Perhaps you could contact them about internships if their location allows that. Sometimes if they are really impressed and have a vacancy they offer you a job or otherwise try to connect you to positions. It happened to a few of our students. One got a one year paid internship with the GBI two semester before her graduation and is doing her last class or two online or as a transient student.
Secondly, if you attend a forensic science conference, especially AAFS you can actually speak to agency personnel directly.
