8.2 Common Law & Statutory Homicide and Crimes Against the Person
Key Takeaways
- Common law murder is the unlawful killing of a human being with malice aforethought, established via four mental states: (1) intent to kill, (2) intent to inflict grievous bodily harm, (3) depraved heart reckless indifference, or (4) felony murder.
- The Felony Murder Rule (FMR) imposes strict liability for killings occurring during inherently dangerous felonies (BARRK: Burglary, Arson, Robbery, Rape, Kidnapping), subject to the merger doctrine (assaultive felonies merge) and agency theory limitations (majority rule: felon not liable for lethal acts of non-felons).
- Voluntary manslaughter is an intentional killing mitigated by adequate provocation in the heat of passion (objective reasonable person standard, sudden quarrel, mutual combat; no cooling-off period) or imperfect self-defense.
- Involuntary manslaughter encompasses unintentional killings resulting from criminal negligence (gross deviation from reasonable care) or the misdemeanor-manslaughter (unlawful act) doctrine.
- Crimes against the person include Battery (unlawful application of force causing injury or offensive contact), Assault (attempted battery or intentional creation of reasonable apprehension of imminent harm), False Imprisonment, and Kidnapping (confinement + asportation/concealment).
8.2 Common Law & Statutory Homicide and Crimes Against the Person
Homicide is the killing of one human being by another. At common law, criminal homicide is divided into Murder, Voluntary Manslaughter, and Involuntary Manslaughter. Modern statutory schemes, following the Pennsylvania Model and the Model Penal Code, further subdivide murder into First-Degree and Second-Degree Murder.
1. Common Law Murder & Malice Aforethought
Common law murder is defined as the unlawful killing of a living human being with malice aforethought and without justification or mitigation.
+-----------------------------------------------------------------------------+
| THE FOUR STATES OF MALICE AFORETHOUGHT |
| |
| 1. INTENT TO KILL (EXPRESS MALICE) |
| - Purpose or knowledge that conduct will cause death. |
| - DEADLY WEAPON DOCTRINE: Intent to kill may be inferred from the |
| intentional use of a deadly weapon directed at a vital part of body. |
| |
| 2. INTENT TO INFLICT GRIEVOUS / GREAT BODILY HARM (GBH) |
| - Conscious desire or knowledge that conduct will cause severe, |
| permanent, or life-threatening physical injury. |
| |
| 3. DEPRAVED HEART / ABANDONED & MALIGNANT HEART |
| - Extreme reckless indifference to an unjustifiably high risk to human |
| life (e.g., firing a weapon into an occupied crowd, dropping heavy |
| cinderblocks off a highway overpass, playing Russian roulette). |
| |
| 4. FELONY MURDER RULE (FMR) |
| - Any killing occurring during the commission or attempted commission |
| of an inherently dangerous underlying felony. |
+-----------------------------------------------------------------------------+
2. The Felony Murder Rule (FMR) & Doctrinal Limitations
Under the Felony Murder Rule, a death resulting from the commission or attempted commission of an inherently dangerous felony is classified as murder, with malice implied from the intent to commit the underlying felony.
+-----------------------------------------------------------------------------+
| THE INHERENTLY DANGEROUS FELONIES |
| |
| B - Burglary |
| A - Arson |
| R - Robbery |
| R - Rape (and other violent sexual offenses) |
| K - Kidnapping |
+-----------------------------------------------------------------------------+
Doctrinal Limitations on Felony Murder
-
The Merger Doctrine (People v. Ireland): The underlying felony must be independent of the homicide. If the underlying felony is an integral, assaultive crime (e.g., aggravated assault, aggravated battery, shooting into an occupied building, manslaughter), the felony merges with the homicide and cannot serve as the predicate for felony murder.
-
Temporal & Spatial Scope (The Res Gestae Rule): The lethal act must occur between the initial attempt to commit the felony and the termination of the felony. The felony continues during immediate escape until the felons reach a point of temporary safety (a place of relative security with unbroken chain of flight).
-
Causation and Third-Party Killings:
- Agency Theory (Majority Rule): The lethal shot must be fired by a felon or a co-felon (an agent of the criminal enterprise). If a police officer, security guard, or crime victim fires the fatal bullet that kills an innocent bystander or a co-felon, the surviving felons are not guilty of felony murder under the agency approach.
- Proximate Cause Theory (Minority Rule): The felons are liable for any death proximately caused by the felony, even if the fatal shot was fired by a police officer or resisting victim.
- The Redline Rule: In almost all jurisdictions, when a co-felon is lawfully killed by a police officer or resisting victim, the surviving co-felons are not liable for felony murder of their deceased accomplice.

+-----------------------------------------------------------------------------+
Statutory Degrees of Murder
- First-Degree Murder:
- Premeditated and Deliberate: The defendant made a conscious decision to kill after a period of reflection (premeditation), acting with a cool and dispassionate mind (deliberation). Even a brief moment of cool reflection suffices.
- Statutory Enumerated Felony Murder: Killings during statutorily designated felonies.
- Second-Degree Murder: All other common law murders, including depraved heart killings, intent to inflict grievous bodily harm, non-enumerated felony murders, and intentional killings lacking premeditation and deliberation.
Voluntary Manslaughter: Heat of Passion & Imperfect Self-Defense
Voluntary manslaughter is an intentional killing that would otherwise constitute murder, but is mitigated because the killer acted under the influence of extreme emotional disturbance or adequate provocation.
