Major Decision

I need help choosing a major. I know I want to do something in the math field however specifically what I am unsure. I like to do research, forensics, crime, and math. Is there any career that combines those?

Sounds like forensic science would be a good fit. http://weusemath.org/?career=forensic-analyst
You should also look into majors in the College of Natural Science there are lots of research opportunities. Biochemistry seams to very popular as well.
