How have investigations of explosions helped in historic CSI cases?

Richard Saferstein (Former Chief Forensic Scientist) gives expert video advice on: How is evidence of an explosion collected in CSI?; How is an explosive identified in CSI?; What is a 'taggant' and how would it help in CSI? and more...

One of the most important aspects of such an investigation is identifying the components of the detonator. Clocks and watches and things of that nature will perhaps help pinpoint the origin of the maker of that explosive. A good example of collecting physical evidence at the scene of an explosion, that ultimately can lead to the identification of the explosive maker, was the Oklahoma City bombing carried out by Timothy McVeigh. At that bombing scene, investigators were able to locate the name of the truck that he used to load the explosives on. It was a Renault truck. They were also, as the investigation proceeded, able to find his fingerprints on a receipt for one of the components of the explosive. That's an important and interesting example of how physical evidence from a variety of sources can be used to pinpoint the identity of an individual who has caused an explosion.
