The Difference Between “Aiding and abetting” & “Accessory to a crime” in Colorado

Posted on March 15, 2022

Aiding and abetting is helping someone commit a crime in Colorado, and it carries the same penalties as actually committing the crime.

By contrast, being an accessory to a crime (CRS 18-8-105) is assisting people who already committed a crime, such as hiding them from the police; being an accessory carries less harsh penalties than actually committing the crime.

What is Aiding and Abetting in Colorado?

In Colorado common law, people who aid and abet the commission of a crime are accomplices. Examples of aiding and abetting the commission of the offense are:

• Driving a bank robber to the bank
• Distracting a store cashier so a shoplifter can steal undetected
• Disabling a surveillance camera so a burglar can enter a home without being recorded

Under CRS 18-1-603, accomplices in Colorado are treated no differently than the principals – the people who physically executed the underlying crime. Principals and accomplices face the exact same criminal charges since they both contributed to the commission of the crime. Therefore, an aider of first-degree assault would face first-degree assault charges. And an abettor of second-degree assault would face second-degree assault charges, etc.

Though in practice, criminal law courts tend to impose lesser punishments on accomplices. So the accomplice who drove the thief to the store will probably face a lesser sentence than the actual thief even if they both get convicted of theft.

Under CRS 18-1-604, alleged accomplices can raise the following affirmative defense to criminal charges: They terminated their effort to help commit the crime, and they either:

• warned the police, or
• warned the victim

Also, a person’s mere presence at the scene of the crime does not automatically make him or her an accomplice to such crime.¹

What is an Accessory after the Fact in Colorado?

Under CRS 18-8-105, an accessory is someone who assists a person who has committed a crime – or who is suspected of committing a crime. In order to be convicted of being an accessory, the person must have had the intent to prevent or hinder the suspect from being arrested, prosecuted, convicted, or punished.

Example: Paul tells his friend Jack that he killed a person, and the police are on his tail. Jack agrees to let Paul hide out in his basement. Here, Jack is an accessory to Paul because he is assisting Paul by harboring and concealing him from the police.

Other examples of committing the crime of accessory under Colorado law include:

• warning a suspect that law enforcement officers are near;
• giving money, weapons, or transportation to a suspect;
• deceiving the police to throw them off the scent of a suspect;
• destroying physical or testimonial evidence of a crime;
• the performance of any act in an attempt to help a suspected criminal to escape justice

The punishment of such a person for being an accessory depends on the circumstances of the case:

Facts of the case	Colo. accessory penalties
The other person has been convicted of or charged with a class 1 or 2 felony criminal offense.	Class 4 felony: 2 to 6 years in prison (with 3 years mandatory parole), and/or A fine of $2,000 to $500,000
The other person is suspected of committing a class 1 or 2 felony, but has not been charged.	Class 5 felony: 1 to 3 years in prison (with 2 years mandatory parole), and/or A fine of $1,000 to $100,000
The other person has been charged with or is suspected of a class 3, 4, or 5 felony.	Class 5 felony: 1 to 3 years in prison (with 2 years mandatory parole), and/or A fine of $1,000 to $100,000
The other person has been charged with or is suspected of a class 6 felony.	Class 6 felony: 1 to 1 ½ years in prison (with a year mandatory parole), and/or A fine of $1,000 to $100,000
The other person has been charged with or is suspected of a misdemeanor.	Petty offense: Up to 10 days in jail, and/or A fine of up to $300

In short, accessories to a person who committed a felony are felons. But accessories to a person who committed a misdemeanor face only petty offense charges.

A common defense to accessory charges is that the defendant did not realize the other person was a criminal suspect. In other words, they lacked the required “mental state” and “specific intent” to help the principal escape justice. In any Colorado criminal case, the prosecution has the burden to prove guilt beyond a reasonable doubt.²
