In addition, criminal investigative analyses are traditionally done on persons involved in violent and aberrant crimes. Nevertheless, computer criminals can bring financial disaster to both individuals and small businesses, and their corporate victims have characteristics like occupation and reputation that are similar to those of human victims. However, the differences between violent offenders and computer criminals present some new forensic problems to investigators. Computer criminals leave no traditional crime scene for investigators to photograph and examine, so investigators need to gather electronic trace evidence and examine logs of computer usage. Investigators should also review research on offenders and computer hackers. In addition, they should consider the criminogenic environments that Bloombecker has identified and the research indicating that the occupations most often involved in computer crimes are those with computer access.
