My general advice is to check out the Secret Service. Even consider joining an electronic crimes task force. Chicago has a good one if you are in the area, headed by the Secret Squirrels.

Make sure you get your B.S. degree and maybe go for your masters. Be a specialist in forensics, but don't forget "generalist" skills are critical (IT, business, law, etc). The Feds value solid certs like CISSP, CCNA, MCSE, etc.

Keep your record clean (no MIP, being in college  ). Surprisingly the FBI and SS often recruit young people with degrees and skills because they can "mold" them and progress them through the agency. People coming from private industry often have a lot of baggage.

I completely agree with ElCapitan, go for Fed employment.   Secret Service is one option, FBI, Customs, IRS, etc, are others.  A word of caution, you almost never get to be a forensics investigator from the start.   You have to go to Quantico first.   You then become a regular agent, eventually graduating to an investigator.   You can then request to be transferred into a forensics squad.  You will always remain an agent.  In case something major happens, you will be recalled.   You DO want to be an agent.  Agents get higher salary, better benefits, and first chance at juice assignments.   From what I have been told by ex-feds, agents look down on civilian employees.

Certifications are important.   For Federal Agents, the premier cert is CFCE, but it's only available to law enforcement.   For private sector, the cert of choice is CCE.   Interestingly enough, A+ certification still applies and is valued.   EnCE certification is also good.

I also agree that a BS degree is important.   Criminal justice, Information Security, Accounting degrees are highly sought after. 

If you live in a wealthy area, local police force may be an option.  Again, you are a cop first, then you become an investigator. 

Sounds like you are on the right track.  Stay in school and finish your BS degree.   Figure out what kind of investigation you want to concentrate on.  If you like accounting, IRS is good agency.  If you prefer criminal, FBI and Secret Service are great agencies.   Once you pass basic training, it's not unreasonable for you to be making six figures within 5 to 7 years, depending on your level ambition.   After that, the paygrades level out.   At this point, some Feds leave and enter the private sector.  There are few large forensics shops that snatch up Feds quickly.   They are great for gaining consulting experience, but they do not typically pay well.   Boutique shops pay better.   You have to do your research to make sure the shop is stable.  Beware of non-competes.

Anyway, those are my two cents.  I am probably rambling too much.  Who knows, maybe by the time you are done with school, EnCase 10.0 will have a single button, "Solve Case."  The main point is that you have to become an investigator.  Technical skills can be taught, by investigative skills are much more difficult to acquire.
