Authorities: Kosher store shooters planned attack for months

NEWARK, N.J. — The two people who fatally shot a police officer then killed three people at a kosher grocery in Jersey City planned an assault for some time and were equipped to cause greater destruction, authorities said Monday.

State and federal law enforcement officials revealed details about the months leading up to the shootings by David Anderson and Francine Graham, a couple who expressed hatred of Jews and law enforcement in notes left at the grocery shooting scene and in online posts.

“This was a senseless and cowardly act,” U.S. Attorney Craig Carpenito said.

Anderson, 47, and Graham, 50, shot and killed Jersey City Detective Joseph Seals in a chance meeting in a cemetery Dec. 10, then drove to the market and killed Mindel Ferencz, 31, who owned the store with her husband; Moshe Deutsch, 24, a rabbinical student from Brooklyn who was shopping there; and store employee Douglas Miguel Rodriguez.

Rodriguez held the back door open for a wounded customer to escape before he was shot, authorities said Monday.

Five weapons and hundreds of rounds of ammunition were found in the store afterward. Investigators also found a bomb in the couple's van that could have sprayed shrapnel fragments “five football fields long,” Gregory Ehrie, special agent in charge of the FBI in Newark, said. The van also contained materials that could have made a second bomb, he said.

It's not known for certain what prompted the confrontation between Seals and the shooters. Officials speculated that Seals, a 13-year veteran who was meeting someone about returning a car that had been impounded, may have stopped the U-Haul van Anderson and Graham were driving because it fit the description of a vehicle connected to the slaying of a livery car driver in Bayonne a few days earlier.

In doing so, Seals may have thrown off their plans and prevented more bloodshed, Carpenito said, but he did not provide more detail.

Anderson and Graham bludgeoned and then shot the livery driver Michael Rumberger, 34, officials said, though it wasn't clear if he had been targeted. The pair also had done online research on a Jewish center in nearby Bayonne in the days before the attack in Jersey City, Carpenito said.

Barricaded in the kosher store, Anderson and Graham were killed after a lengthy gun battle with the police that sent the sound of gunfire booming for hours through the neighborhood in New Jersey's second-largest city, across the street from a school.

A gun recovered at the kosher grocery that was used by Anderson and Graham to kill Rumberger also was used to shoot out the windows of a car driven by a Hasidic man on a highway near Jersey City, the investigation revealed. That man was not injured.

That shooting wasn't reported until investigators began probing the market shootings.

“Up until the attack, there wasn't anything that would have put either of them on anybody's radar,” Ehrie said.

But surveillance video showed Anderson and Graham had driven past the market in their rented U-Haul van twice in the week leading up to the shootings, Carpenito said.

At the scene, a note found on Anderson contained a reference to a 1990s documentary, “The FBI's War on Black America,” which explored the FBI's targeting of individuals involved in the civil rights movement in the 1960s, Carpenito said. He added that a time-stamp written on the note corresponded to a segment in the documentary where an interviewee advocates killing “fascist pig cops.”

Investigators found among Anderson’s social media posts a reference to Jews as “impostors who inhabited synagogues of Satan."

Anderson received about $560 per month as a military veteran and may have sold property and a van to make money, officials said, but investigators have found no evidence he received outside assistance to purchase weapons or bomb-making materials.
