Huntington Station Man Sentenced for Fatal DWI Crash

A Huntington Station man has been sentenced to four to 12 years for crashing into another vehicle while he was intoxicated, resulting in the death of his passenger.

Leo Flores-Gracias, 26, of Huntington Station, was sentenced to 4 to 12 years in  prison after pleading guilty to Aggravated Vehicular Homicide and other related charges, for  driving while intoxicated and crashing head-on into another vehicle, killing his own passenger,  Marlon Nunez-Cuellar, 25, of Huntington Station.  

On July 4, 2023, at approximately 8:06 p.m., Flores-Gracias and three others left a party where he had  been drinking alcohol. All four individuals got into Flores-Gracias’ 2017 Honda Accord. Flores Gracias began driving northbound on Sweet Hollow Road in Huntington and crashed head-on into  a vehicle that was driving southbound.  

An extraction of the vehicle’s event data recorder revealed that Flores-Gracias was traveling 72 miles per hour just one second before the impact, on a roadway where the posted speed limit is 30 mph.  

Marlon Nunez-Cuellar, one of Flores-Gracias’ passengers, was transported to Plainview Hospital, where he was pronounced dead from injuries he sustained in the crash.  

When police officers arrived at the scene, they observed Flores-Gracias exhibiting signs of  intoxication and placed him under arrest. Flores-Gracias consented to a blood draw upon request by police. Subsequent toxicology testing of his blood revealed that Flores-Gracias’ blood alcohol concentration (BAC) was .14%. Additionally, a sample of Flores-Gracias’ blood taken by hospital staff was also seized pursuant to a search warrant. Toxicology testing of that blood sample, taken at a different time than the sample taken by police, revealed Flores-Gracias’ BAC was .19%, more than two times the legal limit. While executing a search warrant of Flores-Gracias’ vehicle, law  enforcement found an open 12-pack of beer containing one remaining full bottle in the trunk. 

On June 6, 2024, Flores-Gracias pleaded guilty to the following charges before Supreme Court Justice Richard Ambro: 

  • aggravated vehicular homicide, a Class B felony
  • second-degree manslaughter, a Class C felony
  • aggravated driving while intoxicated, an Unclassified misdemeanor
  • reckless driving, an Unclassified misdemeanor  

On September 30, 2024, Ambro sentenced Flores Gracias to four to 12 years in prison.

“This defendant was under the influence of alcohol and made the choice to drive himself and his  friends home from a party. That selfish disregard for the safety of others lead to the tragic death of  his own friend, Marlon Nunez-Cuellar,” said Suffolk County District Attorney Ray Tierney. “We hope that the sentence  imposed today provides comfort to the victim’s family who have been dealing with the devastating  impacts of this defendant’s actions and serves as a reminder not to jeopardize the lives of others  by choosing to drive under the influence.”
