What Happened

Steven Schwally of Dix Hills appeared in court Monday for opening statements in his trial for the horrific crash that killed four people at Hawaii Nail and Spa in Deer Park on June 28, 2024, according to CBS New York. The 64-year-old defendant does not deny causing the devastating crash nearly two years ago but maintains he was not intoxicated at the time, despite facing more than a dozen charges including depraved indifference murder.

Prosecutors told jurors that Schwally made his nearly daily stop at a liquor store on the day of the crash to purchase two bottles of Long Island iced tea before the incident occurred. Surveillance video captured Schwally’s vehicle barreling through the parking lot at 78 miles per hour before ramming into the business on Grand Avenue “like a missile, with such velocity, obliterating everything in its way,” prosecutors said during opening statements.

The crash killed four people: salon owner Jiancai Chen, 37; employees Meizi Zhang, 50, and Yan Xu, 41; and off-duty NYPD officer Emilia Rennhack, 30, who was a newlywed to a detective. Nine additional people were hospitalized, including a 12-year-old girl, and Schwally himself was also injured in the crash, according to prosecutors.

Blood alcohol testing revealed Schwally’s level was .17, more than twice the legal limit of .08, prosecutors stated in court. However, defense attorney Christopher Cassar disputed the intoxication claims, arguing his client was a handicapped driver whose right leg locked up on the gas pedal during the incident. “He was not intoxicated, and from Day 1 we said he had a problem with his leg and he could not remove his leg from the gas pedal,” Cassar told the court.

The defense team also challenged the blood alcohol test results, with Cassar claiming the evidence was “contaminated” and therefore inaccurate. Additionally, Schwally’s attorney argued that video footage of the crash shows his client attempted to avoid the collision, contradicting the prosecution’s narrative of reckless driving.

Schwally entered the courtroom sporting a new haircut and using a walker, reportedly staring straight ahead and avoiding eye contact with prosecutors and jury members. His defense attorney apologized for his client’s role in causing the crash while maintaining the defendant’s innocence regarding intoxication charges.

Location & Road Context

The tragic incident occurred at Hawaii Nail and Spa on Grand Avenue in Deer Park, a busy commercial corridor in Suffolk County. Grand Avenue serves as a major thoroughfare through the community, lined with various businesses and shopping centers that draw heavy pedestrian and vehicle traffic throughout the day. The location’s proximity to residential areas and commercial establishments makes it a frequently traveled route for local residents and visitors.

Schwally faces up to 27 years to life in prison if convicted on all charges, including the most serious charge of depraved indifference murder. The defendant rejected a plea deal that would have resulted in 22 years to life in prison, choosing instead to proceed to trial. The prosecution’s case relies heavily on surveillance footage showing the high-speed impact and blood alcohol evidence, while the defense strategy centers on challenging the intoxication findings and presenting a medical defense related to Schwally’s claimed leg disability.

The trial represents nearly two years of legal proceedings following the June 2024 crash, with both prosecution and defense teams preparing extensive evidence and witness testimony. The depraved indifference murder charge indicates prosecutors believe Schwally’s actions demonstrated a reckless disregard for human life, beyond typical vehicular manslaughter charges.

Broader Impact

This case highlights the severe legal consequences facing drivers in New York who cause fatal crashes while allegedly intoxicated, with depraved indifference murder charges carrying potential life sentences significantly longer than standard DWI-related vehicular manslaughter convictions. The prosecution’s decision to pursue the most serious charges available reflects the devastating scope of the incident, which claimed four lives and injured nine others, including a child, in a single catastrophic event.

Frequently Asked Questions

What should I do if I'm in a car accident in Deer Park?

Call 911 immediately if anyone is injured or if the vehicles can't be moved safely off the roadway. Stay at the scene — leaving the scene of an accident with injuries is a crime under New York Vehicle and Traffic Law §600. Exchange license, registration, and insurance information with every other driver involved. Take photographs of every vehicle, the position of the vehicles before they're moved, all license plates, the road surface, traffic signs, and any visible injuries. Get the names and phone numbers of every witness — police often won't capture bystander witnesses on their own. Seek medical attention within 24 hours even if you feel fine; soft-tissue injuries and concussions can take a day or two to present, and a delayed medical visit weakens an injury claim. In Nassau County, NCPD responds outside of incorporated villages. In Suffolk County, SCPD covers the five western towns; East End towns have their own forces. New York State Police Troop L responds to accidents on state highways across both counties.

