Com. v. Sun, C., 268 A.3d 401

On July 12, 2019, Chengzao Sun and his wife Shu Yang argued during dinner; Sun chased Yang into the kitchen carrying an aluminum baseball bat and struck her on the back and leg.
Yang sustained fresh, swelling red bruises; photographs and her written police statement describing the attack were introduced at trial.
Sun admitted to an officer that he grabbed the bat and hit his wife after losing control.
A jury convicted Sun of aggravated assault (use of a deadly weapon), simple assault, and harassment; he was sentenced to 48 hours to 23 months’ incarceration plus probation.
On appeal Sun argued (1) the evidence was insufficient to show the bat was used as a "deadly weapon" and (2) the case should be remanded so trial counsel could explain why he did not object to the court’s failure to define "serious bodily injury."

Issue	Sun's Argument	Commonwealth's Argument	Held
Sufficiency of evidence that bat was a "deadly weapon" under 18 Pa.C.S. § 2702(a)(4)	Single strikes to back and leg do not establish use or intent to use the bat in a manner likely to cause death or serious bodily injury; therefore insufficient evidence of a "deadly weapon."	Jury could reasonably conclude the bat was used in a manner likely to produce serious bodily injury (struck back where spine/kidneys are vulnerable); a baseball bat can be a deadly weapon.	Affirmed. Viewing evidence in Commonwealth’s favor, use of the aluminum bat on the back supported finding it was used in a manner likely to produce serious bodily injury.
Request to remand for trial counsel testimony about failure to request jury instruction defining "serious bodily injury"	Counsel should testify to show a strategic reason for not objecting; remand needed to evaluate ineffective assistance claim.	Ineffectiveness claims ordinarily must await collateral (PCRA) review; no record-based, apparent ineffectiveness or waiver to allow direct review.	Denied. Claim not preserved for direct appeal and not appropriate for remand; defer to collateral review absent record-apparent ineffectiveness or waiver.
