A Manhattan jury Friday convicted all three defendants in the deadly 2015 gas explosion that killed two people and leveled three East Village buildings.

After two days of deliberations, the jury convicted landlord Maria Hrynenko, contractor Dilber Kukic and unlicensed plumber Athanasios “Jerry” Ioannidis of manslaughter, assault, reckless endangerment and other charges.

Relatives of the defendants and of the two victims were in the audience at Manhattan Supreme Court, and many broke into tears at the verdict.

The forewoman trembled and dabbed her eyes with a tissue as she announced “guilty” on each count.

Ana Lanza, the mother of 23-year-old Nicholas Figueroa, who perished in the blaze, said the jurors made the right decision.

“I don’t want to put anyone in jail but because they did something wrong and lives were lost, they have to pay,” she said. “They can’t get away with it.”

The three defendants illegally diverted gas from 119 Second Ave. to 121 Second Ave., between East Seventh Street and St. Marks Place — both buildings owned by Hrynenko, Manhattan prosecutors Randolph Clarke Jr. and Rachana Pathak argued.

Hrynenko wanted to rent out four newly renovated apartments before Con Ed signed off on the new meters, the prosecutors said.

The defendants used a series of pipes and valves hidden behind a locked door to supply the gas to 121 Second Ave., which housed the ground floor restaurant Sushi Park.

The explosion happened March 26, 2015, after Kukic shut off the gas before a scheduled Con Ed inspection related to the new meters.

Once Con Ed left, Kukic and Hrynenko’s now-deceased son Michael Hrynenko Jr. turned the illegal gas hook-up back on, allowing gas to stream into the basement for 23 minutes until it ignited into a fireball.

The inferno reduced the buildings to rubble, killing Figueroa, who was on a lunch date at the restaurant, and 26-year-old Moises Locon, a busboy.

More than 14 were injured, among them several firefighters.

Defense lawyers argued that the cause of the explosion was unclear and that the defendants didn’t believe that the rigged gas system was dangerous.

Justice Michael Obus allowed the defendants to remain free on bail until they’re sentenced Jan. 10.

Each defendant faces a minimum of probation and as much as 15 years on the top count of second-degree manslaughter.

Lanza said as she left the courthouse, “No matter how much time they get it’s never going to bring my son back.
