, potential subrogation opportunities, and disputed technical issues. Conclusions are communicated clearly, including relevant limitations and unresolved questions.
Services may include:
✓ Scene and component examinations
✓ Evidence collection and preservation
✓ Joint examinations and testing
✓ Engineering analysis and written reports
✓ Deposition support and expert testimony
The scope of each assignment is tailored to the loss, available evidence, and questions being evaluated.
