In my experience it is "Forensic anthropologists" and not "Forensic archaeologists" that are hired to work on those types of projects.

The times I have been hired to work on a forensic case, it was because a Forensic anthropologist hired me and I was typically the only archaeologist on the project. All the others focused in some type of biological anthropology. I was honestly only hired because I knew the Forensic anthropologist and they knew I was interested in helping.

Each time, it was a contract position where the local law enforcement hired a university professor. There are very few places that have full time forensic anthropologists and there may be 1 per state. It is much cheaper to law enforcement to just do contract hires on the rare occasion that they are needed.

Here's my advice. This summer sign up for the Culver Archaeological Project in Lewes. You'll learn a lot about archeology, makes some friends who are archeologists and the professional staff will know everything there is to know about a future job in archeology. Also, you're going to find some great Roman stuff buried in a corn field.
