I have 15 years of experience, and specialize in the field of crime scene reconstruction with specific knowledge in the areas of firearms, ballistics and shooting incident reconstruction. I have published on such topics as crime scene reconstruction, bloodstain pattern analysis and shooting reconstruction. I have testified 99 times on topics such as crime scene reconstruction, traffic accident reconstruction and photogrammetry. I received a ‘police officer of the month’ award for reconstructing a homicide in which a man beat his girlfriend to death after chasing her throughout the house. My detailed reconstruction showed that the defendant’s claim of self-defense was false.
