World’s scientific journals release CDRD’s discoveries

July 29, 2021

Some of the peculiar findings of Centre for Defence Research and Development (CDRD) were appeared in the famed forensic science journals recently, the CDRD said.

The CDRD, premier defence research arm in the country, functions under purview of the State Ministry of National Security and Disaster Management, recently disclosed a series of scientific research articles comprising afresh scientific insight in the area of forensic ballistics; the firearms and ammunition related investigative sciences.

The CDRD’s Ballistics Wing released these novel scientific research articles to the world through various scientific journals.

Accordingly, the Journal of Forensic Sciences, Forensic Science International, Forensic Science International-Digital Investigations, Science and Justice etc. were among some of the scientific journals those published by the leading scientific journal publishers in the world such as Elsevier and Wiley.

This periodical publish novel finding concerning the diverse ricochet behaviour of AK bullets and has emphasized the utilization of the findings as forensic evidence in shooting incident reconstruction.

AK variant assault rifles are currently reported in crime scene shootings, locally and internationally with a cumulative trend. However, there had been a considerable knowledge gap with regard to the ricochet behaviour of AK bullets (7,62 x 39 mm).

According to the CDRD, new disclosures entailing a series of empirical test results, those scrutinized during field test firings could be used as viable forensic evidences for scene reconstruction of AK gun related investigations.

Forensic scientists and shooting investigators in the world frequently use empirical test results of the ricochet behaviour of dissimilar bullet types and ammunition for shooting incident reconstructions and also for court proceedings.

The CDRD also stated “due to the high risks involvement in conducting ricochet experiments with high velocity bullet, there had been a serious lack of data pertaining to AK bullets”.

The afresh works highlights numerous significant phenomena that hadn’t been previously reported in any scientific analysis.

Transforming their research culmination into a dramatic practical operation, the CDRD said their team has introduced maiden android based field investigation tool to estimate the exact direction of the impact of AK bullet on light vehicles, using the bullet holes.

The novel method has been validated and divulged in the “Forensic Science International– Digital Investigations” magazine by famed Elsevier publishers, the CDRD sources said.

The new tool was introduced and demonstrated for the Sri Lanka Police for their use, recently at the Panaluwa Firing Range.

The CDRD team under the directives of Lt. Col. Bandula Nishshanka, Head of Armament and Ballistics Wing, who is an eminent scholar in the field of ballistics, forensic ballistics and armaments, accomplished the much valued exploration.

The team also included Maj. WC Ariyarathna, Lalindu Weerakkody, Jayanga Palihena and Dr. Chris Shepherd of Kent University in United Kingdome, the CDRD added.
