Being an accomplice to murder in Illinois means you can be charged with and convicted of murder even if you did not pull the trigger or directly cause anyone’s death. Under 720 ILCS 5/5-2, Illinois law holds a person legally accountable for the conduct of another when they aid, agree to aid, or attempt to aid in the planning or commission of an offense with the intent to promote or facilitate it. This is known as accountability, and it is one of the most serious and far-reaching aspects of Illinois criminal law.

What Is Illinois’ Accountability Law and How Does It Apply to Murder?
Illinois does not use the traditional term “accomplice liability” in its statutes. Instead, the state uses the concept of accountability. What makes the law especially powerful is the common design rule. Under this rule, when two or more people engage in a common criminal plan, any act done by one person to carry out that plan is considered the act of everyone involved. All of them can be held equally responsible for the consequences.
