Leah Minda Ferencz co-owned the Kosher grocery store in Jersey City targeted by two gunman.

Miguel Douglas was a store employee, married with an 11-year-old daughter, who had immigrated to the U.S. from Ecuador.

Moshe Deutsch was inside the store getting a sandwich when the shooting erupted.

All three who were killed inside the store — along with Jersey City Police Detective Joseph Seals, fatally shot about a mile away — were remembered Wednesday as selfless friends and colleagues who all found ways to make a difference in their communities.

Ferencz, 33, owned JC Kosher Supermarket with her husband, who was not inside when the shooting began.

The mother of 3 was described as a “pioneer” by the United Jewish Organizations (UJO) of Williamsburg and North Brooklyn.

“She and her husband were of the very first to relocate from Williamsburg, due to the sky-rocketing prices of housing, to settle in Jersey City,” read the statement from UJO.

“They did not do it for themselves, but to pave the way for a new community that lives harmoniously with their neighbors. She was a caring and nurturing mother for her three children, and at the same time helped her husband who ran the first kosher grocery in the area,” continued the statement.

“A life of selflessness, and dedication to others, full of love, was cut short by vicious hate-filled murders,” it concluded.

Her husband, Moishe Ferencz, had left the store shortly before the attack for an afternoon service at a nearby synagogue, according to Rabbi Moshe Schapiro, co-director of the Chabad of Hoboken and Jersey City synagogue and acting as an informal spokesman for the local Hasidic community.

His mother, Victoria Ferencz, told the New York Times that shots were heard within minutes and the synagogue was placed on lockdown.

“I called my son, he says, ‘I’m locked here, I have no idea where she is,’” said Victoria Ferencz.

Rabbi David Niederman, the UJO’s executive director, said he did not know Douglas, 49, but offered a tribute when speaking in New York City on Wednesday with Mayor Bill de Blasion.

“May he rest in peace,” Niederman said.

“He served everyone who came into that place fairly, and Our heart goes out. He’s also part of what we now call a list of dead people because of horrific, criminal activity," Niederman said.

Williams Machazek, pastor of Iglesia Nueva Vida, told NorthJersey.com Douglas was married with an 11-year-old daughter and had moved to the U.S. from Ecuador and was working at the market to support his family.

Douglas appeared to also go by the name of Douglas Rodriguez. A woman who said she was the man’s niece wrote online that he came to America for a better life with his wife and daughter.

“He was a devoted husband, friend, and father. He was a God-loving, honest and hard-working person was who always available to help others. He had been working at the store for about a year before this is devastating and unexpected loss,” she wrote.

Deutsch, 24, lived in Brooklyn.

His father, Abe Deutsch, is a board member at the Williamsburg/North Brooklyn UJO.

The organization said that he “followed in his father’s footsteps and devoted his spare time and energy to help organize the UJO Passover food distribution and many other acts of kindness.”

“The community lost a promising-upcoming charitable person who was spreading love and kindness,” UJO said in its statement.

Deutsch also was a volunteer at New York City-based Chai Lifeline, which offers support for seriously ill children and their families, and served as a volunteer in their annual cycling event

“Moshe embodied the very best of Chai Lifeline, said Rabbi Simcha Scholar, CEO of Chai Lifeline.

“He was a dedicated volunteer who always looked for opportunities to help others. This is a devastating loss for our entire community and our thoughts are with all those impacted by this senseless act of violence,” Scholar said.
