​A Student's Experience:
​
“Thank you for the opportunity to attend this class!  This was an extremely informative class, and I found it very hard (which is a good thing) because of my lack of experience in major crimes. So this gave me the chance to see what crime scene reconstruction is all about and how you even begin to put things together at more involved scenes. Because of this class, I will now know what to look for when I do work a major crime scene”.

Tina Stidham, Crime Scene Investigator, Boynton Beach Police Department, FL
