What happens if the chain of custody is broken? This is a critical question in today's legal world. Discover the consequences, significant contributors, and prevention strategies for a broken chain of custody in digital evidence.
Digital evidence has become crucial in criminal cases. Based on a survey of police chiefs, agency managers, examiners, investigators, and prosecutors, 66% believe digital evidence has taken over physical evidence. This shift has led to questions like, "What happens if the chain of custody is broken?"
Imagine a critical criminal case involving digital evidence. Once the evidence is presented in court, doubts could emerge about its authenticity due to a broken chain of custody. From there, the case could go either way. A guilty person might be acquitted, or an innocent person might be wrongly convicted, all due to the prosecutor's inability to prove the chain of custody.
With the increasing use of digital evidence comes the significant challenge of maintaining its integrity. In court, a broken chain of custody renders evidence inadmissible. Understanding the repercussions of a broken chain of custody is extremely important for someone working with and handling digital evidence.
In 2017, in the case of Brown v. The State, authorities used digital evidence from various social media sources, including photographs and videos, to convict the defendant. However, the defense challenged the authenticity of the digital evidence and filed a motion for a new trial. As a result, the court then overturned the entire decision. This case highlights how digital evidence often faces scrutiny over its authenticity. If a crucial case can be overturned based solely on the authenticity of social media sources, imagine the repercussions of a broken chain of custody on evidence admissibility in court.
Throughout this blog, we will address the key question of what happens if the chain of custody is broken. We will highlight the repercussions of a broken chain of custody, identify key factors that contribute to it, and explore existing solutions to this challenge.
Chain of custody refers to the chronological documentation or paper trail that records the sequence of custody, control, transfer, analysis, and disposition of physical or digital evidence.
The primary purpose of the chain of custody is to establish that the evidence presented in court is preserved in the same state as initially collected. When a chain of custody is broken, it creates doubts regarding its handling, tampering, and integrity.
In legal proceedings, a broken chain of custody can have serious consequences, as it can cast doubt on the integrity of the evidence, potentially rendering it inadmissible evidence.
The concept of the chain of custody is critical in criminal cases because these cases often show us what happens if the chain of custody is broken. In such instances, the authenticity of the evidence becomes a critical factor in determining the case's outcome. If there are any doubts about whether the evidence has been tampered with or altered, it can lead to the evidence being deemed inadmissible. This can significantly impact the case.
However, custody is particularly crucial when it comes to digital evidence. Unlike physical evidence, digital evidence can be easily manipulated, altered, or tampered with. This makes it even more susceptible to challenges regarding its authenticity. As a result, a broken chain of custody in digital evidence raises doubts about its integrity and could render critical evidence inadmissible, potentially jeopardizing the entire case.
An unbroken chain of custody is vital in preserving the integrity and credibility of evidence throughout the legal process. Likewise, a broken chain of custody can jeopardize the entire case and make inadmissible evidence. To that end, let's examine what happens when the chain of custody is broken and highlight why it is essential.
With a broken chain of custody, the integrity of the evidence becomes compromised. As a result, courts can no longer confidently regard the evidence as unaltered or tamper-free.
Any gap or inconsistency in the custody record immediately raises doubts about whether the evidence has been manipulated, contaminated, or otherwise affected. Consequently, this broken chain of custody undermines the reliability of the evidence. As a result, the value of the evidence in supporting the case is significantly diminished.
One of the most severe repercussions of a broken chain of custody is the risk of evidence being deemed inadmissible in court. Courts require evidence to have a clear link to the crime and to be free from any reasonable doubt about its authenticity.
When someone disrupts the chain of custody, it can significantly hinder the prosecution's ability to prove that the evidence is genuine and untampered. As a result, the judge may rule the evidence inadmissible, preventing it from being used to support the case.
Additionally, specific laws demand strict adherence to the chain of custody. For example, the Federal Rules of Evidence (FRE) outlines procedures related to evidence handling.
Compliance with FRE Rule 901 requires that evidence be appropriately authenticated to be admissible. A broken chain of custody can lead to failure to meet this requirement. This further increases the risk of evidence exclusion in court.

A broken chain of custody can severely undermine a case's outcome. When critical evidence is excluded, the prosecution may struggle to prove the case beyond a reasonable doubt. Because of this, the court may reduce charges, accept plea bargains, or dismiss the case entirely.
In criminal cases, this could lead to a guilty party being acquitted. In civil cases, it might mean the dismissal of key evidence that could have swayed the judgment in favor of the plaintiff. Ultimately, the outcome of the entire case can be jeopardized. This failure in maintaining the chain of custody can lead to a significant miscarriage of justice.
A broken chain of custody often leads to heightened legal disputes and increased appeals. The defense can quickly challenge the validity of compromised evidence, leading to extensive litigation. This prolongs the legal process and raises costs for both parties.
In some cases, a conviction based on questionable evidence may be overturned on appeal. This can result in retrials or even the release of convicted individuals. Moreover, these disputes can be lengthy and complex, further burdening the judicial system.
A broken chain of custody can severely undermine the credibility of those responsible for handling evidence, including law enforcement agencies, forensic experts, and the prosecution.
A failure to provide substantial evidence can lead to broader doubts about the integrity of evidence in other cases they handle. This can weaken confidence in the legal process and thus increase the risk of inadmissible evidence in court.
Now that we’ve partially answered the question, “What happens if the chain of custody is broken?” it’s crucial to delve into the factors contributing to this issue. A broken chain of custody can lead to serious consequences, including inadmissible evidence, compromised case outcomes, and a significant loss of public trust. Therefore, understanding the causes behind these breaks is vital to maintaining the integrity of the legal process.
