Rule of Law:
A trial court must instruct the jury on a lesser-included offense, such as involuntary manslaughter, when there is substantial evidence from which a reasonable jury could conclude that the defendant committed the lesser offense but not the greater. Evidence of a victim's unknown, pre-existing vulnerability can support the inference that the defendant lacked the subjective awareness of a high probability of death required for implied malice murder.
Facts:
- Eddie Ray Smith, Jr. had previously undergone orthopedic surgery during which metal rods were inserted into his neck, compromising its strength and making him more susceptible to a neck injury.
- Tyshaun Vasquez, who was 19 and significantly larger than Smith, and a companion named Jordan E., encountered the 43-year-old Smith in a park.
- Vasquez and Jordan approached Smith, grabbed him, and Vasquez went through Smith's pockets.
- Vasquez and Jordan punched Smith approximately 15 times, knocking him to the ground.
- While Smith was on the ground, Vasquez stomped on his head and body about 20 times.
- An autopsy revealed the cause of death was a neck fracture in the C2-C3 vertebrae, directly adjacent to the pre-existing metal rods.
- The medical examiner testified that all of Smith's other injuries were nonlethal and that the metal rods could have acted as a fulcrum, contributing to the fatal break.
- The medical examiner also noted Smith did not have other serious head injuries one might expect from a severe beating, such as a fractured skull, tooth damage, or brain bruises.
Procedural Posture:
- Tyshaun Vasquez was charged in a California superior court (trial court) with first-degree murder with a special circumstance and attempted second-degree robbery.
- During the jury trial, defense counsel requested an instruction on the lesser-included offense of involuntary manslaughter.
- The trial court denied the defense's request for an involuntary manslaughter instruction but agreed to instruct on second-degree murder.
- The jury convicted Vasquez of second-degree murder but acquitted him of first-degree murder, attempted robbery, and found the special-circumstance allegation not true.
- Vasquez filed a motion for a new trial, arguing the court erred by refusing the involuntary manslaughter instruction, which the trial court denied.
- The trial court sentenced Vasquez to a term of 15 years to life in state prison.
- Vasquez (appellant) appealed the conviction to the California Court of Appeal, Second District (the court issuing this opinion).

Issue:
Does a trial court commit prejudicial error by refusing to instruct the jury on the lesser-included offense of involuntary manslaughter when evidence, such as the victim's hidden and uniquely fragile neck condition, could allow a reasonable jury to find the defendant lacked the subjective awareness that his actions were likely to cause death?
Opinions:
Majority - Lavin, J.
Yes, the trial court committed prejudicial error by refusing to give the requested instruction. An instruction on a lesser-included offense is required whenever there is substantial evidence that the defendant acted without the mental state required for the greater offense. Involuntary manslaughter is an unlawful killing without malice, and implied malice for murder requires a defendant's subjective awareness that their conduct carries a high probability of death. Here, substantial evidence supported the defense theory that Vasquez lacked this subjective awareness. The medical examiner's testimony that most of Smith's injuries were nonlethal, combined with the fact that the fatal break occurred due to Smith's unknown and unique pre-existing neck vulnerability, could lead a reasonable juror to conclude Vasquez's beating was not so wanton and brutal as to demonstrate a conscious disregard for human life. The error was prejudicial because it denied Vasquez his primary defense, forcing the jury into an all-or-nothing choice between second-degree murder and acquittal—an implausible option given that Vasquez undoubtedly killed Smith. The jury's acquittal on all other charges indicates it already had doubts about the prosecution's theory and Vasquez's mental state.
Analysis:
This case strongly reaffirms the trial court's duty to instruct on lesser-included offenses when any substantial evidence supports them, even if that evidence seems unconvincing. It clarifies that evidence of a victim's hidden vulnerability (an 'eggshell skull' scenario) can be used not just to establish causation but also to negate the defendant's mental state for a higher charge like murder. The decision emphasizes that determining a defendant's subjective awareness is a quintessential jury function that judges must not usurp by weighing the evidence. For future cases, this precedent strengthens the defense's ability to argue for lesser charges based on a lack of subjective awareness, especially in assault cases with unexpected fatal outcomes.
