Tampering with Physical Evidence in Colorado – C.R.S. § 18-8-610

Colorado Revised Statute § 18-8-610 C.R.S. makes it a crime to tamper with physical evidence. This means to alter, destroy, conceal, or falsify physical evidence so as to prevent it from being available at an upcoming official proceeding, such as a trial or sentencing hearing. Tampering with physical evidence can be a felony or a misdemeanor depending on the type of case the evidence was being used for. There are several reasons why someone would want to tamper with physical evidence. A defendant facing criminal charges may want to destroy any evidence of their criminal activity. Or someone may seek to implicate another person for a crime they did not commit and to alter or plant false evidence to be used against them in court.

1. Tampering Defined

For you to be convicted of tampering with evidence in Colorado, prosecutors must prove beyond a reasonable doubt the following two elements:

1. You believe that an official proceeding is pending or about to be instituted, and
2. You either:
   • destroyed, hid, removed, or changed physical evidence with the intent to impair its verity or availability in an official proceeding; or
   • made, presented, or offered false or altered evidence with the intent that it be used in an official proceeding.¹

“Official Proceeding” Meaning

An official proceeding generally refers to court proceedings, including civil or criminal trials. It may also include an:

• arraignment,

Physical evidence may also consist of electronic records, videos, or audio recordings. This includes emails, text messages, social media messages, image files, video files, and computer files. However, physical evidence does not include human body parts or human remains.²

Frequently Asked Questions

What exactly counts as “physical evidence” that could get me in trouble for tampering?

Physical evidence includes any article, object, document, record, or thing of physical substance. This covers electronic records like emails, text messages, social media posts, photos, videos, and computer files. However, it does not include human body parts or remains.

How do prosecutors prove I knew there was going to be a court case when I allegedly tampered with evidence?

Prosecutors must prove you believed an official proceeding was pending or about to start. This includes any court case, hearing, grand jury proceeding, or government agency hearing. They don’t need to prove a case was already filed, just that you believed one was coming.

What is the difference between a felony and misdemeanor charge for evidence tampering?

The penalty depends on the type of case the evidence relates to. If you tampered with evidence for a felony crime, you face a class 6 felony (12 to 18 months in prison). If it’s for a misdemeanor crime, you face a class 1 misdemeanor (up to 364 days in jail).

Can I get this conviction removed from my record later?

Yes, you can petition to seal your record three years after your case closes for both felony and misdemeanor convictions. If your charges are dismissed, you can petition for a record seal right away.
