“Physical evidence cannot be wrong; it cannot perjure itself; it cannot be wholly absent. Only its interpretation can err. Only human failure to find it, study and understand it, can diminish its value.”
-Presiding Judge, Harris v U.S., 331 U.S. 145 (1947)
HOW TO MAINTAIN THE INTEGRITY OF THE CRIME SCENE WHILE CONDUCTING AN INVESTIGATION
First Unit Responder: A Guide to Physical Evidence Collection for Patrol Officers is a training guide and reference for patrol officers and criminal investigators, who conduct preliminary investigations of crime scenes, to aid in identification, collection, and booking of physical evidence. Written by a veteran of 24 years of law enforcement, the book stresses the importance of understanding the critical nature of physical evidence and preservation of the crime scene as part of the case against a criminal defendant. This book is an important tool for police academies that train recruits and veteran patrol officers, as well as for students of criminal justice who seek guidelines for proper collection and handling of physical evidence.
“Mark Hawthorne’s easy writing style and use of personal anecdotes make this book a relaxed read. First Unit Responder is a good resource for recruit training or criminal justice/criminology students, or as review material for seasoned investigators.”
-Cpl. Andreas K. Mendel, NCO in Charge, Forensic Identification Section, West Vancouver Police, in Canadian Society of Forensic Science Journal