+-----------------------------------------------------------------------------+
| FOUR ELEMENTS OF ADEQUATE PROVOCATION MITIGATION |
| |
| 1. OBJECTIVE ADEQUATE PROVOCATION |
| - Provocation that would arouse sudden and intense passion in an |
| ordinary reasonable person, causing them to lose self-control. |
| - Recognized: Sudden physical assault, mutual combat, discovering a |
| spouse in the act of adultery. (Mere insulting words are INSUFFICIENT|
| unless accompanied by conduct or severe informational revelation). |
| |
| 2. SUBJECTIVE PROVOCATION |
| - Defendant was ACTUALLY provoked and acted in the heat of passion. |
| |
| 3. NO OBJECTIVE COOLING-OFF PERIOD |
| - An ordinary reasonable person would not have cooled off between the |
| provocation and the lethal act. |
| |
| 4. NO SUBJECTIVE COOLING OFF |
| - Defendant did not ACTUALLY cool off before committing the killing. |
+-----------------------------------------------------------------------------+
- Imperfect Self-Defense: In many jurisdictions, if a defendant kills with an honest but unreasonable belief in the necessity of deadly self-defense, or if the defendant was the initial aggressor with non-deadly force, murder is mitigated to voluntary manslaughter.
Involuntary Manslaughter
An unintentional killing committed without malice under either of two theories:
- Criminal Negligence: The defendant acted with gross negligence—a gross deviation from the standard of care that a reasonable person would observe (higher than civil tort negligence, but lower than depraved heart recklessness).
- Unlawful Act / Misdemeanor-Manslaughter Doctrine: A death occurring during the commission of an unlawful act not amounting to an inherently dangerous felony (typically a malum in se misdemeanor or non-dangerous felony).
| Offense | Required Mental State | Distinguishing Characteristics |
|---|---|---|
| First-Degree Murder | Premeditated & Deliberate intent to kill, or statutory FMR. | Requires cool reflection or specific statutory enumerated felony. |
| Second-Degree Murder | Malice aforethought (Intent to kill, GBH, Depraved Heart, FMR). | All common law murders lacking first-degree statutory elements. |
| Voluntary Manslaughter | Intent to kill or GBH, but mitigated. | Adequate provocation / heat of passion or imperfect self-defense. |
| Involuntary Manslaughter | Criminal Negligence or Unlawful Act. | Unintentional killing without malice (gross negligence or misdemeanor). |
4. Other Crimes Against the Person
+-----------------------------------------------------------------------------+
| CRIMES AGAINST THE PERSON SUMMARY |
| |
| BATTERY (General Intent) |
| - Unlawful application of force to another person resulting in either: |
| 1. Bodily injury; OR |
| 2. Offensive touching (unpermitted contact with victim's person/apparel)|
| - Need not be direct physical contact (e.g., throwing liquid, dog attack).|
| |
| ASSAULT (Specific or General Intent) |
| - TWO INDEPENDENT COMMON LAW FORMS: |
| 1. Attempted Battery (Specific Intent): Attempting an unlawful battery |
| (victim awareness NOT required). |
| 2. Apprehension Assault (General/Specific Intent): Intentional creation |
| of reasonable apprehension of imminent bodily harm (awareness REQUIRED)|
| |
| FALSE IMPRISONMENT (General Intent) |
| - Unlawful confinement of a person without valid consent within a bounded |
| area, where victim is aware of confinement or harmed by it. |
| |
| KIDNAPPING (General Intent) |
| - Unlawful confinement of a person involving either: |
| 1. MOVEMENT / ASPORTATION of the victim (even slight movement that |
| increases danger or facilitates concealment); OR |
| 2. CONCEALMENT of the victim in a secret place. |

Two armed individuals entered a commercial convenience store to commit an armed robbery. The store owner pulled a licensed firearm from beneath the counter and fired at the robbers. The bullet missed the robbers, struck an innocent customer standing near the entrance, and killed the customer instantly. Both robbers were apprehended at the scene. In a jurisdiction that adheres to the majority agency theory of felony murder, are the robbers guilty of felony murder for the customer's death?
A patron was sitting quietly at a restaurant counter when an acquaintance entered, walked up to the patron, and began shouting severe verbal insults, mocking the patron's deceased parents with vulgar slurs. Enraged by the offensive remarks, the patron immediately stood up, drew a concealed handgun, and shot the acquaintance in the chest, killing him instantly. The patron was charged with murder. At trial, the patron requested a jury instruction on voluntary manslaughter based on heat of passion upon adequate provocation. Should the court grant the instruction?
Late at night, an individual stood on a pedestrian overpass above an interstate highway and pushed a 45-pound concrete block off the ledge directly into the path of oncoming traffic moving at 70 miles per hour. The concrete block crashed through the windshield of an oncoming vehicle, killing the driver instantly. At trial, the prosecution presented undisputed evidence that the individual did not know the driver, had no specific desire to kill any particular motorist, and acted purely out of boredom. Of which homicide offense is the individual guilty under common law principles?
A defendant sneaked up quietly behind an unsuspecting pedestrian on an unlit sidewalk, raised a heavy steel pipe, and swung forcefully at the back of the pedestrian's head intending to fracture the pedestrian's skull. The pedestrian took a sudden step forward, and the pipe missed the pedestrian's head entirely by several inches. The pedestrian never saw, heard, or became aware of the defendant or the swinging pipe until police officers arrested the defendant moments later. Which offense did the defendant commit under common law principles?
