Arnold Markle was the State’s Attorney for the Judicial District of New Haven from 1968 until his untimely death in 1987. Mr. Markle, a native of New Haven, graduated from the University of Pennsylvania and the Boston University Law School after service in the United States Navy. He served as an assistant United States Attorney in New Haven before being named the first statewide chief prosecutor for Connecticut’s Circuit Court. Known for his feisty nature and his skill as a prosecutor, Attorney Markle instilled both loyalty and admiration in all with whom he worked.

Arnold Markle strongly believed that training and continuing education were important for police officers and all members of the criminal justice system. He started the arson task force for New Haven and established training programs for arson investigators. He believed in the teamwork of prosecutor and law enforcement, as reflected in his well-received handbook The Law of Arrest and Search and Seizure: A State’s Attorney’s Guide for the Prosecution or the Law Enforcement Officer.

Mr. Markle had a long association with Dr. Lee and the University of New Haven, teaching various courses including arson investigation, homicide investigation, law and evidence. He was one of the first prosecutors to understand the importance of thorough crime scene documentation, standard procedures for crime scene investigation, and the value of forensic evidence to provide investigative leads and in criminal trials.
