In Colorado, there are varying degrees of murder.
The difference between first and second degree murder is whether the murder was committed with intent and after deliberation. First degree murder is a class one felony and is punishable by life in prison and may even be punishable by the death penalty if it is sought by prosecution. Manslaughter is a lower-level offense, but is still a felony.
There are potential defenses and affirmative defenses that may offer you protection. The prosecution must prove that you acted with a particular mental state. For example, first degree murder requires that you act with specific intent, not just knowingly or recklessly. Affirmative defenses, such as self defense, defense of others and intoxication may apply.
If you are facing these types of life-altering charges, it is imperative that you have an attorney who can carefully analyze your case.
