The Evidence Trail
What really happens when forensic science meets real-world investigation? The Evidence Trail takes you behind the scenes of forensic investigations and the evidence that can help solve them. With over 15 years of experience as a Crime Scene Investigator, host Chris Gee has walked under the police tape and read the stories left behind. Now, as a Forensic Fire Scientist, he's following the evidence into a new world — where every scene has a story to tell. But he's not always alone. Investigators, scientists, forensic specialists and CSIs join Chris to explore the science, techniques and real-world investigations behind the evidence. So slip under the police tape, follow the trail of evidence, and see the world through the eyes of a forensic investigator. Because somewhere in the ashes… the truth is still burning.
