New Jersey Appellate Division Rules on Drug-Induced Death Case

On April 9, 2024, the Superior Court of New Jersey, Appellate Division, delivered a pivotal decision in the case of State of New Jersey v. Shannon A. McGuigan. This case sheds light on critical procedural matters involving Miranda warnings and the use of expert testimony in drug-induced death cases in New Jersey.

Facts and Procedural Background Details of the McGuigan Case

Shannon A. McGuigan was convicted of causing a drug-induced death, among other charges, after she sold heroin, which led to a fatal overdose. The legal proceedings raised significant questions regarding the admissibility of her confession and the limitations placed on expert witness testimonies, which were pivotal aspects of her conviction appeal.

Legal Issues and Court’s Rationale Miranda Rights in the Context of Drug-Induced Death in New Jersey

The appellate court specifically addressed whether McGuigan’s waiver of her Miranda rights was voluntary, knowing, and intelligent, considering the interrogation methods used, which included not informing her of the victim’s death during questioning. The State, which had a duty to prove the knowing and voluntary nature of the defendant’s waiver, did not move to admit the statement, and the defendant did not move to exclude it.

The Court remanded the case with instructions the trial court engage in a totality-of-the-circumstances analysis after first conducting a Rule 104 hearing – the proper setting to develop the record regarding the State’s ability or inability to prove the voluntariness of the defendant’s statement.

Expert Testimony in New Jersey Drug-Induced Death Cases

The court also criticized the lower court’s handling of expert testimony, mainly how the trial judge had restricted the testimony of McGuigan’s expert, who was prepared to contest the cause of death and the victim’s drug usage patterns. The appellate court ruled that a hearing should have been conducted to assess the expert’s qualifications and the admissibility of his testimony.
