Words from Colleagues

Pete Gagliardi

Crime Gun Intelligence

Consultant (Retired ATF SAC and FTI SVP)

"I met Paul Murphy in 2005 when I was looking to hire a firearm examiner to assist our scientists and engineers at Forensic Technology Inc. (FTI) with developing the next generation of IBIS™ Technology. Before his time in Virginia, Paul had spent over 20 years as a law enforcement officer in South Africa, where he was a Senior Superintendent and Commander of the Eastern Cape Provincial Forensic Ballistic Laboratory. Moreover, with his seven years of working forensic firearm cases for the State of Virginia, Paul had all the qualifications we sought.


What distinguished him was his ability to work independently and in collaboration with others, his relentless work ethic, his ingenuity, and a level of resourcefulness that convinced me that he could rise to meet and beat any challenge. We hired him, and IBIS™ and FTI were all the better for it."

Piet R. Gouws

South African Police Service (Retired Brigadier, Section Head of Ballistics Section: Forensic Science Laboratory)

"I have had the privilege of knowing Paul J. Murphy since 1984, when he began his career as a trainee Firearm and Toolmark Examiner with the South African Police Service. From the outset, Paul proved to be a top performer, demonstrating exceptional professionalism, leadership, and strong interpersonal skills.


Throughout his career, Paul consistently delivered outstanding results, playing a critical role in high-profile firearm investigations. His thoroughness, integrity, and in-depth expertise earned him immense respect from colleagues and the judiciary alike. Notably, Paul was instrumental in decentralizing South Africa’s Ballistics investigation services, successfully establishing a new laboratory in the Eastern Cape. Promoted to the rank of Colonel in 1996, Paul’s leadership and technical skills are unparalleled. Since relocating to the USA, he has continued to excel internationally and is, without a doubt, one of the most experienced specialists in Firearm and Toolmark examinations."

Johann Claassens

American Society of Crime Lab Directors (ASCLD)

"I have known Paul Murphy for decades, working closely with him during my time as Director of the Chemistry & Applied Sciences Unit at the South African Police Service’s Forensic Science Laboratory.

Paul’s expertise in forensic ballistics has been pivotal in solving countless cases, analyzing firearms, ammunition, and ballistic evidence with precision.


His skill in reconstructing crime scenes, linking evidence to firearms, and presenting findings in court has been instrumental in achieving justice.

Beyond his casework, Paul is a dedicated researcher whose work bridges theory and practice, advancing forensic science in areas like ballistics and firearm mechanisms.

What truly sets Paul apart is his attention to detail and ability to explain complex findings with clarity, earning widespread respect in law enforcement and the legal field.

I confidently endorse Paul Murphy as a trusted leader in forensic ballistics and a champion of justice."


James E. Hamby, Ph.D.

Lab Director, International Forensic Laboratory

"I am writing this brief testimonial to highly recommend Paul Murphy as a firearm and tool mark examiner. I have known Paul for over 25 years and have witnessed his numerous abilities and skills in our field. Paul was instrumental in assisting me with an international research project where he provided numerous double-cast clone sets of bullets from 10 consecutively rifled barrels. These sets have been used by examiners in some 34 countries for research and training.

 

At numerous AFTE Training Seminars (Association of Firearm and Tool Mark Examiners), we have had the opportunity to exchange information. It is obvious that Paul is a well trained and skilled examiner and capable of providing thorough and complete analysis and examination of firearms and tool marks related evidence. Additionally, as a former forensic laboratory director, he has a firm grasp of the  overall forensic science capabilities."

Alain Beauchamp, Ph.D. 

Director, Research and Prototypes - LeadsOnline

"For nearly 20 years, Paul has contributed to the development of automated firearms identification at LeadsOnline, working closely with scientists and developers, sharing his expertise, suggesting solutions to specific problems and providing relevant physical samples. As the company's subject matter expert, he has also given numerous training courses around the world on firearms and on a double casting technique he personally perfected. He also keeps up to date by attending relevant symposia and trade shows every year. I warmly recommend Paul to anyone needing expertise in firearms and firearms identification."

lehi sudy dos santos, ph.D.

Administrator of the National Ballistics Analysis System - Federal Police of Brazil

"I met Paul Murphy in 2022 when he came to Brazil to present a talk and to teach in a Workshop at the National Forensic Conference. His teachings and experience as a Firearm Examiner were instrumental for training Brazil forensic practitioners that were at the time starting to use Ballistic Identification System in a National Network.

 

Since then, I have learned from him in multiple conferences, workshops, and meetings. He is internationally recognized as a skilled and talented firearm examiner well prepared to conduct exams in real case evidence, carry out research projects or to deliver training with great expertise.
I also had the privilege to join him visiting ammunition and firearm manufacture facilities, where his comprehensive knowledge, inquisitive mind, and passion for this field of knowledge were inspirational for me.

 

Not only because of his exceptional professionalism, but also considering his integrity, honesty, and strong interpersonal skills I do not hesitate in endorsing him for specialized consulting and examination, case review or training programs."
