Key Facts
- State level: Second-degree manslaughter has no single nationwide definition because states choose their own offense names, elements, classifications, and penalties.
- Washington state level: Washington defines second-degree manslaughter as causing another person’s death with criminal negligence and classifies it as a Class B felony.
- New York state level: New York’s principal second-degree manslaughter rule covers recklessly causing another person’s death and classifies the offense as a Class C felony.
- Oklahoma state level: Oklahoma uses second-degree manslaughter as a Class B5 residual homicide category involving an act, procurement, or culpable negligence when the killing is not murder, first-degree manslaughter, or excusable or justifiable homicide.
- State level: Minnesota illustrates that similar conduct can be called simply manslaughter in the second degree and can include several specifically listed forms of culpable negligence or risk creation.
- Federal level: The federal manslaughter statute uses voluntary and involuntary categories rather than first and second degrees.
- Federal and state: A conviction requires proof beyond a reasonable doubt of every fact necessary to constitute the charged crime.
Second-degree manslaughter is not a national offense with uniform elements. Its meaning comes from the law of the jurisdiction defining the charge. The statutes compared here show materially different designs: Washington uses criminal negligence, New York uses recklessness in its principal provision, Oklahoma uses a residual homicide category that includes culpable negligence, and Minnesota lists several specific theories.
What second-degree manslaughter means depends on the state
The word degree ranks an offense within a particular statutory system; it does not create a common definition shared by every state. The relevant offense provision identifies the prohibited result, required mental state, and any special routes to liability. Classification and sentencing rules may appear in that provision or in separate statutes, as the Washington, New York, Oklahoma, and Minnesota provisions illustrate.
This is also why a national answer to “what is second-degree manslaughter?” must be comparative. Washington uses criminal negligence, New York uses recklessness in its core provision, and Oklahoma uses a residual definition that expressly refers to culpable negligence. Minnesota lists several ways the offense can occur, including culpable-negligence risk creation and certain deaths involving animals, traps, or firearms.
Washington and New York use different mental states
Washington Revised Code section 9A.32.070 provides that a person commits manslaughter in the second degree by causing another person’s death with criminal negligence. The same provision classifies the offense as a Class B felony. Washington Revised Code section 9A.20.021 authorizes a maximum of ten years of confinement, a $20,000 fine, or both for a Class B felony.
New York Penal Law section 125.15 likewise begins with recklessly causing another person’s death. It also covers intentionally causing or aiding another person to commit suicide. New York classifies second-degree manslaughter as a Class C felony, showing why the complete statutory subsection matters more than a short dictionary definition.
Oklahoma uses a different statutory design
Oklahoma Statutes title 21, section 716 defines second-degree manslaughter as a Class B5 felony involving a killing caused by another person’s act, procurement, or culpable negligence that is not murder, first-degree manslaughter, or excusable or justifiable homicide. This residual structure asks where the killing fits after the code’s other homicide categories are considered.
Oklahoma’s section 722 confirms the Class B5 classification and supplies a separate penalty provision. It authorizes two to four years in the state penitentiary, up to one year in county jail, a fine of up to $1,000, or both fine and imprisonment. Those alternatives are specific to Oklahoma and cannot be used as a sentencing answer for a charge under another state’s law.
Minnesota shows how one degree can contain several theories
Minnesota Statutes section 609.205 calls its offense manslaughter in the second degree and lists multiple theories. They include causing death through culpable negligence by creating an unreasonable risk and consciously taking the chance of causing death or great bodily harm, as well as specified situations involving a dangerous animal, a spring gun or similar device, and negligent firearm or dangerous-weapon conduct.
Minnesota generally authorizes imprisonment for up to ten years, a fine of up to $20,000, or both for this offense. The list demonstrates that even when two states share the same offense name, their elements need not match.
Second-degree manslaughter is not the federal classification
Federal law does not divide manslaughter into first and second degrees. Instead, 18 U.S.C. section 1112 defines manslaughter as an unlawful killing without malice and separates it into voluntary manslaughter, involving a sudden quarrel or heat of passion, and involuntary manslaughter under the circumstances stated in the statute. The federal provision also operates within federal territorial or maritime jurisdiction, not as a general substitute for state homicide law.
A useful internal comparison is the broader manslaughter definition, while the distinction between second-degree murder and manslaughter turns on the elements adopted by the governing jurisdiction. Neither comparison can replace reading the actual charging provision.
The prosecution must prove the statutory elements
The offense label does not itself establish guilt. In In re Winship, the Supreme Court held that due process requires the prosecution to prove beyond a reasonable doubt every fact necessary to constitute the charged crime. In a second-degree manslaughter prosecution, the offense facts are defined by the applicable statute.
The compared statutes use different mental-state language. Washington requires criminal negligence, New York requires reckless causation in its principal provision, Oklahoma expressly refers to culpable negligence within its residual definition, and Minnesota describes culpable negligence through unreasonable risk creation and consciously taking a chance of causing death or great bodily harm.
A sentence cannot be predicted from the offense name
The contrast among Washington, Oklahoma, and Minnesota is concrete: Washington and Minnesota each state a ten-year maximum in the provisions cited here, while Oklahoma provides different custody and fine alternatives. New York uses its felony-classification and sentencing statutes. A phrase such as “second-degree manslaughter sentence” therefore has no reliable nationwide number.
