Firing Pin Impression Depth & Volume Measurements

Jason Butell

Objectives:

• -Historical use of FPI depth measurements

• -Attain reliable measurements of FPIs

• -Remain ASCLD/LAB & ISO Accredited compatible

• -Utilize measuring device that is economically available

• -Compare FPIs from various types of firearms in both double & single action
• -Glean FPI depth & volume in metric & US Customary units
• -Importance of these measurements Methodology: By following the Scientific Method and utilizing the Keyence VHX-600 digital microscope to measure FPI depth and volume. Both a revolver and semi-automatic pistol are used for the experiment, and both discharged in single and double action. These measurements are tabulated for comparison and examination of possible errors, differences and to test if hypothesis is true or false.
Results: On a small scale the test indicates that there are differences in the depth and volume of FPIs in both the revolver and semi-automatic pistol regarding whether single action or double action was used.
Conclusions: The advent of newer technology brings to light finer details that were once not as attainable or feasible. This also allows for further documentation of once excluded information, while maintaining laboratory standards. However, this will be an ongoing experiment in an attempt to gather as much information as possible.

Physical Matching as Duties of a Firearms and Toolmark Examiner
Jaco Swanepoel
Objectives: To establish through physical matching and microscopical comparison if the hydraulic pump and the base plate which it was mounted on were in contact with each other.
Methodology: Side by side and microscopical comparison of the specific areas of contact between the hydraulic pump and the base plate, several different Microsil and forensic sil casts were made to assist and facilitate the various photographic and microscopical comparisons. A strong light source at various angles of incident also enhanced certain class and individual characteristics.
Results: Through comparison sufficient class and individual characteristics were identified to make a conclusion possible.
Conclusions: The base plate and the hydraulic pump were joined to each other for a sufficient amount of time to ensure the mutual carry over of sufficient class and individual markings / characteristics.

Wound Ballistics 2008 ‘Looking Forward Looking Back’
David Andrew
Objectives: Wound Ballistics is a science driven by need. The current conflicts in the Middle East have given a new impetus. 'Mythbusters' and the gratuitous use of ballistic gelatin have also helped. This paper looks at what we have learned and how it could be used in the future.
Methodology: A literature and media review was undertaken. This was then analyzed and evaluated.
Results: Old lessons are being relearned, and a lot of information is again resurfacing on energy transfer. Bullets are getting bigger, and blast injury is becoming the focal point.
Conclusions: A new definition of Wound Ballistics, "A Study of Bombs, Bullets and Blast upon the Body". The design of Body Armour is being evaluated under these principles, bullets are getting bigger, and blast is a major focus area.
Biography: David Andrew is a Registered Nurse at Berri Hospital in South Australia, and a Lieutenant in the Australian Army Reserve. He holds a Masters of Nursing Degree and has served in the Australian Defense force in various roles for over 32 years. He has presented in this field for over 20 years and presented at AFTE in 2006.