Several key factors can contribute to a broken chain of custody. Each step in handling evidence presents opportunities for errors that can jeopardize the entire case. So, let's examine the critical factors that often lead to these breaks and discuss how they can be prevented to ensure evidence remains credible and admissible in court.
Errors in seizing and preserving evidence are often the first point that can lead to a broken chain of custody. If digital evidence is not collected and preserved correctly, its authenticity may be questioned immediately.
Therefore, it's important to preserve digital evidence in its original state when collecting it. For collection, it's important to store evidence securely in an encrypted storage medium to preserve its authenticity and prevent any alteration.
But the collection of evidence isn't enough. It's also important to make sure that evidence is properly preserved. Preservation often involves creating an exact copy or image of the digital data, often called a forensic image. This ensures the original device or data source remains unaltered.
Once digital evidence is collected, it must be stored securely to prevent any risk of tampering or unauthorized access. Improper storage solutions can compromise the integrity of the evidence, leading to a broken chain of custody. For digital evidence, this often means ensuring that the storage environment is secure and encrypted.
Encryption is a key aspect of secure storage. Encryption standards like AES protect data by converting it into an unreadable format. Only those with the correct encryption key can decrypt and access the data. Typically, AES uses 256-bit encryption, providing a high level of security that is nearly impossible to breach.
Another critical factor in preventing a broken chain of custody is implementing strict access control measures. Digital evidence must be accessible only to authorized personnel to ensure its integrity. When access controls are inadequate, or there is no tracking for who interacted with the evidence, the integrity of the evidence can be compromised.
One effective way to manage access is through Role-Based Access Control (RBAC). RBAC restricts access to evidence based on the role assigned to them and the permissions that come with it. This ensures that only those with the necessary clearance can view or handle the evidence. Limiting access in this way dramatically reduces the likelihood of unauthorized handling.
The transfer of evidence between locations or individuals is a vulnerable point in the chain of custody. These gaps can be exploited in court, potentially leading to the evidence being ruled as inadmissible evidence. Ensuring a safe and secure transfer is crucial in preventing a broken chain of custody.
To ensure the safe and secure transfer of evidence, end-to-end encryption is essential. This ensures the data remains encrypted throughout the transfer process, safeguarding it from unauthorized access or tampering.
A detailed and accurate log is the backbone of the chain of custody. Every action taken with the evidence must be meticulously recorded, from the moment of collection to its presentation in court. Gaps in this can lead to serious doubts about the evidence's authenticity, making it easier for the defense to challenge its admissibility as inadmissible evidence.
Unfortunately, some law enforcement agencies neglect the importance of maintaining a detailed audit trail, leading to significant challenges for prosecutors. Without a comprehensive audit trail, the integrity of the evidence is questioned, increasing the risk of it being ruled as inadmissible evidence. This weakens the prosecution's case and undermines the entire legal process.
Improper handling or any indication of tampering with evidence is one of the most common causes of a broken chain of custody. Law enforcement agencies and legal professionals must manage evidence according to strict protocols established by various evidence-handling laws to prevent contamination or alteration.
These include the Federal Rules of Evidence (FRE), National Institute of Standards and Technology (NIST) Guidelines, and Federal Rules of Civil Procedure (FRCP). Laws like this help prevent and identify deviations in digital evidence, such as tampering, mishandling, or lost evidence.
Tampering of evidence can also become a significant concern if there are no ways to track it. This is where tamper detection can help by acting as the first step in preventing any alteration in digital evidence. Advanced technology like SHA (Secure Hash Algorithm) Cryptography present in modern digital evidence management systems helps detect tampering. This helps identify and stop evidence tampering and maintain the integrity of the chain of custody.
As we have seen, maintaining a consistent chain of custody is critical in preserving the integrity of digital evidence. Best practices for digital evidence include appropriate collection and preservation in a secure format, secure handling procedures, detailed audit trails, and tampering prevention measures.
These days, these measures can be implemented by using a secure storage solution for digital evidence, such as a digital evidence management system.

Digital evidence management systems securely manage, track, and preserve digital evidence from the moment investigators collect it to its presentation in court.
These tools are specifically designed to tackle the challenge of maintaining the authenticity of evidence. Unlike conventional approaches, digital evidence management systems prevent evidence silos by centralizing and automating management workflows, which helps tracks the digital chain of custody from the moment investigators collect the evidence to its presentation in court.
This automation reduces resource occupancy and ensures that digital evidence remains intact and traceable. This also explains why 35% of law enforcement personnel have adopted digital evidence management systems.
Digital evidence management systems come equipped with advanced security features, including end-to-end encryption using AES and tamper detection using SHA cryptography. This helps protect digital evidence at every stage. Additionally, digital evidence management systems also come equipped with role-based access control to ensure that only authorized personnel can interact with digital evidence. This helps further reduce the risk of a broken chain of custody.
These technologies are crucial in maintaining the chain of custody for digital evidence and preventing it from becoming inadmissible in court.
The key question of "What happens if the chain of custody is broken?" remains a pressing concern for law enforcement and legal professionals. Without addressing it, the integrity of evidence and the entire criminal justice system could be called into question.
The solution to this problem lies in appropriately handling, storing, and transferring digital evidence. Modern digital evidence management systems significantly mitigate this issue by providing a centralized, secure, and trackable solution for digital evidence.
Such software provides a detailed audit trail with automated logging, including time-stamped records and immutable logs, showing who accessed the evidence and when it was accessed.
