Forensic Firearm Examinations: Select A Real Homicide Case

Forensic Firearm Examinationsselect A Real Homicide Case In Which A Fi

Forensic firearm examinations select a real homicide case in which a firearm was used to commit the crime and forensic examinations of evidence related to firearms (cartridge casings, bullets, GSR, etc.) were utilized to assist in determining “what” happened. First, summarize the case, then explain in detail the role forensic firearm examinations had in the case. What did the examinations and evidence reveal? Consider the use of GSR, ballistics, and NIBIN in the case. You can also discuss other forensic evidence, but the focus should be on firearm evidence. Your assignment should be 3 pages in length, written in APA format, and include at least two scholarly references.

The case selected for this analysis is the 2007 homicide involving the shooting of Kathryn Eastburn in Fayetteville, North Carolina. This case garnered significant forensic attention due to the utilization of firearm examination techniques, including ballistics analysis, gunshot residue (GSR) testing, and the National Integrated Ballistic Identification Network (NIBIN). The forensic investigations played a crucial role in elucidating the circumstances of the shooting, identifying the firearm used, and ultimately leading to the arrest and conviction of the perpetrator.

In the Eastburn case, Kathryn Eastburn was shot in her home, and the evidence collection included cartridge casings, bullets recovered from the scene, and GSR samples. The forensic team first examined the cartridges and bullets through ballistics analysis. Using comparison microscopy, experts matched the fired bullets and cartridge casings to a specific firearm. Firearm examination confirmed that the casings and bullets originated from the same weapon, which was identified as a 9mm handgun. This step was vital in linking the suspect’s firearm to the crime scene evidence.

GSR analysis was employed to determine whether the suspect had recently discharged a firearm. GSR particles are composed of primer residues and metallic particles that deposit on a shooter’s hands and clothing when a gun is fired. In this case, GSR testing on the suspect’s hands yielded particles consistent with gunfire, supporting the assertion that the suspect had recently fired a weapon. Although GSR is not definitive proof of shooting, it provides corroborative evidence when combined with other forensic findings.

The use of NIBIN was instrumental in this case. NIBIN allows for the comparison of ballistic markings on bullets and cartridge casings across multiple crime scenes. The forensic analysts uploaded the evidence ballistics data into NIBIN, which generated a match with a previously recorded firearm used in other crimes. This linkage helped build a pattern suggesting the weapon’s involvement in multiple offenses, strengthening the case against the suspect. NIBIN’s database system significantly enhances the speed and accuracy of firearm investigations by facilitating rapid data sharing among law enforcement agencies.

Additional forensic evidence, such as fingerprint analysis on the firearm and the collection of DNA from the scene, supported the firearm evidence. However, the most compelling evidence came from the ballistic comparisons and GSR analysis, which directly associated the suspect with the firearm and the shooting incident.

In conclusion, forensic firearm examinations were central to the investigation of the Eastburn homicide. Ballistic analysis linked the firearm to the bullets and casings recovered from the scene, while GSR testing supported the suspect’s recent firearm use. The integration of NIBIN allowed law enforcement to connect the firearm to other crimes, broadening the scope of the investigation. This case exemplifies how forensic firearm evidence can be pivotal in solving homicides by providing reliable, scientific linkages between suspects, weapons, and crime scenes.
