Defendant-Appellant.

Submitted January 7, 2026 – Decided April 17, 2026 Before Judges Mayer and Jacobs.

On appeal from the Superior Court of New Jersey, Law Division, Hunterdon County, Indictment No. 23-03-

0061.

Jennifer N. Sellitti, Public Defender, attorney for appellant (Stefan Van Jura, Assistant Deputy Public Defender, of counsel and on the brief).

PER CURIAM Defendant Brandon Petersen appeals his conviction for first-degree murder and related charges following a jury trial. We affirm.

I.

On December 6, 2020, defendant and a companion, Michele Carkhuff, arrived unannounced at Sarah Conrad's apartment in Delaware Township. The apartment was located within a farm estate. Conrad, friends with Carkhuff but unfamiliar with defendant, hesitated to admit them. Because Carkhuff complained of a toothache, Conrad allowed them inside so Carkhuff could rest. Carkhuff took medication and fell asleep on Conrad's couch.

While Carkhuff was sleeping, Conrad and defendant smoked marijuana.

Defendant also produced a water pipe or bong. Conrad would later tell police she and defendant had smoked marijuana and ingested psychoactive mushrooms. However, at trial, she testified she smoked marijuana but did not consume any mushrooms and did not see defendant do so.

After Carkhuff awoke, defendant and Conrad drank a few ounces of rum.

The trio then began cleaning the apartment and cooking dinner in the kitchen. Defendant offered to chop vegetables and asked for a knife. While chopping, he suddenly stabbed Carkhuff in the neck with the knife, striking her jugular

vein. A second stab penetrated Carkhuff's left eyebrow, fracturing her forehead bone. She also suffered knife wounds to her left hand, described at trial as defensive wounds. Despite her injuries, Carkhuff retreated to a bathroom, locking herself inside. Conrad managed to unlock the bathroom door and found Carkhuff on the floor, covered in blood.

Defendant attempted to flee in his vehicle, but it would not start. While defendant worked to start his vehicle, Conrad called her friend, Kate Gilmour, for help. Conrad then went outside to move her own pickup truck closer to the residence. As Conrad was moving the truck, defendant overpowered and pulled her out, then drove away in Conrad's truck. Conrad returned to the apartment to assist Carkhuff.

As Gilmour and her boyfriend, Peter Samuels, reached the estate, they encountered defendant exiting from the driveway. Defendant told Gilmour and Samuels that Carkhuff was back at the apartment and needed help, then drove away. Reaching the apartment, Gilmour and Samuels found Conrad with Carkhuff, whose breathing had become labored. With Gilmour and Conrad tending to Carkhuff in the back seat, Samuels drove to the hospital, where Carkhuff was pronounced dead.

In their investigation of Conrad's apartment, police observed signs of a struggle⸺food on the floor, a knife on the kitchen floor with blood on the blade, and blood droplets trailing to the bathroom. Police also located Conrad's pickup truck several miles away, abandoned with its keys inside. Following a tip from defendant's ex-fiancée, Pennsylvania State Police arrested defendant in the early morning of December 7 in Upper Black Eddy, Pennsylvania.

Hunterdon County Prosecutor's Office Detective Sergeants Aaron Lacey and Peter Pfeifer interviewed defendant at the Pennsylvania State Police barracks. After waiving his Miranda1 rights at approximately 10:20 a.m., defendant recounted his version of the events to police. He stated all three of the individuals originally in the apartment had consumed alcohol, smoked marijuana, and that Conrad and Carkhuff had snorted cocaine. He denied consuming mushrooms, the subject having been conveyed to police in their interview of Conrad. According to defendant, Conrad became angry and argued with Carkhuff. Although he did not see Conrad stab Carkhuff, he purportedly heard somebody say "Oh my f[***]ing God, why did you f[***]ing do that[?]" Then he "heard [Conrad] start f[***]ing screaming like she was talking to somebody, but there was nobody else in [the room]. I was in [another] room

and -- I don't know. Either she's yelling at herself for doing it or yelling at [Carkhuff] for making her do it. I don't know."

The detectives asked if defendant had ever been diagnosed with any mental illness. At first, defendant described having been diagnosed as having attention deficit disorder and attention deficit hyperactivity disorder. Lacey responded, "Well, that's a learning disability." When Lacey pointedly asked, defendant denied ever having been diagnosed with bipolar disorder or schizophrenia.

After being advised he faced extensive prison time if convicted, defendant then said, "I have antisocial disorder. I have bipolar disorder and borderline schizophrenia[,]" adding that although he had taken medications for those conditions in the past, he had not "taken any in a long time." At trial, Lacey testified defendant did not appear intoxicated or under the influence of drugs during the interrogation.

In July 2021, a grand jury returned an indictment charging defendant with first-degree murder, N.J.S.A. 2C:11-3(a)(1), (2) (count one); third-degree possession of a weapon (knife) for an unlawful purpose, N.J.S.A. 2C:39-4(d) (count two); fourth-degree unlawful possession of a weapon, N.J.S.A. 2C:39- 5(d) (count three); fourth-degree unlawful taking of means of conveyance,

N.J.S.A. 2C:20-10(b) (count four); and third-degree witness tampering, N.J.S.A. 2C:28-5(a)(1)-(5) (count five).

Trial took place over thirteen days in May 2023. Defendant pursued a third-party guilt defense, contending Conrad was the perpetrator. Conrad testified, denying culpability. The jury found defendant guilty of murder, weapons, and unlawful taking charges, acquitting him of witness tampering. The trial judge merged count two with count one for sentencing and imposed an aggregate term of sixty-years' imprisonment subject to an 85% period of parole ineligibility pursuant to the No Early Release Act, N.J.S.A. 2C:43-7.2. The judge imposed two concurrent eighteen-month terms for counts three and four to run concurrent to the sentence for count one.

Defendant timely appealed, raising three arguments:
