The investigator lacks forensic expertise, the crime scene technicians lacks investigative skills; typically much later a crime lab examiner removes evidence from a property room with minimal knowledge, if any, of the details or alleged version of events.
Tangible and intangible evidence which should have been present at the scene is not considered; critical evidence gets overlooked or fails to be collected or documented.
Result: the investigator, crime scene, and forensics fail to work in unison resulting in a flawed investigation abundant with omissions which can be intentional or unintentional.
Attorneys/prosecutors do not realize the discrepancies which exist and are at a disadvantage in presenting their case.

I am privileged to be one of a handful of persons with combined experience in both forensic and criminal investigations with hands-on involvement in literally thousands of shooting incidents from septuple homicides to defective design of firearms including catastrophic failures.

Currently I am one of 24 forensic experts selected nationwide to be a member of the American Academy of Forensic Sciences Consensus Board on Firearms and Toolmarks which is responsible for developing the standards and methodologies to be employed in these areas as required by the Congressional Act which mandates the overhaul of all forensic science disciplines.

Sub-specialize in police shootings and have investigated over 400 officer involved shooting incidents. I was a member of the State Police Firearms Review Board, have conducted internal department shooting investigations.

I have been the Commanding Officer of the MSP Firearms Section, the Troop Shift Commander of 6 barracks, a Staff Inspector, Commander of an urban Boston area State Police Barracks, and Shift Commander of the state-wide Operations Section, and commanded the shift operations of multiple barracks at the troop level.

Military service in the Army Ordnance Corps testing and researching; total experience is almost 55 years in firearms & ballistics; and over 35 years in forensic areas; I have testified approximately 350 times at all levels of the civilian and military courts.

Qualifications Statement Addendum to CV

I am a 25-year plus retired Commissioned Officer of the Massachusetts State Police with over half my career in the MSP Ballistics Section and was the Commanding Officer of the main and sub-labs with 7 forensic examiners; I conducted, supervised, and trained personnel in forensic investigations, shooting reconstruction, and the dynamics involved in shooting incidences. I have also conducted criminal investigations related to shooting incidences and other crimes.

The firearms lab provided crime scene investigation and forensic examination services to 350 cities and towns, all State agencies, Federal agencies except the FBI, and the military services in Massachusetts. I was an appointed member of the MSP Firearms Review Board which evaluated departmental officer involved shooting incidences and made recommendations for discipline, training, and/or changes and improvements to Department Policy and Procedure and Department Rules & Regulations.

As a member of the Staff Inspections Unit, I conducted agency shooting investigations, claims of excessive force and/or police misconduct, and violations of Policy & Procedure and Rules & Regulations. During 1987-88 I conducted evaluation testing of multiple models and makes for semi- automatic firearms using methodology similar to that employed by the military weapons testing.

I have investigated over 400 police involved shootings including incidents of fatal and nonfatal shootings, friendly fire injuries and deaths, involuntary or unintentional discharges, appropriate and inappropriate use of deadly force with firearms, less-than-lethal and non-lethal ammunition shootings, conducted electrical weapons, firearms of single shot, semi-automatic, and full automatic design; this includes revolvers, pistols, rifles, machine guns, grenade launchers, shotguns.

I have personally conducted thousands of forensic investigations, including crime scenes, attended approximately 700 post-mortems, and was trained in the forensic interpretation of gunshot wounds from a shooting reconstruction perspective (particularly, with respect to the relative positions of the shooter or firearm and the victim) by Chief Medical Examiner of Suffolk County, Dr. George Katsas and Dr. Albert Shub of Essex County. I have also attended numerous gunshot wound presentations and read the treatises on gunshot wound evidence authored by prominent forensic pathologists.

In addition, I have trained with or studied treatises published by other prominent forensic pathologists since 1979 in gunshot wounds and terminal ballistics. I have personally observed fatal and non-fatal gunshot wounds as they have occurred in my presence. I have attended the Bureau of Alcohol, Tobacco, Firearms National Firearms Academy Investigation course, FBI courses, state law enforcement courses, medico-legal death seminars, thousands of hours of in-service training at the State Police Academy, numerous crime scene shooting reconstruction courses, forensic seminars, etc.

In the aggregate, I estimate having been personally involved in about 5000 shooting investigation cases dating back to 1973. Of that total approximately 1000 were fatal shootings with the remainder consisting of non-fatal, property damage, bank and armored car robberies, domestic violence, malicious destruction, inadvertent and unintentional discharges, hunting and firing range incidents, self-inflicted wounds, drive-by shootings, self-defense, negligent and unsafe firearms safety discharges, military and combat injuries from gunshots, organized crime, terrorist activities, friendly fire, spontaneous disassembly and catastrophic firearms and ammunition failures, homemade and prison made firearms and silencers, international assassination attempts resulting in gunshot injury, shooting incidents in international waters and other types of shooting investigations and reconstruction.

