I want to be a homicide investigator, what should i major in college?

You should not pick your life profession based on the subconcious liking of a TV show.... also, after college, I regret not looking into the ENTIRE PROFESSION I wanted to pursue (including the boring, and hard parts of the job I was looking at) So I recommend you truly look into doing free work (intern) at a job you'd like to do. Ask the people if they would take a week internship, or if you can follow a person for a day to help them and learn the field. Also, DO NOT GO TO THOSE TV COLLEGES! You are seeing them all day now on TV, and over 90% of those colleges spam on TV are scam, for-profit colleges that will not find you a job after you graduate and the "degree" faked as a useless paper will serve you no good to most employers. They all are scam companies and liars for the most part. GO TO A REAL COLLEGE, or a community college if you are tight on cash. BELIEVE ME, THIS IS THE FIRST STEP!
