I'm considering changing careers to be a forensics investigator where should i start?

i'm 27 yrs old and currently work as a nursing assistant at a hospital the day to day job of nursing is starting to take a toll on me and that has me thinking of changing majors. I've always been fascinated by the police work and seeing dead people doesn't bother me since I see that already almost every day. so I wanna change majors to become a forensics investigator I know a few community colleges in my area that offers degree in criminal justice so my question is would that be a good place to start with an AA in criminal justice and can I become a forensics investigator that way? obviously I would go on to get a BA after that please any info would be great. How does the job outlook seem like as a forensics investigator in MA and how much would I be earning as salary? thanks so much.
