List of punishments for murder in the United States

Murder, as defined in common law countries, is the unlawful killing of another human being with intent (or malice aforethought), and generally this state of mind distinguishes murder from other forms of unlawful homicide (such as manslaughter). As the loss of a human being inflicts an enormous amount of grief for individuals close to the victim, as well as the fact that the commission of a murder permanently deprives the victim of their existence, most societies have considered it a very serious crime deserving of the harshest punishment available. Typically a convicted murder suspect is given a life sentence or even the death penalty for such an act. A person who commits murder is called a murderer, and the penalties, as outlined below, vary from state to state. 
In 2012, the United States Supreme Court held in "Miller v. Alabama" that mandatory sentences of life without the possibility of parole are unconstitutional for juvenile offenders.

Ohio differentiates between "Aggravated Murder" and "Murder." Aggravated Murder consists of purposely causing the death of another (or unlawful termination of a pregnancy) with prior calculation and design, or purposely causing the death of another under the age of 13, a law enforcement officer, or in the course of committing certain serious felony offenses. Murder consists of purposely causing the death of another, or causing the death of another as a proximate result of committing certain serious felony offenses.
