The Homicide Ladder: Murder, Manslaughter, and How to Organize a Criminal Law Answer

Homicide is a staple of Criminal Law exams. The fact patterns can be complicated, but the analysis follows a pattern: identify the killing, figure out the mental state, and place the crime on the ladder. Here's the common-law and modern statutory framework most courses teach.

The base: murder requires malice aforethought

At common law, murder is the unlawful killing of another human being with malice aforethought. Malice doesn't mean spite. It's satisfied by any of four mental states:

1. Intent to kill.
2. Intent to inflict serious bodily harm.
3. Depraved heart (reckless indifference to an unjustifiably high risk to human life).
4. Felony murder: a killing during the commission of an inherently dangerous felony.

If none of these is present, it's not murder.

Top rung: first-degree murder

Many states divide murder by statute. First-degree murder typically requires a premeditated and deliberate killing, meaning the defendant reflected on the killing, even briefly, and acted with a cool mind. Some statutes also treat killings by certain methods (such as poison or lying in wait) or during certain enumerated felonies as first-degree murder.

Felony murder

A killing that occurs during the commission or attempted commission of an inherently dangerous felony is murder, even if accidental. The classic list is burglary, arson, robbery, rape, and kidnapping. Limits to look for:

• The defendant must be guilty of the underlying felony.
• The felony must be independent of the killing (an assault that results in death usually can't serve as the predicate).
• The death must be a foreseeable result of the felony.
• Deaths after the defendant reached a place of temporary safety generally fall outside the rule.
• Under the majority "agency" approach, a co-felon isn't liable for a killing committed by a victim or police officer.

Second-degree murder

Murder that doesn't meet the first-degree requirements is typically second-degree murder. This usually covers intent-to-kill cases without premeditation, intent to cause serious bodily harm, and depraved-heart killings.

Voluntary manslaughter

An intentional killing is reduced to voluntary manslaughter when it's committed in the heat of passion. The elements:

• Adequate provocation that would arouse a sudden and intense passion in a reasonable person.
• The defendant was in fact provoked.
• There wasn't enough time for a reasonable person to cool off.
• The defendant didn't in fact cool off.

Many jurisdictions also recognize imperfect self-defense: a killing in self-defense where the defendant was the initial aggressor or honestly but unreasonably believed deadly force was needed.

Involuntary manslaughter

An unintentional killing is involuntary manslaughter when it results from criminal negligence (a gross deviation from reasonable care) or occurs during an unlawful act that doesn't qualify for felony murder (misdemeanor manslaughter).

How to write the answer

Start at the top and work down. State the definition of murder, test each form of malice against the facts, then ask whether any mitigating doctrine reduces it. Graders want to see that you considered the options and chose one based on the facts.
