Why Is Chain of Custody Important in a Criminal Case?

This article will highlight why a chain of custody is necessary to prove the authenticity of digital evidence and how VIDIZMO helps to serve that purpose.

Evidence integrity is as critical as placing criminals behind bars or doing justice to the innocent. Therefore, protecting the integrity of digital evidence is of utmost importance during a trial.

If the evidence integrity seems suspicious and data manipulation is detected, or it has been mishandled by law enforcement officers, it can easily be challenged on the grounds that it has been tampered with, which results in case closure (every law enforcement officer’s nightmare!!!).

According to the bill HB 287 introduced by Rep. Sam Garrison of Clay County:

“Tampering with or fabricating evidence is a second-degree felony in a criminal trial or investigation relating to felonies”

Law enforcement officers and other investigators are responsible to establish the chain of custody reports and handle digital evidence properly by following rules and regulations concerning the admissibility of evidence in court.

The chain of custody holds paramount importance when it comes to digital evidence authenticity as it proves that evidence is as original as collected at the crime scene.

This article clarifies why the chain of custody is important in a criminal case trial and the best tool that helps you to maintain the chain of custody and protect digital evidence in every step of criminal case proceedings.

What Is a Chain of Custody?

Before diving deeper into its importance, one needs to understand what a chain of custody is.

Chain of custody is the document of activities performed on digital evidence by tracking its control, transfer, access, analysis, and disposition during criminal cases.

It is crucial to maintain an unbroken chain of custody report to ensure that evidence is not compromised at any point from the time of collection to its court presentation. It shows who has collected and accessed digital evidence when the evidence was transferred etc.

What Information is provided by the Chain of Custody Report?

Typically, a chain of custody report must include the following information to maintain a detailed log of activities performed on digital evidence:

  • Name of the investigator or police officer
  • Who collected the evidence?
  • The user's email address.
  • Time and date when the changes have been done in the evidence.
  • Description of evidence
  • Relevant serial numbers or case numbers
  • Activities performed on the evidence, such as evidence has been uploaded, viewed etc.
  • The IP address of the user from where the changes have been made.

Why is Chain of Custody Important for Criminal Cases?

There is no need to say that digital evidence is a key element in solving criminal cases. In order to prove the defendant is guilty or not, prosecutors must justify that the evidence presented in the court is as original as collected at the crime scene.

If any discrepancies are found due to mishandling of digital evidence, it can be challenged anytime in the court and ruled inadmissible.

Nobody wants that!

Therefore, the chain of custody is more important than digital evidence itself as it proves the integrity of evidence in court. Contrary to that, if at any point the chain of custody is broken or if it has failed to prove that it is original, then the court will declare it inadmissible.
