May 26, 2026. The murder trial of Steven Schwally — the Dix Hills man accused of driving drunk at 78 mph into a Deer Park nail salon in June 2024, killing four people and injuring nine — took a dramatic turn today when Schwally’s attorney announced that the 66-year-old defendant suffered a heart attack. The presiding judge ruled the trial will continue without him.


The Crash — June 28, 2024

On the afternoon of Friday, June 28, 2024, Steven Schwally, then 64, drove his SUV into Hawaii Nail & Spa on Grand Boulevard in Deer Park at approximately 78 miles per hour.

The vehicle plowed through the front of the salon where customers and employees were inside. Four people were killed. Nine were injured.

Emilia Rennhack was an off-duty NYPD officer — a young woman getting her nails done on her day off. Her death drew national attention and outrage.


What Prosecutors Say Happened

According to the Suffolk County District Attorney’s Office, Schwally’s actions in the hours before the crash paint a picture of deliberate, sustained impairment:

  • Schwally had been living in motels for more than a year, including the Commack Motor Inn on the day of the crash
  • He purchased liquor earlier that day
  • He drove for hours while intoxicated before the crash
  • His SUV was traveling at 78 mph at the moment of impact — on a commercial boulevard with a 30-40 mph speed limit
  • When hospital staff treated him after the crash, he told them he had injured himself in a fall — not that he had crashed into a building
  • He also told hospital staff he had not been drinking — but a responding officer testified that Schwally’s eyes were bloodshot and glassy, his speech was slurred, and his breath “reeked of liquor”
  • Schwally had a prior DWI conviction from 2014

The Defense

Defense attorney Christopher Cassar has argued that Schwally had a leg disability that prevented him from moving his foot off the gas pedal — suggesting the crash was caused by a physical incapacity, not willful intoxication.

Why Second-Degree Murder, Not Just DWI?

In New York, DWI-related deaths can be charged as murder when the defendant’s conduct demonstrates “depraved indifference to human life” (Penal Law §125.25(2)). Prosecutors must show that the defendant was aware that their conduct created a grave risk of death and consciously disregarded that risk.

The factors that elevate this from vehicular manslaughter to murder:

  • Prior DWI conviction — Schwally knew the dangers of drunk driving from personal experience
  • 78 mph in a commercial zone — speed alone demonstrates extreme recklessness
  • Hours of impaired driving before the crash — this wasn’t a momentary lapse
  • Lying to hospital staff about drinking — consciousness of guilt

If convicted of second-degree murder, Schwally faces 25 years to life in prison — for each count. With four victims, sentences could potentially run consecutively.


Today’s Development: Heart Attack Mid-Trial

News12 Long Island reported today that Schwally’s defense attorney informed the court that the 66-year-old defendant suffered a heart attack.

The presiding judge ruled that the trial will resume without Schwally present — a legally permissible but unusual step. Under New York law, a defendant’s right to be present at trial can be forfeited if the defendant’s absence is voluntary or caused by the defendant’s own conduct, or if the trial’s continuation is necessary to prevent prejudice to the prosecution or injustice to the victims.

The families of four dead victims have waited nearly two years for this trial. The court is not going to let it stop now.


The Bigger Picture: DWI Killings on Long Island

The Deer Park nail salon crash is the deadliest DWI incident on Long Island in recent memory. It exposed several systemic failures:

  • Schwally had a prior 2014 DWI conviction — he was still driving. New York’s license revocation and interlock device requirements failed to keep a repeat offender off the road.
  • 78 mph on Grand Boulevard — a road with no physical barriers between vehicle traffic and storefront pedestrians. The crash reignited calls for bollard installation in front of commercial storefronts.
  • The “100 Deadliest Days” — the crash occurred during the Memorial Day-to-Labor Day window when DWI fatalities spike. We are currently in that same window right now.

This case became a catalyst for Suffolk County’s expanded DWI enforcement — including the SoToxa saliva testing kits we reported on this week, which are being deployed specifically to catch impaired drivers before they kill.


The trial is expected to continue in Riverhead. We will update this article as proceedings develop.

Frequently Asked Questions

What should I do if I'm in a car accident on Long Island?

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.
