noun

mur·​der ˈmər-dər 

plural murders

1

: the crime of unlawfully and unjustifiably killing a person

an attempted murder

specifically, law : such a crime committed under circumstances defined by statute

Under Minnesota law, third-degree murder is defined as causing the death of a person "by perpetrating an act eminently dangerous to others and evincing a depraved mind" without regard for life or intent to kill. A conviction on this count carries a prison sentence of up to 25 years. Second-degree murder, according to Minnesota law, is charged when the defendant intentionally kills someone, albeit without preparing to do so ahead of time. (Premeditation would warrant a first-degree murder charge).

Legal Definition

murder

1 of 2 noun

mur·​der ˈmər-dər 

: the crime of unlawfully and unjustifiably killing another under circumstances defined by statute (as with premeditation)

especially : such a crime committed purposely, knowingly, and recklessly with extreme indifference to human life or during the course of a serious felony (as robbery or rape) compare cold blood, cooling time, homicide, manslaughter

Note: Self-defense, necessity, and lack of capacity for criminal responsibility (as because of insanity) are defenses to a charge of murder. Most state statutes and the U.S. Code divide murder into two degrees. Florida, Minnesota, and Pennsylvania currently have three degrees of murder. Some states do not assign degrees of murder.

— depraved-heart murder \ di-​ˈprāvd-​ˈhärt-​ \

— felony murder

: a murder that occurs in the commission of a serious felony (as burglary or sexual battery) compare misdemeanor-manslaughter at manslaughter

Note: Felony murder is usually considered first-degree murder. Felony murder does not require specific intent to kill, and an accessory to the felony may also be charged with the murder.

— first-degree murder

: a murder that is committed with premeditation or during the course of a serious felony (as kidnapping) or that otherwise (as because of extreme cruelty) requires the most serious punishment under the law
