UPDATED, 12:30 p.m., May 18: Isaac Rosenberg, a Brooklyn real estate investor and developer and a member of Williamsburg’s Satmar Hasidic community, died Tuesday morning after drowning off the coast of North Miami Beach, Fla.

Rosenberg and three other men were swimming in an unguarded area of the beach when they were caught by a current and swept into the Atlantic Ocean, according to local ABC News reports and Orthodox Jewish community outlet VIN News.

While two of the men, identified as Aron Wurzberger and Yitzchok Englander, escaped the current and are in stable condition, Rosenberg and another companion, Chaim Parnes, had to be rescued and were rushed to a local hospital, where they were pronounced dead.

Rosenberg, believed to have been in his 60s, was active in the Brooklyn real estate market alongside his brother, Abraham. He also went by the name “Isack.”

Among Rosenberg’s real estate assets is a massive property on Kent Avenue, along the Williamsburg waterfront, that Ziel Feldman’s HFZ Capital Group and former Vornado Realty Trust CEO Michael Fascitelli were reportedly eying for north of $250 million.
