Background: In the current scenario, glass plays a vital contribution in our standard everyday life. Fractured and fragmented glasses are most commonly encountered at the crime scene. During the commission of the crime, glass breaks and shatters into fragments or into minute particles that serve as trace evidence and may provide a significant lead for the probe. The fracture of glass could be the consequence of an intentional act or unintentional act. For the forensic purpose, study of glass fractures, i.e., fractography has paramount importance as it can provide noteworthy data and encourages an assortment of assessments to investigate the case especially in the shooting cases where a firearm is used. Multiple fractures on a glass pane also have enough potential to establish an investigative link. Presently, air guns are being used in many of the cases due to their simple accessibility. There are a number of cases that have been reported that involved the use of air guns. Result: This study was conducted to evaluate the pattern of multiple fractures on the glass by the air rifle. For this purpose, glass panes of various thicknesses were test fired perpendicularly at a fixed range with an air rifle having round nose pellet. Measurements and analysis were made on some fixed parameter. Data was analyzed graphically and statistically to check the consistency in the trends. Conclusion: Consistency in the trends was observed, which is analyzed by the test for the goodness of fit. The findings of this work have provided some significant different perspectives that may effectively contribute to the criminal investigation.

Now a days crimes relating to firearms and ammunition have dramatically increased in northern part of India. It has been observed that Country made pistols of 8mm/.315" bore; Improvised pistols of 7.65mm/9mm calibre, .32"/.38" calibre are randomly used by criminals in Delhi and NCR regions. On the basis of crime cases received in the Forensic Science Laboratory for examination, the smooth bore illegal country made firearms chambered for pistol, revolver and rifle cartridges are very often encountered in criminal cases all over India and other developing countries. The possibility of identifying types of smooth bore firearms of country made and improvised pistols has been studied. On analysis of crime cases received for forensic examination, it has been found that 75% crimes are committing by 8mm/.315" calibre by country made pistols, 20% by 7.65mm calibre/bore improvised pistols and remaining 5% crime by other firearms like 12 bore country made pistol, .32"/.38" calibre/bore improvised pistols. In present study, firearms details relating to length of barrel, total length of firearms, internal diameter of barrel at muzzle end and breech end have been studied in view of forensic significance and may be useful for Forensic scientists, Law Enforcement Agencies, Police Officers and Judicial Officers etc.
