298 A.3d 1080
N.J.2023Background
- Dec. 25, 2015 armed home robbery; victims heard a phone announce an incoming call/text and heard clicking consistent with photos; they called 911 at ~8:15 p.m.
- Defendant’s cell phone records show a text received at 8:02 p.m. and several dark/blurry photos at 8:03 p.m.; photos of a “Princess” watch and web searches for that watch were on his phone in the days after the robbery.
- A Costco bag found in the stairwell after the robbery tested positive for defendant’s DNA; defendant had previously done brief contracting work at the victims’ residence.
- FBI Special Agent Ajit David testified as an expert that, based on a “rule of thumb” (his training/experience), the cell tower that received the 8:02 p.m. ping had approximately a one-mile radius and therefore covered the crime scene.
- Victim Rosette misidentified a filler photo the day after the robbery, declined to identify anyone two days later, then was told a suspect name and shown watch photos from defendant’s phone before making a first-time in-court identification at trial.
- The trial court admitted both the cell-site “one-mile” testimony and Rosette’s first-time in-court ID; defendant was convicted. The New Jersey Supreme Court held both admissions were erroneous and that their combined effect required reversal and a new trial; the State may not re-ask Rosette to identify defendant at retrial.
Issues
| Issue | State's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of cell-site expert testimony (one-mile "rule of thumb") | Agent’s training/CAST qualification and his maps suffice; cell-site analysis is generally accepted to place a phone in a general area. | The one-mile estimate was an unsupported "net opinion"—no tower measurements, drive-testing, propagation maps, or tower data were offered. | Reversed: the opinion was an improper net opinion under N.J.R.E. 702/703 because it rested solely on the expert’s personal experience without supporting data. |
| Admissibility of first-time in-court identification by Rosette | Rosette had prior brief contacts with defendant and jury could assess credibility; cross-examination and instructions cure suggestiveness. | Police tainted the identification (gave defendant’s name, said he was arrested, showed watch photos), and Rosette had earlier mis- and non-identifications; no "good reason" for in-court ID. | Reversed: the in-court ID was highly suggestive and there was no good reason to allow a first-time courtroom identification; it should have been excluded. |
| Disclosure and procedural safeguards for first-time in-court IDs | (Implicit) existing procedure/jury controls adequate. | Prosecutors must disclose trial-prep comments and complete photo-display forms; State should justify first-time in-court IDs in advance. | Court requires motion in limine for first-time IDs, disclosure under Rule 3:11 of trial-prep comments relating to ID, and completion of photo-display forms. |
| Cumulative-prejudice/harmless-error analysis | Any error was harmless given DNA on bag, watch photos on phone, phone activity matching victims’ testimony, and matching clothing. | The combination of the unreliable expert tower placement and the suggestive in-court ID was capable of affecting the verdict; prejudice requires new trial. | Reversed: the combined admission of both items was prejudicial and deprived defendant of a fair trial; convictions vacated and remanded for new trial. |
