       The task of forensic investigation is perhaps akin to solving a picture puzzle. Initially, there are perhaps hundreds, or even thousands, of seemingly disjointed pieces piled in a heap. When examined individually and carefully, each piece may not provide much useful information. Methodically, the various pieces are sorted and patiently fitted together according to a logical connection. Slowly, an overall picture emerges in your mind. When a significant portion of the puzzle has been solved, it then is easier for you to see where the remaining pieces fit.
