A Brooklyn-based Orthodox Jewish group donated $47,000 to the family of a Jersey City police detective killed in the line of duty.

The Flatbush Jewish Community Coalition donated the money to Detective Joseph Seals’ family on Tuesday. Seals died in a shootout with two gunmen in a Jersey City cemetery on Dec. 10. Those gunmen went on to kill three people inside of the JC Kosher Supermarket.

Authorities say that the pair targeted members of the Jewish and law enforcement communities.

“Simply expressing outrages and sadness, at least to us, wasn’t enough,” says Chaskel Bennett. “We felt like we needed to transform that anger, that dismay, that sadness, into tangible action.”

The Jersey City Police Officers Benevolent Association accepted the donation on the Seals family’s behalf.
