The significance of labelling and sealing an evidence bag cannot be overstated in the current era.

This crucial step ensures the preservation of evidence integrity. It plays a pivotal role in legal proceedings and upholds the chain of custody.

Thus, safeguarding the rights of all parties involved.

The Importance of Proper Evidence Bag Labelling and Sealing

Imagine a scenario where evidence is mishandled, misplaced, or tampered with during an investigation. This nightmare can become a reality when the chain of custody is compromised.

The chain of custody is the chronological documentation of the custody, control, transfer, analysis, and disposition of physical evidence. It is the backbone of maintaining evidence integrity. Thus, ensuring that evidence remains unaltered and trustworthy throughout its journey.

A break in the chain of custody can have severe consequences. Thus, leading to the exclusion of crucial evidence or the dismissal of a case altogether. To prevent such mishaps, meticulous labelling and sealing of evidence bags are imperative.

The Purpose of Tagging and Labelling Items of Evidence

Understanding why we tag and label evidence is essential. Here are some key reasons behind these practices:

Documentation for Legal Proceedings

In a court of law, clear and accurate documentation is paramount. Evidence bags serve as legal documents that record essential information. Thus, making it easier for lawyers, judges, and juries to comprehend the facts of a case. This documentation can make or break an investigation, as it forms the basis for presenting evidence in court.

Chain of Custody Establishment

Properly labelled and sealed evidence bags establish a secure chain of custody. Each label, tag, and seal acts as a link in this chain, documenting who handled the evidence and when. Any deviation from this chain can raise doubts about evidence integrity.

Preservation and Protection of Evidence

Evidence, once collected, must be preserved in its original condition. Proper labeling and sealing shield evidence from contamination, damage, or tampering. They help maintain the integrity of biological samples, trace evidence, and physical items, ensuring they remain viable for analysis.

Efficient Identification When Needed

Imagine a storage room filled with countless evidence bags. How do investigators locate a specific piece of evidence among this sea of bags? Proper labeling comes to the rescue. Case numbers, descriptions, and collector information allow for efficient retrieval when needed.

Understanding the Chain of Custody

Now, let’s explore the chain of custody in more detail.

Definition and Explanation:

The chain of custody is the documented trail of everyone who has possessed the evidence. It provides a clear picture of where the evidence has been, who has handled it, and when it changed hands. This transparency is crucial for maintaining evidence integrity and ensuring a fair legal process.

Ensuring Evidence Integrity:

A pristine chain of custody is essential for upholding the credibility of evidence. Any break in this chain, no matter how small, can cast doubt on the evidence’s authenticity and admissibility in court. It’s a safeguard against mishandling, tampering, or unauthorized access.

Consequences of a Break in the Chain of Custody:

When the chain of custody is compromised, the consequences can be dire. Evidence can be rendered inadmissible, severely impacting the prosecution’s case. To avoid such setbacks, the chain of custody must be meticulously maintained, starting with the proper labeling and sealing of evidence bags.

Information Required for Tagging

Let’s get into the specifics of what information should be included on the evidence tag:

Case Information:

  • Case number: A unique identifier for the case.
  • Date: When the evidence was collected.
  • Location: Where the evidence was found.

Description of Evidence:

  • Size: The physical dimensions of the item.
  • Color: The item’s color.
  • Markings: Any distinctive markings or features.
  • Unique Characteristics: Notable aspects that distinguish the item.

Collector Information:

  • Name: The name of the person collecting the evidence.
  • Badge Number: Their official identification.
  • Contact Details: Contact information for the collector.

Collection Date and Time:

The precise moment when the evidence was collected is crucial for the chain of custody.

Location of Collection:

Documenting where the evidence was found ensures its context is preserved.

Any Relevant Remarks or Observations:

Include any additional information that may be pertinent to the investigation. It may include the condition of the evidence or its potential relevance.

Information Marking on the Outside of the Evidence Package

The exterior of the evidence package is not to be overlooked. It serves as a safeguard against tampering and helps with quick identification.

Case Number:

This should be prominently displayed to facilitate easy retrieval.

Seal for Tamper-Evident Security:

Using tamper-evident seals adds an extra layer of protection. Any attempt to open the bag will leave visible evidence of tampering.

Chain of Custody Documentation for Custody Transfers:

Whenever custody of the evidence changes hands, document it on the exterior of the package. This ensures transparency in the chain of custody.

Proper Labeling Process

Now that we understand what information to include, let’s go through the step-by-step process of labeling an evidence bag effectively.

Case Number Placement:

Place the case number at the top of the label, making it highly visible.

Detailed Description:

Provide a thorough description of the evidence, including size, color, markings, and unique characteristics.

Collector’s Information:

Include the collector’s name, badge number, and contact details.

Collection Date and Time:

Document when the evidence was collected and at what time.

Location and Remarks:

Clearly state where the evidence was found and note any relevant remarks or observations.

Sealing the Evidence Bag

Sealing the evidence bag is the final step in ensuring its security and integrity.

Using Tamper-Evident Seals:

Choose tamper-evident seals that are designed to show any signs of interference. When sealing the bag, ensure it is tightly closed, and the seal is intact.

Documenting the Seal:

Record the seal number and the person applying it. This creates an additional layer of accountability in the chain of custody.


In the realm of criminal investigations, attention to detail is paramount. Properly labeling and sealing evidence bags are critical steps in upholding the integrity of evidence. They ensure a fair legal process.
