Dr. Ken Lang began his law enforcement career in 1989 with the Havre de Grace Police Department. He served as a patrol officer for two years until he became employed by the Baltimore County Police Department (BCoPD), where he served for the next 23 years. Initially assigned to the Patrol Division, the administration transferred him to the Criminal Investigation Division (CID), Crimes Against Persons Section, where he completed hundreds of violent crime investigations, including crimes of rape, armed robbery, and murder. In addition to his primary detective assignment, Dr. Lang also served as a certified Maryland Police and Correctional Training Commission adjunct police instructor at the BCoPD Academy for 16-years and as an FBI trained forensic artist, completing over 100 composite sketches for the BCoPD and other jurisdictions. His forensic art training encompassed concepts concerning composite sketches, postmortem drawings, age enhancements, two-dimensional, and three-dimensional skull reconstructions. Dr. Lang transitioned into higher education in 2014 following his retirement from law enforcement. He has served as a assistant professor at the University of Valley Forge, associate tenured professor at Glenville University, and currently serves as an associate professor for the newly developed criminology/criminal justice program at Milligan University.  When he's not teaching, Dr. Lang conducts research in the areas of police composites/sketches and restorative justice concepts, and he works as an expert witness in cases involving police practices and procedures, criminal investigations, and police composites/sketches.
