SUPERIOR COURT OF NEW JERSEY APPELLATE DIVISION DOCKET NO. A-2113-24

STATE OF NEW JERSEY,

Plaintiff-Respondent,

v.

ABAYUBA RIVAS,

Defendant-Appellant. __________________________

Argued January 13, 2026 – Decided February 25, 2026

Before Judges Sumners and Chase.

On appeal from an interlocutory order of the Superior Court of New Jersey, Law Division, Union County, Indictment No. 15-02-0114.

Scott M. Welfel, Assistant Deputy Public Defender, argued the cause for appellant (Jennifer N. Sellitti, Public Defender, attorney; Scott M. Welfel, of counsel and on the briefs).

Milton S. Leibowitz, Assistant Prosecutor, argued the cause for respondent (William A. Daniel, Union County Prosecutor, attorney; Michele C. Buckley, Assistant Prosecutor, of counsel and on the brief). PER CURIAM

Our Supreme Court reversed defendant Abayuba Rivas's conviction for

first-degree aggravated manslaughter and second-degree desecration of human

remains and related offenses 1 and ordered a new trial because his March 19,

2014 confession to killing his wife, Karla Villagra Garzon, should have been

suppressed. State v. Rivas, 251 N.J. 132, 138-39 (2022). Following remand,

the motion court dismissed defendant's motion to suppress other statements and

evidence of Karla's body as the fruit of a suppressed March 18 confession.

On leave to appeal granted, defendant argues: 2

POINT I

1 The related offenses were: fourth-degree unlawful possession of a weapon; third-degree possession of a weapon for an unlawful purpose; second-degree endangering the welfare of a child; third-degree hindering one's own apprehension by concealment or destruction of evidence; and two counts of third-degree hindering one's own apprehension by giving false information to law enforcement officers. 2 In seeking leave to appeal, defendant included his contention that the motion court erroneously denied his motion to suppress his February 27, 2014 statement. We granted leave to appeal to all contentions raised. However, because defendant did not address the suppression of his February 27, 2014 statement in his appeal merits brief it is deemed waived. See Petro v. Platkin, 472 N.J. Super. 536, 567 (App. Div. 2022); N.J. Dep't of Env't Prot. v. Alloway Twp., 438 N.J. Super. 501, 505 n.2 (App. Div. 2015) ("An issue that is not briefed is deemed waived upon appeal."); Pressler & Verniero, Current N.J. Court Rules, cmt. 5 on R. 2:6-2 (2026).

A-2113-24 2 THE MARCH 13TH STATEMENT SHOULD HAVE BEEN SUPPRESSED BECAUSE DEFENDANT DID NOT KNOWINGLY, INTELLIGENTLY, AND VOLUNTARILY WAIVE HIS MIRANDA[3] RIGHTS.

POINT II

[KARLA'S] BODY MUST BE SUPPRESSED AS FRUIT OF THE POISONOUS TREE OF THE ILLEGAL MARCH 18TH INTERROGATION.

A. UNITED STATES V. PATANE 4 DOES NOT FORECLOSE APPLICATION OF THE EXCLUSIONARY RULE TO SUPPRESS PHYSICAL EVIDENCE DISCOVERED PURSUANT TO A CONFESSION OBTAINED IN VIOLATION OF AN INVOCATION OF THE RIGHT TO COUNSEL.

B. THE STATE FAILED TO PROVE BY CLEAR AND CONVINCING EVIDENCE THAT [KARLA'S] BODY WOULD INEVITABLY HAVE BEEN DISCOVERED ABSENT [DEFENDANT'S] DISCLOSURE OF THE LOCATION DURING THE UNLAWFUL, NOW SUPPRESSED MARCH 18TH STATEMENT.

Having considered the parties' arguments, the record, and applicable law,

we affirm the motion court's order that evidence of Karla's body should not be

3 Miranda v. Arizona, 384 U.S. 436 (1966). 4 542 U.S. 630 (2004). A-2113-24 3 suppressed. However, we reverse the court's order declining to suppress

defendant's March 13 statement.

Circumstances Forming the Basis of Defendant's Appeal

A. Police Investigation

On February 24, 2014, defendant reported to the City of Elizabeth police

that his wife was missing and voluntarily appeared at the Elizabeth police station

on February 27 for an interview with police detectives. Without being read his

Miranda rights, defendant recounted the events leading up to his wife's death.

He stated that after his wife said she needed $300 for a CAT scan to address her

sinus problems, they got into a fight with her calling him "gay" and she left for

the pharmacy. Defendant authorized searches of his apartment, vehicles,

computer, cell phone, and agreed to provide a buccal swab and take a polygraph

examination on March 5.

A search of defendant's apartment led to seizure of a shirt with a stain of

Karla's blood and defendant's DNA. The search of defendant's car revealed

stains which, except for one of the samples matching Karla's DNA, were too

small to draw any forensic conclusions. A cadaver dog's hit identified the

A-2113-24 4 presence of human remains in the master bedroom, by a pair of brown work

boots, and in the car's front passenger seat, driver's seat, and rear cargo area .

On March 5, Elizabeth detectives interviewed defendant and administered

a polygraph test. Before administering the test, defendant was informed of his

Miranda rights, including that anything he said could be used against him in

court, and that he was entitled to an attorney if he could not afford one, among

other advisements. Defendant signed a written waiver of his Miranda rights.

During the test, defendant was asked if he killed his wife, the nature of his

relationship with Karla, and the circumstances of the crime. Defendant denied

killing her.

On March 6, the detectives learned that a police vehicle's license plate

reader (L.P.R.) had recorded defendant's license plate on Division Street in

Elizabeth in the early morning of February 24. After canvassing businesses on

Division Street, the police obtained two surveillance videos confirming that a

car consistent with defendant's car was on Division Street that early morning.

Consequently, the detectives asked to interview defendant on March 13,

at the Union County Child Advocacy Center. Defendant agreed and brought his

daughter. Detectives informed defendant that the purpose of the interview was

to address "some follow-up questions." Defendant claims the detectives told

A-2113-24 5 him the interview would last ten to fifteen minutes. The interview instead lasted

around eight-and-a-half hours, from 10:25 a.m. to 6:35 p.m.

Defendant was mirandized and waived his rights in writing. Throughout

the interview, defendant was provided with water and pizza and was permitted

to use the bathroom around 4:58 p.m. Detectives sat close to defendant at times

but did not threaten or physically assault him. Initially, defendant appeared

relaxed and spoke in a conversational tone. At one point, detectives repeatedly

told defendant that he failed the March 5 polygraph test and that they knew he

was lying. In addition, the detectives told defendant that his vehicle was seen

in a surveillance video the night his wife disappeared. Defendant then admitted

that he left the house that evening without his daughter "for a while." Defendant
