Handling Evidence Is Done For Several Reasons

Handling Evidence Is Done For A Number Of Reasons A

Handling evidence is done for a number of reasons. After it is photographed, drawn in the crime scene sketch, and listed in the crime scene notes, it should be processed. There may be an analysis done at the scene and packages for storage in the evidence repository, or the evidence may be collected for transportation to the crime laboratory for further analysis. Control of the evidence for accountability purposes is done using a document known as the chain of custody. The chain of custody reflects the travel of the evidence through the criminal justice system including where it was obtained, who had control of it from the law enforcement agency that collected it, the evidence custodians who received it, the laboratory technician who analyzed it, the court clerk who held it as an exhibit during the trial, and finally the method of disposal when the evidence was no longer needed as evidence.

You are part of a crime scene unit conducting a crime scene search and processing. At the scene, you find a Colt, .45 caliber, model 1911A1 pistol with the serial number eradicated. There are seven rounds of .45 Remington Peters full metal jacket bullets in the magazine. There is a live round in the chamber of the pistol, and the hammer is cocked with the safety off. The pistol has been photographed, drawn in the sketches, and notes on the pistol have been completed.

Introduction

The handling of firearms as evidence in criminal investigations demands meticulous procedures to ensure integrity, traceability, and reliability of the evidence presented in court. This paper explores the process following the discovery of a firearm—specifically a Colt .45 caliber 1911A1 with an erased serial number—focusing on its processing, packaging, analysis, and ultimate disposition after legal proceedings conclude. Additionally, attention is given to the chain of custody, laboratory testing, and the importance of proper evidence handling during the judicial process.

Initial Processing and Crime Scene Handling

Once the firearm is located at the crime scene, law enforcement personnel must carefully document its condition. Photographs capturing multiple angles are essential to preserve the firearm's appearance at the scene. Detailed sketches are made, noting the firearm’s position, and written notes record salient features such as the absence of a serial number, the presence of a live round chambered, and the condition of the hammer and safety. Handling procedures require wearing gloves to avoid contamination or damage, and any movement of the firearm should be recorded accurately to establish a chain of custody from the moment of discovery.

Packaging and Transportation

Proper packaging is critical to avoid damage and preserve evidence integrity. Firearms are usually wrapped in anti-static paper or placed in a rigid, transparent container to prevent physical damage. The firearm should be secured in a manner that prevents movement during transport. In addition, packaging should be labeled with case number, evidence tag, and handling instructions. Chain of custody forms are attached, documenting each person who handles the firearm from seizure to storage. The packaging process must adhere to forensic standards to maintain the evidence's admissibility in court.

Analysis in the Crime Laboratory

In the laboratory, forensic analysts first verify the evidence’s identification, ensuring that the firearm matches descriptions from the scene. Specialized tests may include:

  • Ballistics examination to compare cartridge cases and bullets recovered from the scene with the firearm, using comparison microscopy.
  • GSR (gunshot residue) collection to determine if the suspect handled or fired the weapon.
  • Forensic tests to detect and possibly restore the erased serial number, such as chemical etching or digital imaging techniques.
  • Determination of the firearm’s function and testing to verify its operational status when applicable.

These analyses help establish whether the firearm was used in the commission of a crime, link it to other evidence, and provide investigative leads.

Testimony and Chain of Custody

When testifying in court, forensic experts explain how the firearm was processed, sealed, and analyzed, emphasizing adherence to protocol. They describe the chain of custody, explaining each individual responsible for the firearm’s safekeeping, from initial seizure to laboratory analysis. Ensuring the integrity of this chain is vital for the evidence to be credible and admissible.

Disposal after Court Proceedings

After the legal process concludes, and there are no appeals pending, the firearm is disposed of following established legal protocols. Typically, law enforcement agencies may destroy firearms, especially those involved in crimes, or return them to the owner if lawful and appropriate. If the firearm is barred from firearms ownership, it may be rendered inoperable or properly destroyed to prevent misuse. Proper documentation of disposal must be maintained, including verification that all legal and procedural requirements were met.

Conclusion

The process of handling, analyzing, and disposing of firearms as evidence is rigorous and governed by strict standards to maintain integrity within the criminal justice system. Proper documentation, packaging, laboratory testing, and chain of custody management are essential for ensuring that the evidence withstands judicial scrutiny. By following these protocols, forensic investigators contribute to the pursuit of justice while safeguarding the rights of individuals involved.
