HUDSON COUNTY, NJ — Detective Joseph Seals was one of the most respected officers in the Jersey City Police Department. He was a father, a husband and a lifesaver. But only hours after his death at the hands of armed assailants in a Jersey City standoff, a wave of unscrupulous scamsters are already trying to profit off his good name, authorities say.

On Tuesday, Seals was among four victims killed by a pair of heavily armed shooters in Jersey City. Three civilians also lost their lives in the violence: Leah Mindel Ferencz, 32, Moshe Hersh Deutsch, 24, and Douglas "Miguel" Rodriguez, 49. Police fatally shot the two suspects, David Anderson, 47, and Francine Graham, 50.

Carpenito and Attorney General Gurbir Grewal urged people to be vigilant about possible scams and to report them to authorities. Earlier in the day, the Union City Police Department also warned the public that several fake fundraising campaigns have been set up in Seals' name online.

"Please do not donate to any GoFundMe or other online memorial for Det. Seals until these sites can be vetted or until they are set up by appropriate parties (family, fraternal organizations, etc.) and proper notifications have been made," Union City police stated.

"Please advise family, friends and others also not to patronize these likely illegitimate pages," police added.
