Incident location, Long Island
What Happened
A Cedarhurst man has been arrested and charged with manslaughter more than two months after a fatal two-vehicle crash on Branch Boulevard in Woodmere, Nassau County — a collision that claimed the life of a Valley Stream man who lingered in critical condition before succumbing to his injuries. According to a report by News 12 Long Island, Brayan Romero Flores, 24, was taken into custody in connection with the March 19, 2026 incident, with the arrest coming on or around May 29, 2026 — roughly 71 days after the crash itself.
Nassau County police say that at approximately 8 a.m. on that Thursday morning, Michael Kreindler, 39, of Valley Stream, was behind the wheel of a 2023 Tesla traveling on Branch Boulevard in Woodmere when his vehicle collided with a 2019 Honda Accord being driven by Romero Flores. The precise mechanics of the collision — including direction of travel, speed, or which vehicle may have been at fault in the initial impact — were not specified in the police account reported by News 12 Long Island, but the severity of the crash was immediately apparent.
Kreindler was transported from the scene in critical condition and rushed to a hospital for treatment. Despite medical intervention, he did not survive — dying from injuries sustained in the crash. His death elevated the incident from a serious injury collision to a fatal one, and it was the determination of his cause of death that ultimately paved the way for the felony charges now facing Romero Flores.
Romero Flores himself was not immediately arrested in the aftermath of the March 19 crash. Nassau County investigators spent the following weeks building their case, a process that commonly involves forensic reconstruction of the crash scene, review of surveillance footage, analysis of vehicle data and black box information, coordination with the medical examiner’s office to confirm cause of death, and legal consultation on the appropriate charges. The arrest, when it came, carried serious weight: Romero Flores was charged with manslaughter, criminally negligent homicide, assault, and reckless driving, according to Nassau police as reported by News 12 Long Island.
Romero Flores was arraigned following his arrest, where he entered a plea of not guilty to all charges. The judge overseeing the arraignment ordered him remanded — held without bail — reflecting the seriousness of the charges and the circumstances of the case. As of the time of the arrest report, he remained in custody.
The victim, Michael Kreindler, was 39 years old and a resident of Valley Stream, a hamlet in Nassau County located just a short distance from the Woodmere crash site. He had been driving a relatively new 2023 Tesla at the time of the collision. Kreindler leaves behind a community still processing the loss of a neighbor and the delayed nature of the justice process that followed his death.
Location & Road Context
Branch Boulevard in Woodmere is a surface-level roadway running through a densely populated residential and commercial area of the Five Towns region of Nassau County. The Five Towns area — which includes Woodmere, Cedarhurst (where Romero Flores resides), Lawrence, Hewlett, and Inwood — features a network of local roads that see heavy commuter and commercial traffic, particularly during morning rush hours. A crash at 8 a.m. on a Thursday places the incident squarely within peak morning travel time, when Branch Boulevard would typically be carrying residents heading toward major arteries including the Belt Parkway and the Southern State Parkway.
Woodmere has seen other serious accidents in recent months. A related update to a fatal vehicular incident in the area was reported as recently as June 1, 2026, underscoring the continued traffic safety concerns along these local Nassau County corridors.
Investigation & Legal Proceedings
The charges filed against Romero Flores are significant in scope and carry serious potential penalties under New York State law. Manslaughter in the second degree — the charge most commonly applied in vehicular fatality cases involving reckless or criminally negligent driving — is a Class C felony in New York, carrying a potential sentence of up to 15 years in state prison. Criminally negligent homicide is a Class E felony, while the assault and reckless driving charges add additional layers of criminal liability. Nassau County prosecutors will now need to prove at trial — should the case proceed that far — that Romero Flores’ conduct behind the wheel rose to the level of criminal negligence or recklessness sufficient to establish legal culpability for Kreindler’s death.
Romero Flores entered a not guilty plea at arraignment and was remanded without bail, meaning he will remain in custody as the case moves forward through the Nassau County court system. The two-month gap between the March 19 crash and the May 29 arrest is not unusual in fatal crash investigations; Nassau County police and prosecutors typically take time to ensure the evidentiary record is solid before filing felony charges, particularly in cases where the initial circumstances may require medical examiner confirmation of cause and manner of death.
Broader Impact
In New York State, a manslaughter conviction in a vehicular context — particularly one grounded in reckless driving — can result in a sentence of up to 15 years in prison, with the defendant also subject to license revocation and civil liability. The filing of four separate charges against Romero Flores, including both manslaughter and criminally negligent homicide, suggests Nassau County prosecutors are building a layered case designed to withstand legal challenges at multiple levels. Drivers on Long Island roads should be aware that fatal crashes resulting from reckless or negligent driving are treated with the full weight of felony prosecution under New York law — even when an arrest comes weeks or months after the incident itself.
