A review of security footage from the store during the Tuesday-afternoon shooting that left five people dead, including the two suspects, made it “clear” that the gunmen chose the Jewish establishment, Jersey City Mayor Steven Fulop (D) said on Twitter.

“I’m Jewish and proud to live in a community like Jersey City that has always welcomed everyone,” Fulop wrote on Twitter. “It is the home of Ellis Island and has always been the golden door to America. Hate and anti-semitism have never had a place here in JC and will never have a place in our city.”

Authorities have not revealed the identities of the attackers, nor of the victims, though Matzav.com yesterday first reported that the attack claimed the lives of 33-year-old Mrs. Leah Mindel Ferentz z”l of Jersey City (pictured), wife of Reb Moshe Dovid Ferentz, the owner of the JC supermarket, and a daughter of Reb Binyomin Hersh Greenfeld, and habochur Moshe Hersh Deutch z”l , 24, of Williamsburg, son of Reb Shalom Deutch and a cousin of Mrs. Ferenz.

But the attack remains shrouded in mystery.

Authorities are still investigating and have not indicated a motive for the attack. Before the mayor’s tweets today, investigators had said the store was chosen at random and was not indicative of a hate crime.

“Why did they say that when it is clearly untrue?” a community activity asked, speaking on condition of anonymity. “And why were there rumors of a drug bust gone bad and a homicide investigation when that was clearly not the case?”

The activist said that it is understandable that sometimes details must be withheld as an investigation is conducted, but “certain basic details should be revealed, and in this case, there’s been zero information available to a community that is on edge.”

The sixth victim, Jersey City Police Detective Joseph Seals, was shot by the suspects as he approached them at Bayview Cemetery in the city’s Greenville neighborhood, Jersey City Police Chief Michael Kelly said. According to reporting from the New York Times, the suspects were inside a U-Haul vehicle that had been linked to a homicide over the weekend.

The attackers then fled to the kosher market, where they exchanged more fire with authorities and were killed. Three other people, believed to be bystanders, were also among the dead in the store, Kelly said.

“Our officers were under fire for hours,” the chief said.

Seals, a 15-year veteran of the Jersey City force, was a father of five, authorities said. In recent years, Seals led the police department in the number of illegal guns removed from the city’s streets, reported the Associated Press.

“He was a good cop,” Kelly said.

Two other officers were also shot, Kelly said. They were treated and released from the hospital.

“It’s a really tough day for the city of Jersey City,” Fulop, the mayor, said at a news conference Tuesday evening.

The store owner, Reb Moshe Ferencz, spoke with Chabad Rabbi Moshe Schapiro about the attack, who then shared the description with the Associated Press.

“He told me he had just walked out of the store into the synagogue not five feet away just before this happened, and then he couldn’t get back for hours,” Rabbi Schapiro told the AP. “His wife was inside the store. He said, ‘I hope my wife is safe.’”

Officials have not disclosed the identities of the suspects or of the others killed at the store. But they described a difficult and dangerous episode that began shortly after noon in a residential community, near schools and stores, further complicated by the two suspects’ near-constant movement.

“Their movement was rapid and continuous for four hours within that area,” Kelly said.

Police also recovered the stolen U-Haul vehicle that Kelly said “may contain an incendiary device” and that bomb squads were investigating.

Video and photographs from the scene showed throngs of heavily armed officers from a patchwork of agencies converging on the northeastern New Jersey city, which sits between Newark and the southern tip of Manhattan. The Bureau of Alcohol, Tobacco, Firearms and Explosives in Newark said its agents were responded, along with other New Jersey authorities and special operations officers from the New York Police Department.

The violence prompted the lockdown of the Satmar cheder located next to the store, as well as lockdowns of all 43 of the city’s public schools, Jersey City Board of Education President Sudhan Thomas told local media.

“All students and staff are safe,” the School District of Jersey City said in a statement.

New Jersey Gov. Phil Murphy said in a statement that his thoughts and prayers are with officers shot.

“Today reminds us of their bravery and the sacrifices they, and their families, make for our communities,” Murphy said.

The state’s police officer union said that its “officers have come under attack and we have several wounded.”

“Today is a horrific day,” the New Jersey State Policemen’s Benevolent Association said in a tweet. In another, the union added: “We need a lot of prayers right now for Jersey City officers.”
