Grading the Offenses
The awareness line that separates reckless manslaughter from negligent homicide carries straight through to punishment, because the Code attaches a different felony grade to each offense. Manslaughter is a felony of the second degree under § 210.3(2), and negligent homicide is a felony of the third degree under § 210.4(2).1 Murder sits one step above both as a felony of the first degree, so the three homicide offenses occupy three consecutive grades.2 The grade then fixes the sentencing exposure: a second-degree felony carries a maximum of ten years in prison, and a third-degree felony carries a maximum of five.3
The grade falls with the mental state because punishment is meant to follow blameworthiness. A defendant who consciously disregards a risk of death has seen the danger and decided to run it, which is a choice made against the life at stake. A defendant who fails to perceive the same danger has made no such choice, and the fault lies in an inattention that a reasonable person would have avoided. Since the first defendant's culpability is greater, the Code ranks that offense one grade higher, yet it still treats the inadvertent killer as a felon, because the failure to perceive must itself be a gross deviation from reasonable care.4
The pair isolates awareness because everything else is held constant. Both drivers caused a death, both created a risk of the kind the Code calls substantial and unjustifiable, and both fell far below the standard the law expects. The grade drops by exactly one step, and no further, because the second driver still committed a criminal homicide. A failure to perceive a grossly unreasonable risk remains criminal negligence, although it is the lesser form of fault.
The lower grade for negligence also does practical work in the courtroom. Jurors asked to label a careless driver a manslaughterer often hesitate, reasoning that they might have made the same lapse themselves, and a jury that will not convict at a high grade may acquit outright. Some states created separate lesser homicide offenses for this reason, beginning with highway deaths.7 A proportionate offense gives the prosecution a charge the jury will accept, so that the careless killer is convicted of something that matches the fault instead of walking free.
The Code's pairing of a second-degree felony with a third-degree felony is one legislative choice among several. Ohio's separate offense of reckless homicide is a felony of the third degree, the same grade the Code gives negligent homicide, while Ohio's negligent homicide is a misdemeanor of the first degree and applies only when the death is caused by a deadly weapon or dangerous ordnance.8 Pennsylvania draws no grading line on awareness at all. Its involuntary manslaughter covers a death caused by an act done recklessly or with gross negligence, and the offense is ordinarily a misdemeanor of the first degree, rising to a felony of the second degree only when the victim is under twelve and in the defendant's care, custody, or control.9
These statutes show that the same facts can carry different grades in different jurisdictions. An answer goes wrong when it assigns the Code's grades to a state that grades differently, as when it calls a negligent killing a third-degree felony in a state that makes it a misdemeanor. The first question is which statute governs. Under the Code, the next question is whether the defendant was aware of the risk, because that fact alone moves a conviction between the second-degree and the third-degree grade.
