What Happened
Seven motorists were arrested overnight during a Fourth of July holiday sobriety checkpoint in Central Islip, Suffolk County, the Suffolk County Police Department announced on Saturday, July 4, 2026. According to Central Islip Daily Voice, the enforcement effort was part of a broader Independence Day crackdown targeting impaired drivers on Long Island, and 462 vehicles passed through the checkpoint during the operation.
Five of the seven arrested drivers were charged with Driving While Intoxicated (DWI). Those defendants, as identified by police and reported by Daily Voice, are:
- Williams Oberto, 49, of Central Islip
- Jose Molina, 56, of Brentwood
- Pedro Manuel Moncada Jimenez, 42, of Central Islip
- Edwin Edenilson Mena Guillen, 29, of Westbury
- Santiago Ariza Diaz, 22, of Central Islip
A sixth motorist, Ariel Estive Serrano Ochoa, 24, of Bay Shore, faced a separate charge: Driving While Ability Impaired by Drugs (DWAI-Drugs), according to police. A seventh driver, Gustavo Elias Henriquez Rojas, 28, of West Babylon, was charged with the more complex offense of Driving While Impaired by the Combined Influence of Drugs and Alcohol — a charge that reflects the simultaneous presence of both substances impairing a motorist’s ability to operate a vehicle.
All seven defendants were scheduled to be arraigned at First District Court in Central Islip on Saturday, July 4, 2026, police said. No injuries to other motorists or checkpoint personnel were reported in connection with any of the seven arrests.
Volunteers and staff from Mothers Against Drunk Driving (MADD) were also on hand during the checkpoint operation, assisting law enforcement by providing educational information to the hundreds of motorists who passed through. Out of the 462 vehicles that went through the checkpoint, seven drivers — roughly one in every 66 — were placed under arrest on impairment-related charges.
The enforcement action underscores an ongoing concern for Suffolk County law enforcement heading into the summer season, when holiday weekends historically correspond with elevated rates of impaired driving across Long Island’s roads. The July 4 holiday, in particular, is consistently one of the deadliest periods nationally for DWI-related incidents.
Location & Road Context
The checkpoint was conducted in Central Islip, a hamlet in the Town of Islip in central Suffolk County. Central Islip sits at a crossroads of major Long Island roadways, with access to the Long Island Expressway (I-495), Sunrise Highway (NY-27), and a network of county and local roads that see heavy recreational and commuter traffic during holiday weekends. The First District Court, where all seven defendants were scheduled for arraignment, is also located in Central Islip, making it the hub for Suffolk County’s western district criminal proceedings.
Impaired driving arrests in and around Central Islip and neighboring communities like Brentwood, Bay Shore, and West Babylon are not uncommon. The diversity of hometowns among those arrested — spanning from Westbury in Nassau County to West Babylon in western Suffolk — illustrates how broadly holiday checkpoint operations can net drivers traveling through a region.
Investigation & Legal Proceedings
All seven defendants face arraignment at First District Court in Central Islip, according to Daily Voice. The five charged with standard DWI — Oberto, Molina, Moncada Jimenez, Mena Guillen, and Ariza Diaz — face prosecution under New York Vehicle and Traffic Law §1192. Ariel Estive Serrano Ochoa faces charges under the DWAI-Drugs provision of that statute, while Gustavo Elias Henriquez Rojas faces the combined-influence charge, which can carry distinct evidentiary and sentencing considerations. No bail amounts were specified in the initial police announcement.
What This DWI Charge Means
New York Vehicle and Traffic Law §1192 establishes several tiers of impaired-driving offenses. A charge of Driving While Ability Impaired (DWAI) by alcohol covers drivers with a blood alcohol content (BAC) between 0.05% and 0.07%, while a standard DWI charge applies at 0.08% BAC or higher. Aggravated DWI — the most serious tier — applies when a driver’s BAC reaches 0.18% or above, or when a child under 16 is present in the vehicle. DWAI by Drugs, the charge faced by Ariel Estive Serrano Ochoa, applies when a driver is impaired by any drug other than alcohol; the combined-influence charge faced by Gustavo Elias Henriquez Rojas applies when both alcohol and drugs are present and contributing to impairment.
For a first-offense standard DWI in New York, penalties include fines ranging from $500 to $1,000, a mandatory minimum six-month license revocation, a potential jail sentence of up to one year, and a required ignition interlock device on any vehicle the convicted person owns or operates for at least six months. Repeat offenses escalate these consequences dramatically, potentially resulting in felony charges, multi-year license revocations, and state prison time. Drivers who refuse a chemical test — breathalyzer or blood draw — face an automatic one-year license revocation and a $500 civil penalty under New York’s implied consent law, regardless of the outcome of the criminal case.
Case Status & Updates
It is important to note that an arrest or criminal charge is an accusation, not a conviction. All seven individuals identified in this report — Williams Oberto, Jose Molina, Pedro Manuel Moncada Jimenez, Edwin Edenilson Mena Guillen, Santiago Ariza Diaz, Ariel Estive Serrano Ochoa, and Gustavo Elias Henriquez Rojas — are presumed innocent until and unless proven guilty in a court of law. Each was scheduled for arraignment at First District Court in Central Islip on July 4, 2026, where they will enter pleas and the court process will formally begin.
Long Island Traffic tracks DWI and DWAI cases through the Suffolk County and Nassau County court systems and updates each report as arraignment outcomes, plea agreements, and sentencing decisions become part of the public record.

Broader Impact
The scale of this single checkpoint operation — seven arrests out of 462 vehicles, spanning DWI, DWAI-Drugs, and combined-influence charges, with defendants drawn from six different Long Island communities — reflects the wide reach that holiday enforcement efforts can have. MADD’s participation in the checkpoint, providing educational materials directly to motorists as they passed through, adds a public-awareness dimension that goes beyond arrests alone.
