forensic man

Hello everyone. my name is Zach and i'm new to the site. My career goal has been to become a pharmacist, but I am starting to think that that job is a little boring. My wife is an RN in the ER and she has been trying to convince me to become a nurse. I got my CNA in high school and never worked in the field after i got it. I have been reluctant until i started learning about forensic nursing. I know it is only a tv show, but i really enjoy CSI and was looking into becoming a crime scene investigator. however in my city, there is no demand for them. our police dept only has 2 investigators. So my wife mentioned forensic nursing, and it kinda caught my eye. Could anyone give me some specifics about the job. I have seen on all these websites that you collect evidence, testify in court, could anyone give me scenario of a day in the life of a forensic nurse? Is it in any way like they show on tv? Any info is greatly appreciated. Thanks
