Westbury Man Sentenced To 6 Years Jail Time After Pleading Guilty To Selling Heroin, Fentanyl And Coke: DA

MINEOLA, NY — A Westbury man is set to serve six years behind bars after pleading guilty to drug sale and weapons possession charges, prosecutors announced Friday.

Nassau County District Attorney Anne Donnelly announced Friday that 35-year-old Anthony Gianatiempo had been sentenced after pleading guilty to one count of criminal sale of a controlled substance and one count of attempted criminal possession of a weapon.

In addition to the jail time, Donnelly's office announced Gianatiempo would be under post-release supervision for five years once leaving prison.

Previously, Gianatiempo had been indicted on 32 counts including 11 counts of third-degree criminal possession of a controlled substance and nine counts of first-degree criminal possession of a weapon.

The charges, Donnelly's office said, stem from a June 18, 2025 drug transaction in Cantiague park. In that exchange, the man sold multiple bags containing alprazolam, cocaine, fentanyl, heroin and ketamine for a lump sum of $820, prosecutors said.

Also present in the bags he sold was xylazine, a veterinary tranquilizer that's sometimes referred to as "tranq," Donnelly's office said.

Subsequent to that drug deal, prosecutors said a search warrant was issued for and executed at Gianatiempo's home, with police arriving to arrest him and search the premises Aug. 5, 2025.

Upon arrival, prosecutors said police found 63 grams of heroin, 39 grams of fentanyl, 69 grams of methamphetamine, cocaine, ketamine, brown cardboard tubes with fuses wrapped in tape and a bottle wrapped in electrical tape with a fuse. Additionally, prosecutors said the police found counterfeit money and smokeless powder in the home.

"Along with the illegal narcotics found in the defendant's home, 15 grams of N-Pyrrolidino Isotonitazene, a nitazene compound that is a dangerous and powerful synthetic opioid, was recovered in a black handbag on the floor near the defendant's bedroom," Donnelly's office said.

Gianatiempo was arrested that day, prosecutors said.

"Inside Anthony Gianatiempo's basement was a dangerous collection of deadly drugs and hazardous explosives that had the potential to injure or kill Nassau County residents," Donnelly said. "We have worked with our law enforcement partners for years to end the opioid epidemic on Long Island and save lives. Putting criminals like Gianatiempo behind bars – who value profit above all else while they poison our communities – is a small victory in our continued fight. But that fight also requires decisive legislative action. I once again urge our legislators to revisit New York's drug laws and finally list xylazine and all nitazene compounds as scheduled controlled substances in the Public Health Law. Give us the tools to stop the spread of these substances in the illicit drug market and hold dealers accountable."
