There are lots of areas of forensics one could go into. If you are interested in the process of evidence collection, that would be a true CSI or evidence tech. Most people who do this are first trained as police officers. If you want to be the person working in the lab that examines samples, then you would need degress in pathology or biology. There are also forensic photographers who photograph crime scenes and bodies. A lot of times, they tend to be evidence techs with special photo training. There is also something called a forensic nurse examiner (that's what I am). In most states, a forensic nurse is an RN with special certifications in sexual assault examinations. I work for a county in which our forensic nurses also help with homocide cases by going to crime scenes, hospitals, jails and morgues to do full body examinations for injury documentation, photographs, and evidence collection off of bodies (either homocide, sexual assualt, abuse, or even collection from suspects. Good luck in whatever you decide to do!
