ABSTRACT
Once the investigation has begun, the investigator should attempt to nd and identify all evidence that may be associated with the case. Even items that may seem unimportant and of no value should be considered potential evidence. In murder investigations, there is usually an abundance of evidence even in cases in which the suspect has attempted to clean up aŸer the crime. Even in a so-called perfect murder, there will be much evidence to aid in the crime’s solution. In fact, there is no perfect murder-only cases in which a deliberate killing could not be successfully prosecuted beyond a reasonable doubt.
