Forensic Ballistics

CV

I am a member of Digital Imaging Working Group of European Network of Forensic Science Institutes (ENFSI) and a member of Forensic SEM discussion group on Internet moderated by Dr. Dennis Ward from FBI’s Academy in Quantico, Virginia, where I have daily contacts with forensic scientists all over the World dealing with forensic application of Scanning Electron Microscope or Digital Imaging. 

On subject of Gunshot Residue Detection on hands and clothing I wrote a lot of publications like "Forensic Application of an ESEM" article for (I.A.M.A.) newsletter dedicated to Forensic Scientist in the detection of primer gunshot residue by SEM/EDX.

During my 28 years of practice as a Ballistic Expert Witness I realized it is hard to give a verbal explanation during Courtroom session regarding position and posture of a suspect and a victim in a moment a bullet hit the victim. Visual tools seem to be much more appropriate to illustrate possible scenarios of the particular shooting incident. Since 1996. I developed my own technique called Forensic 3D Reconstruction aiming to show possible shooting scenarios in order to be able to conclude what might had happened on scene of crime.

The first Forensic 3D Reconstruction in Croatia had been done in 1995. During the period from 2007. to 2010. there have been significant development  in Forensic 3D Technology (F3D) in Croatia. In the same period F3D was adopted in Courts in Croatia and was applied in courtrooms in practically all major crime cases in Croatia. In my opinion, those crime cases could not have been resolved without the application of F3D. Development of F3D on one side manifested in multiple development of more groups and subgroups of F3D and on the other side it was evident that F3D was not only a visualisation technique, it became an analitical forensic 3D technology characterized by the use of high resolution laser 3D scanners, software for postprocessing raw data from scanning and using photogrammetry techniques and methods. All this made it possible, for the first time, to detect and correct mistakes done by investigators and forensic experts on crime scene years after they had finished their survey. According to authorities in ENFSI Digital Imaging Working Group like Dr. Jurrien Bijhold and Dr. Zeno Gerards I am one of leading European experts in the field of Forensic 3D Reconstructions. In 2003. as an invited speaker I gave a presentation on the subject on conference of ENFSI Forensic Institutes Directors in Tallinn, Estonia.

In 2007., invited by Dr. Zeno Geradts from Netherlands Forensic Institute, editor for Engineering Sciences, Multimedia and Digital Evience section, I wrote a chapter on 3D Reconstruction (Visualisation) for Wiley Encyclopedia of Forensic Science.

During the period from 2007. to 2010., as a consequence of collaboration with Zlatan Novak, geodetic expert and expert for aqisition of spatial data, Forensic 3D Reconstruction technology had significant development and become not only visualisation but also forensic analytical technique. Merging of Forensic 3D Reconstruction with laser 3D scanning technology led to a new combination with strong visualisation and analytical potential. While the technology of laser 3D scanning allows registration of crime scenes and all phisical evidence in unprecedented quality and speed, Forensic 3D Reconstruction tecnology allows us to combine all the evidence that physically exists with the imagined simulations that intend to show what might have happened. Forensic 3D Reconstruction have been applied to more than 120 court crime cases, mostly homicides and robberies but also fire and arson cases, as well as other field of application as preservation and archeology.

In 2010. on meeting of ENFSI Digital Imaging Working Group in Trieste I gave presentation entitled Application of Laser 3D Scanners for Forensic 3D Reconstruction of Crime Scenes from Old Police Photographs and together with Zlatan Novak a workshop on application of laser 3D scanner and Visual Sensor Fusion-Suspect Measurement software on estimating a suspect's height from surveillance camera video.
