Incident location, Long Island
What Happened
A 58-year-old Hempstead man was arrested Saturday night following a Nassau County police investigation into a fatal overdose, according to News 12 Long Island. The suspect, identified as Nathaniel Greene, was taken into custody after investigators linked him to a death that Nassau County authorities are treating as a drug-related fatality.
According to News 12 Long Island, the arrest of Greene came on Saturday night, with the report published early Sunday morning on May 17, 2026. Nassau County police launched an investigation following the fatal overdose of a Nassau County resident, whose identity has not been publicly released by authorities at this time. The victim’s name is being withheld, though police confirmed the deceased was a Nassau County resident.
In the course of the police investigation, Greene was allegedly found in possession of a white powdery substance that law enforcement believes to be cocaine, as News 12 Long Island reported. The discovery of the alleged controlled substance played a central role in the criminal charges that Nassau County police subsequently filed against the 58-year-old Hempstead resident. Authorities have not publicly specified the precise location or circumstances under which Greene was found with the substance, nor have they confirmed the exact address where the fatal overdose occurred.
Greene now faces two serious drug-related criminal charges stemming from the investigation. According to Nassau County police, he has been charged with criminal sale of a controlled substance and criminal possession of a controlled substance. The dual charges reflect the scope of the investigation — not only was Greene allegedly found with the substance, but investigators believe he was involved in the sale of drugs that may have contributed directly to the victim’s death. No additional suspects have been publicly identified in connection with the case at this time.
The victim’s name remains withheld pending notification of next of kin, a standard practice in Nassau County fatality investigations. Nassau County police have not yet released further details about where the overdose took place, what specific substance caused the fatal overdose, or how investigators first connected Greene to the incident. The investigation is believed to be ongoing as of the time of initial reporting.
Location & Road Context
Hempstead is one of Nassau County’s most densely populated communities, situated in the southwestern portion of Long Island’s Nassau County. The town and village of Hempstead sit at a major crossroads of Long Island’s road network, with key thoroughfares including Hempstead Turnpike, Peninsula Boulevard, and Fulton Avenue running through or near the area — making it a heavily trafficked and active community. While the precise location of the overdose and arrest has not been specified by Nassau County police, Hempstead has historically seen a range of public safety incidents tied to its dense residential and commercial corridors.
Our database currently reflects 1 recorded incident in connection with this developing case. Nassau County encompasses a broad stretch of western Long Island, and law enforcement agencies there — including the Nassau County Police Department — routinely investigate drug-related fatalities as potential criminal matters when a sale of a controlled substance is suspected to have contributed to a death.
Investigation & Legal Proceedings
Nathaniel Greene, 58, of Hempstead, faces charges of criminal sale of a controlled substance and criminal possession of a controlled substance, according to Nassau County police as reported by News 12 Long Island. These charges in New York State can carry significant penalties depending on the weight and type of substance involved, the degree of the charge, and whether prosecutors pursue an elevated charge tied to a drug-sale death. Under New York Penal Law, criminal sale of a controlled substance in the first degree — the most serious classification — is a Class A-I felony and can carry a sentence of up to 20 years to life in prison, though the specific degree of the charges against Greene has not yet been publicly confirmed.
No information regarding arraignment date, bail status, or legal representation for Greene had been released as of the initial publication of this report. The Nassau County District Attorney’s office has not issued a separate statement at the time of this writing. The investigation into the overdose death itself — including the precise cause of death and the identification of the victim — remains active, and additional charges or arrests have not been ruled out by authorities.
Broader Impact
Fatal drug overdoses tied to criminal sale charges have become an increasing focus for Nassau County prosecutors in recent years, with law enforcement agencies pursuing “drug-induced homicide” theories in cases where a dealer is believed to have directly provided the substance that caused a death. While Greene faces criminal sale and possession charges at this stage, it is notable that New York law allows prosecutors to escalate charges when a sale of a controlled substance results in a fatality — a legal avenue that could come into play as this investigation develops and the medical examiner’s findings regarding the victim’s cause of death are finalized.
