crime scene investigation....?

I was considering this as a career myself so I did a little bit of research on it a few months back. She will need a degree in either biology or another human science, or physics, a four year degree will do. many colleges specialize in criminal justice courses. it all depends on what she likes to do and decided to major in. for example, if she wants to be an actual crime scene investigator, she's better off taking a standard four year major in a human science or physics, and then joining the police academy. crime scene investigators that have been trained as police officers are considered part of the union, receive better pay, and are able to carry firearms and make arrests and have all the same powers as regular officers. if she'd rather be a forensic scientist that works behind the scenes, she could study to become a medical examiner, trace expert, ballistics expert, along with the many other crazy fields that they have that just might interest her.

It depends on where she wants to work. Forensic science is what crime scene investigation is all about. She should call the department she wants to work for and ask them. Some police departments, the police officers are trained and work as crime scene investigators. Others are just flat out scientists and are not police officers. Criminology is a good base, and work in some forensic science if available.
