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.
