New Mexico First-Degree Murder

In New Mexico, the most serious type of homicide is first-degree murder. It's defined as the killing of another human being through a willful, deliberate, and premeditated act. Under certain circumstances, an intentional killing may not be considered first-degree murder if there was a mitigating circumstance.

For example, a husband who comes home to find his wife cheating on him may become enraged and in that instant, decide to shoot and kill her. In this example, the husband committed the killing under the heat of passion and may be charged with second-degree murder rather than first degree murder due to the mitigating circumstance.

The crime of first-degree murder also includes killings which occurred while committing or attempting to commit a felony or while performing any act that is greatly dangerous to the lives of others and shows a depraved mind with no regard for human life. First-degree murder is a capital felony which means that it has the steepest penalties, including life imprisonment without parole. New Mexico abolished the death penalty in 2009. As such, a first-degree murder conviction may not be penalized by death. The following is a quick summary of New Mexico's first-degree murder laws.
