Planning a crime isn’t easy. There is plenty to consider. Metro Nashville Police Lieutenant Frank Ragains is an instructor at Volunteer State Community College. He designs mock crime scenes so that students can collect evidence and document the scene with a critical eye. Effective evidence processing is important in a criminal investigation. Mishandled evidence could be lost or found inadmissible in court. Vol State students now have more room, and more time, to investigate mock crime scenes thanks to a new Criminal Justice lab building at the college.
