State v. Barnes, 226 N.C. App. 318

Cardwell died at his home after defendant allegedly sold him methadone the previous night.
Dr. Jordan, the local medical examiner, determined death resulted from methadone toxicity based on autopsy and toxicology results.
Defendant was charged with second-degree murder and later trial included testimony about the toxicology report.
The State sought to call Brown and Dr. Winecker to elucidate the toxicology findings; defendant argued lack of notice under § 15A-903 and Sixth Amendment rights.
The trial court allowed Brown and Winecker to testify after voir dire; Brown testified about methadone in Cardwell’s blood and absence of Xanax.
Jury convicted defendant of involuntary manslaughter; trial court sentenced him to 21–26 months.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Confrontation right and expert testimony	Cardwell’s death opinion rested on testing and report.	Dr. Jordan’s opinion violated confrontation rights by relying on others’ reports.	No Sixth Amendment violation; cure by cross-examination.
Notice and discovery for toxicology witnesses	Brown and Winecker testimony necessary to clarify toxicology; proper under discovery rules.	Lacked reasonable notice; discovery violation under § 15A-903.	No abuse of discretion; discovery and notice not violated.
Effective assistance and strategic trial prep	Counsel had adequate opportunity to investigate and cross-examine.	Insufficient time to prepare due to late disclosure.	No reversible error; ample preparation time shown.
Jury instructions on involuntary manslaughter	Evidence permitted lesser-included offense instruction.	No basis for involuntary manslaughter given intent to sell.	Correctly charged; malice distinguishes second-degree murder from involuntary manslaughter.
