FBI Investigates - The Investigation

Photograph of an explosive devise.The box and the flashlight were sent to the FBI Laboratory's Explosives Unit; two examiners were assigned. One examiner determined that the box contained an explosive; the other examiner determined that the flashlight had been modified into an explosives device. How did they do that?

The Case Agent soon learned that the flashlight and the wooden box were not the only important clues. In the bushes near the door, investigators found a backpack with papers inside. Ultimately, the investigation and eyewitness accounts led the Agent to a suspect. The Agent requested and executed a search warrant for standard samples of the suspect's blood, handwriting, hair, and paint from his motorcycle.
