Samantha Bonora Case: Crash, Charges, and Cell Phone Ruling

The Samantha Bonora case is a pending Monmouth County, New Jersey prosecution in which Bonora, a Howell woman, faces first-degree aggravated manslaughter and other charges after a January 13, 2024 head-on crash on Route 34 that killed three-year-old Kylie Williams. In August 2025, a state appellate court threw out a search warrant that had authorized prosecutors to extract four years of data from Bonora’s cell phone, ruling the warrant unconstitutionally overbroad and casting doubt on the state’s ability to sustain the top charge.¹

The Crash on Route 34

On the afternoon of January 13, 2024, Bonora was driving a 2014 Dodge Ram pickup southbound on Route 34 near the Route 33 interchange in Howell Township. According to the Monmouth County Prosecutor’s Office, she tried to pass another vehicle at high speed, crossed into the northbound lanes, and collided head-on with a 2021 Jeep Grand Cherokee carrying four members of the Williams family. A third vehicle, a 2021 Ford Bronco, was also involved.¹²

Kylie Williams was pronounced dead at the scene. Her mother, Joelle Williams, who was driving the Jeep, sustained significant injuries and required multiple surgeries. Kylie’s two-year-old brother, Lucas, and her aunt, Valerie, were also hurt, though their injuries were described as minor. Bonora herself sustained minor injuries.³⁴

The Charges Against Bonora

On April 12, 2024, a Monmouth County grand jury returned an indictment charging Bonora with one count of first-degree aggravated manslaughter, two counts of second-degree aggravated assault, and two counts of fourth-degree assault by auto. She also received motor vehicle summonses for driving while intoxicated, speeding, improper passing, failure to maintain her lane, and driving with an expired license.¹ The case is docketed in Monmouth County Superior Court as Indictment No. 24-04-0392. Bonora has been held in jail since the crash.⁵

The top count is what makes the case unusual. Aggravated manslaughter in New Jersey is a first-degree crime carrying ten to thirty years in prison, and it requires the state to prove that the defendant acted recklessly with extreme indifference to human life. Second-degree vehicular homicide, which the defense argues is the appropriate charge, carries a significantly lower sentencing range.

What Investigators Found

Officers at the scene described Bonora as appearing impaired, noting drooping eyes and slurred speech. A blood sample drawn roughly three hours after the crash returned a mix of substances: methadone, EDDP (a methadone metabolite), morphine, free morphine, fentanyl, norfentanyl, lamotrigine, and xylazine, an animal tranquilizer that has appeared in the illicit drug supply.¹⁶

Bonora was prescribed 95 milligrams of methadone daily for opioid use disorder, and a labeled bottle of her methadone was recovered from the wrecked pickup. Investigators also seized two GPS units from the truck.¹

Records disclosed during the appellate proceedings show Bonora had prior convictions for driving while intoxicated in 2010 and 2015, along with a 2015 conviction for refusing a breathalyzer. She was arrested for possession of controlled dangerous substances in 2020 and again in 2022, and she was driving with an expired license on the day of the crash.⁶¹

The Appellate Ruling on Her Cell Phone

Prosecutors sought a comprehensive forensic extraction of Bonora’s cell phone covering January 1, 2020 through the day of the crash. The warrant authorized seizure of call logs, text messages, GPS data, emails, photos, videos, internet history, and deleted files. The state acknowledged that the four-year start date matched Bonora’s first drug possession arrest, and it leaned on a statement from an unnamed forensic toxicologist that it would be “useful to learn the extent of the person’s history with narcotic substances.”¹

A trial court denied Bonora’s motion to suppress in October 2024. Her attorney, Steven E. Nelson of Nelson, Fromer, Crocco & Jordan, petitioned the New Jersey Supreme Court, which directed the Appellate Division to hear the appeal.

On August 19, 2025, the Appellate Division reversed and held the warrant constitutionally invalid on two independent grounds. Probable cause was lacking, the court found, because reconstructing a defendant’s years-long drug consumption history through her phone was “doubtful at best” as a foundation for a search and amounted to an unreasonable intrusion into her “most private thoughts and communications.” The warrant was also overbroad in its four-year timeframe and in language that authorized a search for evidence of “violation of any of our state’s criminal laws,” rather than being confined to the offenses actually charged.¹

The court anchored its analysis in the Fourth Amendment and Article I, Paragraph 7 of the New Jersey Constitution, citing the U.S. Supreme Court’s decisions in Riley v. California and Carpenter v. United States, and the New Jersey Appellate Division’s 2023 ruling in State v. Missak, which held that cell phone warrants must be limited to specific data categories and time periods supported by probable cause.⁷ The court added that, to the extent Bonora’s drug-use history was relevant, prosecutors already had a more reliable source: her substance abuse treatment records, which they had obtained.¹

What the Ruling Means for the Prosecution

Nelson said the ruling would have a “significant and direct impact” on the aggravated manslaughter count and argued the case should be prosecuted as second-degree vehicular homicide. He accused investigators and prosecutors of being “driven by emotions” because of Kylie’s age and called the legal basis for the warrant “faulty.”⁵

The stakes are real. The state’s theory for first-degree aggravated manslaughter turns on proving extreme indifference to human life, a mental state prosecutors had hoped to establish in part by using the phone to document a long pattern of substance use. With that avenue closed, the case now rests on the toxicology results, the physical evidence recovered from the truck, officer observations of impairment at the scene, and Bonora’s treatment records.

Where the Case Stands

Monmouth County Prosecutor Raymond S. Santiago has said his office intends to appeal the Appellate Division’s ruling to the New Jersey Supreme Court. As of the appellate decision, the Supreme Court had not yet acted on that petition, and no trial date had been set. Bonora remains in custody in Monmouth County.⁵
