  Great question!
  Many crime scenes are examined in less than an hour, but the longest i have been involved in has taken months to examine!

  I mainly worked at a lab comparing fingerprints.
  
  It is Crime Scene Investigators (CSIs) that regularly attend scenes. They can spend days and even weeks at complex scenes involving very serious crimes.
  
  I attended scenes mainly to offer advice on the collection of fingerprints, and the longest I spent at a scene was 2 days for a murder.
  
  My role was fairly easy. The body had already been sent to the mortuary and lots of the hard work had already been done.
  
  But it was a very responsible job, as there is always a chance that I could miss something or give advice that could negatively impact the investigation.
