Josef Neumann, a victim in the Monsey stabbing attack last Chanukah has died.

“We are sad to inform you that Yosef Neumann, who was stabbed during the Chanukah attack in Monsey late Dec. 2019, passed away this evening,” the Orthodox Jewish Public Affairs Council tweeted on Sunday.

During the attack, Neumann sustained serious injuries to his brain, neck, and right arm.

In February, doctors were optimistic Neumann would recover after he opened his eyes and began breathing on his own.

“We were hoping when he started to open his eyes,” Rabbi Yisroel Kahan, the community liaison for the Ramapo Police Department, told The Journal News on Sunday.

“We were hoping and praying he would then pull through. This is so very sad he was killed celebrating Chanukah with friends just because he was a Jew,” he added.

Neumann was a father of seven children, a grandfather, and a great-grandfather.

On Dec. 28, 2019, Grafton Thomas stormed into the home of Rabbi Chaim Rottenberg in Monsey, NY and hacked the 72-year-old and four other Orthodox Jews with a machete during a Chanukah party.

In January, Thomas pleaded not guilty on six counts of attempted murder and 10 federal hate crimes charges. Because Neumann died, it is expected prosecutors will seek the death penalty.
