New Jersey Supreme Court Rules That Cell Site Location Evidence Requires an Expert Witness

Published on: April 24, 2026 | by Stephen J. Natoli

Cell-Phone-Tower-Expert-300x300 On April 16, 2026, the New Jersey Supreme Court issued a unanimous decision in State v. Jule Hannah that carries significant consequences for how cell phone location evidence can be presented in criminal trials. The Court held that cell site location information, commonly known as CSLI, involves technical and specialized knowledge that is beyond the understanding of the average juror, and therefore must be introduced through a qualified expert witness. The decision affirms the Appellate Division’s reversal of Hannah’s first-degree murder conviction and orders a new trial, drawing a clear line that prosecutors and defense attorneys across New Jersey must now respect.

The case arose from the January 2017 death of Miguel Lopez, who was found shot to death in his car in Bridgeton after crashing into a tree. Investigators developed Hannah as a suspect based on surveillance footage, DNA from a cigar butt recovered from the passenger seat, and cell phone records. At trial, the State sought to use those records to place Hannah in Lopez’s car during the ride from Monroe Township to Bridgeton. Rather than calling a qualified expert, the State presented Detective Sergeant Leyman as a lay witness to testify about which cell towers Hannah’s phone connected to during the relevant time period. The trial court tried to thread the needle allowing Leyman to testify about tower locations while repeatedly instructing the jury that a cell phone’s connection to a tower does not establish where the phone was at any given moment. That tension, the Supreme Court concluded, was precisely the problem.

The Court’s analysis began with a foundational distinction in the rules of evidence between lay and expert testimony. Under New Jersey law, a lay witness can offer opinions based on common knowledge and observation. When a subject is so technical that the average juror cannot form a valid conclusion without guidance, however, expert testimony is required. CSLI, the Court explained, squarely falls into that category. Whether a phone connects to the nearest tower depends not just on proximity but on a constellation of variables such as tower height, antenna direction, terrain and topography, network load balancing, and the technical characteristics of the phone itself. A jury left to draw inferences from raw call records, without any expert framework to interpret them, risks attributing far more or far less weight to that data than the evidence actually warrants.

New Jersey’s Three Strikes Law and Juvenile Offenses

Published on: April 15, 2022 | by Stephen J. Natoli

Jersey-City-Three-Strikes-Attorney-300x197 Three Strikes Laws were adopted in certain jurisdictions to protect the public from habitual offenders who repeatedly commit certain violent crimes. These law typically mandate a sentence of life imprisonment without parole for a third-time offender.

In New Jersey, the crimes that constitute “strikes” include those such as murder, manslaughter, aggravated assault, kidnapping, sexual assault and robbery.

But should crimes committed as juveniles be considered predicate offenses under the rule?

Criminal Sentencing Considerations: State v. Cynthia Rivera

Published on: February 18, 2022 | by Stephen J. Natoli

Sentencing Courts must carefully consider all aggravating and mitigating factors.

Following a criminal defendant’s conviction or guilty plea, a judge decides the appropriate punishment at sentencing. A sentence may include incarceration, probation, fines, restitution, community service and participation in rehabilitation programs. However, there may be instances where a judge is able to enhance or reduce a sentence based upon factors specific to the defendant and the crime committed.

Factors that indicate higher culpability, and may result in a harsher sentence, are known as “aggravating” factors. Examples of aggravating factors are: previous convictions, attempts to conceal or dispose of evidence, use of a weapon, targeting vulnerable victims, etc.

Statutory Requirements for Compassionate Release in New Jersey

Published on: September 10, 2021 | by Stephen J. Natoli

A petition for compassionate release is typically granted to inmates who suffer from a terminal illness or profound incapacity that renders them physically incapable of committing a crime in the future.

In New Jersey, there are specific requirements that must be met prior to a court’s consideration for compassionate release. First, an inmate must present a Certificate of Eligibility from the Corrections Department indicating that two department-designated physicians have determined that the inmate suffers from a terminal condition or permanent physical incapacity that did not exist at the time of sentencing.

After such a certificate is presented, the court may grant compassionate release but only if the court has found, by clear and convincing evidence, that the inmate is physically incapable of committing future crimes and that they pose no threat to public safety.

Supreme Court Deals with IEC Claim in Jersey City Homicide Case

Published on: August 30, 2021 | by Stephen J. Natoli

Ineffective assistance of counsel is a claim that a criminal defendant may assert when their defense attorney’s inadequate representation constitutes a violation of their Sixth Amendment right to counsel.

However, not all cases concerning an attorney’s unsatisfactory performance entitle a defendant to relief. The 1984 landmark Supreme Court case of Strickland v. Washington outlined the two requirements for proving ineffective assistance of counsel: (1) counsel’s performance must be deficient under the circumstances, and (2) but for the counsel’s deficient performance, there is a reasonable probability that the outcome of the case would have been different.

Since inadequate representation creates unfair disadvantages to defendants, and often wrongful convictions, successful ineffective assistance of counsel claims may allow for an overturned conviction, vacated sentence or even a new trial.
