Aimed at the busy professional who aspires to become certified in the field, Criminal Investigation for the Professional Investigator is a single source guide that details essential techniques a trained investigator will be called upon to perform during the course of a career. Comprehensive and accessible, the book is authored by a veteran of the NYPD who gained extensive training and experience and went on to launch and operate two successful private investigation agencies.

The book covers crucial topics such as crime scenes, how to document and secure them upon arrival, how to interact with witnesses and suspects, and how to correctly obtain search warrants; death investigations…how to conduct them when they involve natural causes, suicide, homicide, accidents, and gunshot and stab wounds; the art of interrogation…warrants, techniques, and how to interrogate juveniles; and specific criminal investigations…robbery, burglary, narcotics, and sex crimes. The book also provides important strategies for making arrests and testifying in courtrooms, details the most effective investigative tools to use, and explains the role of criminal defense investigators.

Criminal Investigation for the Professional Investigator is part of the Professional Investigators series that is intended to provide all present and future members of the investigative community with the knowledge and insight to reach the height of their profession.

Author Warren J. Sonne wrote an article entitled "The Ashley Gang: What Really Happened" in the Fort Pierce-based Indian River Magazine. This article sheds new light on the exploits of one of Florida's most notorious crime families and their shooting deaths on the Sebastian Bridge in 1924. The magazine subsequently won the Best In-Depth Reporting Award for this story during the annual Florida Magazine Association meeting in Orlando.
