The late Karen Matison Hess, PhD, wrote extensively in law enforcement and criminal justice, gaining a respected reputation for the consistent pedagogical style around which she structured each textbook. She co-authored multiple editions of MANAGEMENT AND SUPERVISION IN LAW ENFORCEMENT, CRIMINAL INVESTIGATION, JUVENILE JUSTICE, and INTRODUCTION TO LAW ENFORCEMENT AND CRIMINAL JUSTICE in addition to CONSTITUTIONAL LAW AND THE CRIMINAL JUSTICE SYSTEM; much of her work and influence remains unchanged in this new edition.
