What Happened
A Hauppauge man pleaded guilty Wednesday to aggravated vehicular homicide and a sweeping list of additional charges after admitting he was drunk when he ran a red light at more than twice the posted speed limit, killing a Nassau County police officer on her way to work in Saint James earlier this year, according to Patch.
Matthew Smith, 21, of Hauppauge, was behind the wheel of a Chevrolet Silverado pickup truck when he drove through a red light on northbound Alexander Avenue in Saint James at approximately 70 miles per hour — more than double the road’s posted 30 mph speed limit — and struck the vehicle of Nassau County Police Officer Patricia Espinosa, Suffolk County prosecutors said. The crash occurred at approximately 6:07 a.m. on Friday, January 31, 2026. Espinosa was driving to work at the time of the collision.
Officer Espinosa was transported to Stony Brook University Hospital following the crash, where she was pronounced dead. Smith’s passenger, who has not been publicly named, was also transported to Stony Brook University Hospital, where he was treated for serious injuries including pelvic and spinal fractures and a severe head laceration, according to Patch’s report on the guilty plea.
According to court documents and Smith’s own admissions during the guilty plea proceeding, he and his passenger had left Jake’s 58 Casino Hotel in Smith’s Silverado at approximately 6:07 a.m. on January 31. Prosecutors noted that before arriving at the casino, Smith had been in Patchogue drinking alcohol. A chemical test of Smith’s blood following the crash revealed a blood alcohol concentration of .20 — more than twice New York’s legal limit of .08. Investigators also found a bottle of Bacardi rum and a shot glass inside Smith’s pickup truck, further underlining the degree of intoxication involved, Suffolk County prosecutors stated.
Smith entered his guilty plea Wednesday, June 11, 2026, before Supreme Court Justice Timothy Mazzei in Riverhead. The charges to which he admitted guilt were extensive: two counts of aggravated vehicular homicide, vehicular manslaughter in the first degree, second-degree manslaughter, aggravated vehicular assault, second-degree assault, vehicular assault, aggravated driving while intoxicated, driving while intoxicated, reckless endangerment, reckless driving, and multiple traffic infractions, per the Patch report citing the Suffolk County District Attorney’s Office. As part of the plea agreement, Smith also agreed to forfeit the Chevrolet Silverado pickup truck involved in the crash.
In a statement, prosecutors described the profound toll the crash took on Officer Espinosa’s family and department. “Patricia Espinosa, a wife and mother who dedicated her life to protecting others, was killed on her way to work, leaving her daughter without a mother, her husband without a wife, and a family without their beloved daughter and sister,” the District Attorney said. The DA added: “With today’s guilty plea, the defendant has admitted responsibility for causing her death, as well as for the injuries that he caused to his passenger. While nothing will restore what the victims and their families and colleagues have lost, we hope that this plea provides them with some measure of justice.”
Smith is represented by attorney Anthony LaPinta, who was not immediately available for comment at the time of the report. He is scheduled to return to court on July 20, 2026, for sentencing, at which point he is expected to receive a prison term of 7⅓ to 22 years.
Location & Road Context
The collision took place on Alexander Avenue in Saint James, a residential and mixed-use roadway in Suffolk County with a posted speed limit of 30 mph. At the time of the crash, Smith was traveling northbound when he blew through the red light intersection at roughly 70 mph — more than double the legal limit for that road. Saint James sits in the Town of Smithtown in central Suffolk County.

Investigation & Legal Proceedings
The case was prosecuted by the Suffolk County District Attorney’s Office and resolved with a guilty plea entered before Supreme Court Justice Timothy Mazzei in Riverhead on June 11, 2026. Smith’s plea covered the full breadth of charges arising from both Espinosa’s death and the serious injuries suffered by his passenger, encompassing homicide, manslaughter, assault, and DWI-related counts. As part of the negotiated agreement, Smith agreed to forfeit his Chevrolet Silverado and faces a sentencing range of 7⅓ to 22 years in state prison. His sentencing date is set for July 20, 2026. Defense attorney Anthony LaPinta had not responded to requests for comment as of the time of reporting, per Patch.

Broader Impact
Under New York State law, aggravated vehicular homicide — the top charge Smith admitted to — is a class B felony, carrying a maximum sentence of up to 25 years in state prison. Smith’s expected sentence of 7⅓ to 22 years reflects the seriousness with which New York courts treat DWI fatalities, particularly those involving first responders. A BAC of .20, combined with the presence of an open alcohol container and a shot glass in the vehicle, placed this incident well beyond a borderline impairment case, and the forfeiture of the vehicle as part of the plea is consistent with New York’s expanded use of asset forfeiture in serious DWI prosecutions.
