This appeal addresses whether the trial court erred by admitting into evidence a statement defendant had made to police and barring in part the testimony of defendant's expert witness.
Several months after the drug-induced death of the victim, a police detective interviewed defendant, eliciting from her information about her cell-phone usage before he advised her of her Miranda rights and information regarding her drug-selling activity and contact with the victim after he advised her of her rights. The detective told defendant he was "not holding anything back" and was "laying it all out . . . on the table" but never mentioned the death of the victim and repeatedly used the present tense when discussing her. Defendant confessed to selling heroin to the victim. The parties did not raise before the trial court the admissibility of defendant's statement, and the statement was admitted into evidence. The trial court granted the State's pretrial motion to bar defendant's expert witness from testifying about drug use and addiction, finding him qualified only in toxicology and not in those fields. A jury convicted defendant of committing a first-degree drug-induced death crime, in violation of N.J.S.A. 2C:35-9(a), along with other drug-related crimes.
The court finds the trial court (1) committed plain error by admitting defendant's statement without first conducting a Rule 104 hearing to determine under a totality-of-the-circumstances test the voluntariness of defendant's statement and Miranda waiver; (2) erred in admitting the pre-Miranda questions and answers but that that error did not rise to the level of plain error because other evidence was admitted regarding defendant's cell-phone usage; and (3) abused its discretion by limiting defendant's expert testimony without conducting a Rule 104 hearing regarding the expert witness's qualifications and opinions. The court remands the case and instructs the trial court to conduct evidentiary hearings regarding the voluntariness of defendant's statement, the qualifications of defendant's expert witness, and the admissibility of his opinions. Whether defendant's convictions are affirmed or vacated for a new trial depends on the outcomes of those hearings.
