Introduction to Crime Scene Investigation on Explosion Cases
The Explosion Investigation Section is responsible for investigation of all kinds of explosion cases such as bombing incidents and explosion accidents. Explosion cases can become serious social problems due to their cruel damages on human bodies and properties. An explosion is defined as a violent, shattering action caused by a bomb. The main chemical ingredient of a bomb is the explosive – an endothermic substance that serves as a storehouse of energy. When this energy is suddenly released, in the confined space of the bomb, it causes a devastating effect, resulting in loss of lives and property. As compared to conventional crime scenes, explosion sites are more difficult to process.
