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.
The Victims
| Name | Age | From | Who They Were |
|---|---|---|---|
| Emilia Rennhack | 30 | Deer Park | Off-duty NYPD officer |
| Jian Chai Chen | 37 | Bayside, Queens | Co-owner of Hawaii Nail & Spa |
| Yan Xu | 41 | Flushing, Queens | Salon employee |
| Mei Zi Zhang | 50 | Flushing, Queens | Salon employee |
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.
The Legal Path to Trial
| Date | Event |
|---|---|
| June 28, 2024 | Crash at Hawaii Nail & Spa — 4 killed, 9 injured |
| June 28, 2024 | Schwally arrested, charged with DWI |
| August 2024 | Upgraded charges: second-degree murder (depraved indifference) |
| November 2025 | Schwally rejects plea deal — 22 years to life for guilty plea to second-degree murder |
| May 2026 | Schwally rejects second plea deal |
| May 11, 2026 | Murder trial begins in Riverhead before Supreme Court Justice Timothy P. Mazzei |
| May 26, 2026 | Schwally suffers heart attack — trial continues without him |
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.