How long do I have to file a no-fault claim in New York?

Thirty days. New York Insurance Law §5102 requires you to file a Personal Injury Protection (PIP/no-fault) application with the insurer of the vehicle you were in (or, if you were a pedestrian or cyclist, with the insurer of the striking vehicle) within 30 days of the accident. Missing the 30-day deadline can void your no-fault benefits — that's up to $50,000 in medical bills and 80% of lost wages (capped at $2,000/month) per injured person. The form is the NF-2 application; your insurance carrier provides it on request. New York no-fault is a true PIP system: it pays regardless of who caused the crash.

What counts as a "serious injury" under New York law?

Under Insurance Law §5102(d), a "serious injury" is one that meets at least one of these categories: (1) death; (2) dismemberment; (3) significant disfigurement; (4) a fracture; (5) loss of a fetus; (6) permanent loss of use of a body organ, member, function, or system; (7) permanent consequential limitation of use of a body organ or member; (8) significant limitation of use of a body function or system; or (9) a medically determined injury that prevents the injured person from performing substantially all daily activities for at least 90 of the first 180 days following the accident. Only injuries that meet one of these nine categories create the right to sue the at-fault driver for pain and suffering damages — short of that threshold, recovery is limited to no-fault PIP benefits. Disputes over whether an injury meets the threshold are the single most-litigated issue in NY motor-vehicle cases.

How long do I have to sue after a Long Island car accident?

Three years from the date of the accident for personal injury claims under CPLR §214(5). Wrongful death claims have a two-year deadline under EPTL §5-4.1. If a government entity is involved (a county vehicle, a road defect on a state highway, a defective traffic signal, a county bus), you must file a Notice of Claim within 90 days under General Municipal Law §50-e — that's a non-negotiable jurisdictional deadline, and missing it usually bars the claim entirely. Property-damage-only claims have the same three-year clock. The clock starts on the day of the accident, not the day you discover the full extent of an injury.

Can I still recover compensation if I was partly at fault?

Yes. New York is a pure comparative negligence state under CPLR §1411. Even if you were 90% at fault, you can still recover 10% of your damages. (A pending 2026 budget proposal would change this to a 51% bar — meaning a plaintiff who is more than 50% at fault would recover nothing — but that hasn't passed.) Insurance carriers routinely try to inflate the injured driver's percentage of fault to reduce payouts. The percentage assignment is decided by the jury at trial (or negotiated during settlement); it isn't fixed by the police accident report and isn't binding even when the report assigns fault. Reporting practice and the actual legal apportionment are separate questions.

Who can file a wrongful death claim in New York?

Under EPTL §5-4.1, only the personal representative (executor or administrator) of the deceased's estate can bring a wrongful death action — not the deceased's family directly. The estate is opened in Surrogate's Court of the county where the deceased lived. Damages flow to the spouse, children, parents, and other distributees defined under EPTL §4-1.1. Recoverable damages include loss of financial support, loss of parental guidance for surviving children, and conscious pre-death pain and suffering (recovered through a separate "survival action" under EPTL §11-3.2). New York is unusual in NOT allowing surviving family members to recover for their own emotional grief — only economic losses to the estate. The wrongful-death two-year statute of limitations is shorter than the three-year personal-injury statute, so the deadline is critical.

How do I get a copy of the police accident report?

If local police responded to the scene, the report is filed under an MV-104A form. In New York State, you can request a copy through the DMV at https://dmv.ny.gov/vehicle-safety/get-copy-accident-report (roughly $7 online, $10 by mail) once the responding agency has uploaded it to the state system, which usually takes 5-10 business days. NCPD and SCPD also have their own direct-request processes through the precinct that responded. If you weren't injured but the property damage exceeded $1,000, New York VTL §605 requires you (the driver) to file your own MV-104 report with the DMV within 10 days regardless of whether police responded.