During my experience and training I have utilized and analyzed several hundred video and audio recordings of shooting incidents to reach scientific conclusions, including the existence and use of a firearm, the rate of fire, muzzle flash, type of firearm in the video, time, speed, and motion over distance using slow-motion and frame-by-frame sequencing. These video and audio recordings have included private monitoring systems, surveillance systems, police observation units, police in-car dash camera video, on-body camera and audio devices, Go-Pro camera digital video, civilian recordings on cell phones and digital cameras, and video and/or audio recording evidence provided by the news media or other sources.

As an expert witness I have testified over 350 times in all areas of firearms, ballistics, shooting reconstruction, and shooting dynamics at all levels of the court system including Federal Court and Military Hearings. Testimony also has been given before the Massachusetts Legislature and consultation provided to Massachusetts Congressmen to assist with legislative issues.

My U.S. Army active duty career was within the Ordnance Corps and included extensive training and assignment in the testing, evaluation, repair and research of small arms and training in Explosive Ordnance Reconnaissance. I attended the U.S. Army Ordnance School at Ft. Dix and Small Arms Repair School, at Aberdeen Proving Ground, MD and spent most of my military career researching and testing Eastern Bloc weapons systems during the mid-1960’s while assigned to an Ordnance Company in Germany where I was the Company Armorer and Crew Chief of the Headquarters Weapons Platoon responsible for the training and operating of .45 Auto Model 1911 Pistols, M14 Rifles, M14A1 Full Automatic Rifles, Browning M2 HB crew served machine gun, M79 Grenade Launcher, AR-15 Assault Rifles, M16 Full Auto Assault Machine Rifles, M72 LAW Rocket, M20 Super Bazooka, and various types of explosive ordnance (grenades, claymore mines,etc).

I was qualified to perform the highest level of repairs to the M2 and most small arms and machine guns. I was qualified as both a “Direct Support” level technician and a “General Support Level” technician and armorer. At the unit level I was the Armorer for the 40th Ordnance Company located at Neureut Kaserne in Karlsruhe, Germany.

I have trained with the MSP Special Tactical Operations (STOP) team, been involved in shooting incident reconstruction from airborne platforms including police and military helicopters, and with the 10th Special Forces Group at Fort Devens, MA for special weapons and tactics.

My weapons proficiency includes significant professional competition championships including World International Handgun Metallic Silhouette Championship 1980 winner, being the first Massachusetts State Police Officer to fire a perfect combat course score with a revolver; I hold a proficiency rating of Master Shooter and was a firearms instructor for several decades, and have had both a Federal and State Firearms License for full automatic firearms; I am currently a Federally Licensed Firearms Dealer and have taught Firearms and Hunter Safety Courses.

In 2002 I became an independent forensic consultant and provide services including firearms, ballistics, shooting reconstruction, ballistic testing, gyroscopic stability; internal, external, and terminal ballistics; reaction time, analysis of time and motion in a shooting incident, trajectory and drag model analysis and other specialized services. I have been retained by the U.S. Military, engineers, insurance companies, attorneys, prosecutors, authors, architects, Innocence Projects, and conducted work for both plaintiffs and defendants in civil litigation matters.

Since 2002 I have been involved in over 600 investigations requiring shooting reconstruction and/or forensic investigation in every state, and in Haiti, Virgin Islands, United Kingdom, Israel, Afghanistan, Iraq, Canada, Nigeria, the Philippines, Colombia, and Pakistan.

My forensic training, education, and experience are over 35 years, and my overall experience with firearms, ballistics, etc., exceeds 57 years. I have testified on numerous occasions regarding discharged cartridge case ejection and received advanced training and have personally conducted hundreds of generally accepted tests for determining discharged cartridge case ejection patterns, including actual testing of semi-automatic pistols, full automatic pistols, and machine guns and submachine guns, as well as studied literature on ejection pattern testing protocols published in the Journal of the Association of Firearms and Tool Mark Examiners, the Journal of Forensic Science published by the American Academy of Forensic Sciences, the FBI Bulletin, during factory Armorer Courses, Investigative Science Journal, and numerous books on shooting reconstruction including those by Dr. Vincent J. M. DiMaio, Edward Hueske and Lucien Haag, the Indiana Professional Engineer Magazine, blood splatter analysis, gunshot distance, wound ballistics, angles of gunshot impact, and the elements of time, motion, and distance in shooting incidents including reaction time for various shooting motions, rate of fire, holster retention levels, gunshots occurring during struggle over a firearm, and other issues.

I voluntarily submit to proficiency testing with the Collaborative Testing Service and I am one of approximately 20 voting members of the American Academy of Sciences Academy Standards Board (ASB) which is developing Best Practices, Technical Reports, and the national standards required by the Congressional Forensic Science Act in the area of firearms and tool mark examinations through the Consensus Board for Firearms and Tool Marks.

I have given peer-reviewed scientific forensic presentations at numerous colleges and universities, seminars for District Attorneys and private attorneys, emergency medical service responders, police academies, private investigator meetings, and at annual meetings of several professional organizations of which I am a member or former member.
