Mark Spawn has extensive experience in fingerprint identification from the detection and development of latent fingerprints to preservation, documentation and comparison. Mark Spawn has performed fingerprint work for crimes including burglary, robbery, larceny, arson, sex crimes and murder using traditional powder, chemical and forensic lighting techniques. He has also examined fingerprints for the identification of fugitives, persistent felony offenders, and deceased persons. His research into the effect of fire on fingerprint evidence included work conducted at the New York State Academy of Fire Science in which fingerprints were scrutinized after undergoing realistic fire and explosion environments. Through Spawn’s research it was found that in some instances fingerprint can survive the effects of fire. Most notable in Spawn’s research was a discovery of the etching (fingerprint baked into the surface, becoming durable) of a fingerprint into a metal surface.
