The East Village gas explosion tore through 121 Second Avenue in Manhattan on March 26, 2015, killing two men, injuring more than 20 others, and leveling three buildings. Investigators traced the blast to an illegally rigged gas line in the basement. In November 2019, building owner Maria Hrynenko, contractor Dilber Kukic, and unlicensed plumber Athanasios “Jerry” Ioannidis were convicted of manslaughter and related charges, and two months later each was sentenced to four to twelve years in state prison.1New York Times.

What Caused the Explosion
The seven-alarm fire erupted near the corner of Second Avenue and East 7th Street on a Thursday afternoon. Two men died: Nicholas Figueroa, 23, who was on a date at the ground-floor Sushi Park restaurant, and Moises Ismael Locon Yac, 27, a busboy at the same restaurant.2CBS News. East Village Explosion Sentencing
Investigators found that someone had rigged a system of pipes, valves, and a rubber hose in the basement to bypass the Con Edison gas meter. The setup routed gas to newly renovated upstairs apartments without going through the utility’s metering, siphoning gas to units that had not been cleared for occupancy.3NBC New York. East Village Explosion Investigation Prosecutors later called the disaster “foreseeable, preventable, and completely avoidable.”4ABC News.

The warnings had been there. In August 2014, inspectors found the rubber hose bypassing the meter and ordered an immediate shutdown until the violations were corrected. No criminal charges were brought at that point.5NBC New York.

Who Was Charged
Nearly a year after the blast, on February 11, 2016, the Manhattan District Attorney’s office announced charges against five people: building owner Maria Hrynenko; her son Michael Hrynenko, who managed the property; general contractor Dilber Kukic; unlicensed plumber Athanasios “Jerry” Ioannidis; and Andrew Trombettas, a licensed plumber accused of lending his credentials to the job.6New York Times. 5 Arrested in Connection With East Village Gas Explosion
The charges against Maria Hrynenko included two counts of second-degree manslaughter, nine counts of second-degree assault, two counts of criminally negligent homicide, four counts of third-degree assault, and one count of second-degree reckless endangerment. Michael Hrynenko faced the same charges.7NYC Department of Investigation.

Convictions and Sentences
The trial began in September 2019 in New York State Supreme Court, New York County, before Justice Michael J. Obus. After two days of deliberation, the jury returned guilty verdicts against all three defendants on November 15, 2019.10Fox 5 New York.

The Appeal
Hrynenko and Kukic appealed, arguing that the evidence was legally insufficient, that the verdicts were against the weight of the evidence, and that the trial court had improperly replaced a sworn juror with an alternate. On June 22, 2021, the Appellate Division, First Department, rejected each argument and affirmed the convictions. The court found the proof was “legally sufficient to prove that defendants recklessly caused the victims’ deaths” by circumventing safety regulations and operating an unauthorized gas-delivery system, and it held that the trial judge had properly exercised discretion in substituting a juror who faced a compelling personal hardship.9FindLaw. People v Kukic, Appeal No. 13870-71
Federal habeas corpus proceedings filed by the defendants were still pending in the U.S. District Court for the Southern District of New York as of 2023.12Justia. Matter of 121 Second Ave. Gas Explosion Litigation
Where the Defendants Are Now
None of the three served the full minimum sentence. Maria Hrynenko was released in October 2023 after roughly 20 months in custody; the reason for her early release has not been publicly explained. She remains under post-release supervision through April 2026. Kukic served time at Wallkill Correctional Facility and was paroled in February 2025. Ioannidis was still incarcerated at the Adirondack Correctional Facility in Essex County, New York, as of March 2025, with parole eligibility beginning in September 2025.13EV Grieve.

The Civil Cases
The blast triggered a wave of civil suits. In 2016, the estate of Nicholas Figueroa, administered by his mother Ana Lanza, filed a wrongful death case in New York State Supreme Court naming the Hrynenkos, Sushi Park, the City of New York, Con Edison, and several contractors.14The Real Deal.

Matter of 121 Second Ave. Gas Explosion Litigation
Con Edison and the City of New York reached a private agreement through court-ordered mediation to allocate liability between themselves. Plaintiffs tried to compel disclosure of the terms, but a court ruled in 2022 that the agreement was not collusive and its contents were not subject to disclosure. The Appellate Division affirmed that ruling in 2023.16FindLaw. In Re Gas Explosion Litigation 1644
In 2017, Maria Hrynenko sold 119 and 121 Second Avenue for $9.15 million to Avenue Second Owner LLC, an entity controlled by developer Yaniv Cohen’s Nexus Building Development Group. Victims filed a motion asking a judge to freeze the sale proceeds so she could not dispose of them before civil claims were resolved.17The Real Deal.

The Site and the Law That Followed
Nexus redeveloped the lots into a seven-story, 21-unit condominium building designed by Morris Adjmi Architects, with ground-floor retail. Some neighborhood residents had pushed for affordable housing on the site for those displaced by the explosion rather than luxury condos.18CooperatorNews.

The disaster, together with a 2014 gas explosion in East Harlem, pushed the New York City Council to pass a package of ten gas-safety bills. The Council approved the legislation 50 to 0 on November 16, 2016, and Mayor Bill de Blasio signed it into law on December 6, 2016. The changes ended the Department of Buildings’ self-certification program for gas systems, required DOB inspections of all gas piping, mandated periodic inspections by licensed master plumbers, and classified operating a gas system without a permit as an immediately hazardous violation. The laws also required building owners to give tenants gas-leak safety instructions and led to natural gas detector standards under Local Law 157, with a compliance deadline of May 1, 2025.20CityLand.