Visualization of Gunshot Residue Patterns on Dark Clothing Using a Video Spectral Comparator
John Durina and Marie Durina (and others)
Objectives: The determination of muzzle-to-target distance is often a critical factor in criminal and civil investigations involving firearms; however, seeing and recording gunshot residue patterns can be difficult if the victim’s clothing is dark and/or bloody. The Video Spectral Comparator (VSC) is an imaging instrument routinely used by forensic document examiners. The VSC 2000TM model (Foster & Freeman Ltd, Evesham, Worcestershire, UK), includes a color charge coupled device (CCD) video camera, a black and white CCD video camera, various radiant energy sources, and numerous excitation/barrier filters.
This research set out to determine if the VSC could quickly, easily, and reliably provide instantaneous viewing, saving, and printing of gunshot residue patterns on dark and bloodstained clothing without the use of specialized film, and without chemical processing.
The study examines the reliability, speed, and accuracy of determining muzzle-to-target firing distance from gunshot residue particle patterns using the Video Spectral Comparator 2000 (VSC) 2000. Examinations included (a) the use of the VSC 2000 to detect gunshot residue particles on dark clothing, and; (b) what effect the addition of blood to the materials may have in making firing distance determinations using the VSC 2000.
Methodology: Five different types of dark clothing using eight different handguns of different calibers were examined. Test fires were made on dark colored fabrics at three muzzle-to-target distances of 6 inches, 12 inches, and 18 inches Test fires into white, unstained, cotton fabrics at 6 inches were used as controls. The target fabrics were then viewed with a Video Spectral Comparator. After results were obtained, some of the fabrics were then stained with human blood from crime lab stock supplies. The target fabrics were then viewed again with the Video Spectral Comparator. Images of results were recorded.
Results: Gunshot residues were readily detected, and patterns were easily seen on dark clothing. Bloodstains did not preclude the viewing of these patterns.
Conclusions: This study has determined that the Video Spectral Comparator (VSC) can assist firearms examiners in quickly and easily visualizing gunshot residue patterns without any specialized film, or chemicals, and with instantaneous viewing, saving, and printing of the image. Video Spectral Comparators already exist in many crime labs and are used frequently by forensic document examiners. The VSC is also a useful tool for examining gunshot residue patterns and determining muzzle-to-target firing distances. Biography: Christina Atwater graduated from National University, San Diego, CA in 2005 with a master’s degree in forensic science. Marie Durina is a Forensic Document Examiner with the San Diego Sheriff’s Crime Laboratory Questioned Document Unit, San Diego, CA. John Durina is a Criminalist in the Firearms Unit of the San Diego Police Department Laboratory, San Diego, CA. Robert D. Blackledge is a retired Senior Chemist, formerly with the Naval Criminal Investigative Service Regional Forensic Laboratory, San Diego, CA, and an adjunct professor of Criminalistics with National University, San Diego, CA.

The Antwerp Massacre and the Consequences for a Small Country
Dr. Jan De Ceuster
Objectives: In 2006, a young guy created a massacre in the Old Town of Antwerp, killing two persons and severely wounding a third one. These murders had tremendous influence on the whole of the country; the people were in shock. It was the first trail in Belgium where the accused was eventually convicted for murder with racist motives. Also, in the aftermath of these murders, the Belgian firearms legislation was rapidly changed by the government.
Methodology: The audience will be given an overview of what happened on that particular day and what happened in the days following the crime. The ballistic investigation included a study of the terminal ballistics of the .30-30 bullet. The surviving victim was shot through a mammary implant, which could have saved her life.
Results: 1. An overview of the current Belgian firearms legislation is given. Up to date this law is still not fully applicable. 2. Using ballistic soap and gelatine, the influence of a mammary implant was shown to reduce importantly the wound cavity behind. High-speed video enabled us to study the temporary cavity in ballistic gelatine, which confirmed the results of the ballistic soap.
Biography: I have a PhD in science (physics) and have been working at the NICC for 5 years as a firearm and toolmark Examiner. This is my 4th AFTE Meeting and I have been a provisional member of AFTE since 2007.

The White Light Interferometer, Will it help us meet the Daubert challenge in Firearm/ Tool Marks
Gerard Petillo Connecticut DPS Forensic Lab Firearm/Tool Mark section
The motivation for this research began while reading a 19 page affidavit in support of a defendant’s motion to exclude ballistic evidence. The expert retained by the defense who is not a practitioner in this field, who has a background in material science made many assertions to refute the scientific reliability of Tool Mark Identification. Most if not all of these assertions have been previously addressed in publications both in the AFTE journal as well as the JFS. 
A specific quote in this affidavit that is the subject of this research suggests the use of the white light interferometer as an instrument to be used in the analysis of fired ammunition components to determine origin. This statement has the potential to present problems for the uninformed examiner.
My objective for this research is to present information regarding the white light interferometer and then use the instrument to examine fired cartridge cases to see from a practical perspective what information can be gleaned from the use of this instrument as well as the value of the data to the field of Firearm / Tool Mark Identification.
Results:  For many reasons, this instrument is currently not suitable for use in casework.
Biography: Gerard Petillo is one of four examiners working in the State Forensic lab’s Firearm and Tool Mark section. He is a member of the New York Microscopical Society and a regular member of AFTE. He has served on the 2006 Training Seminar Host committee. He is currently on the Historical committee and a moderator on the AFTE Forum.
