The FBI was at the Goshen office of Grafton Thomas’ attorney Friday to seize materials that Michael Sussman collected from a home where the Monsey stabbing suspect lived.

The FBI issued a subpoena to seize material Sussman says he took out of the Wurtsboro cabin of Thomas’ mother, where Thomas lived for several years before moving out in 2018.

But Sussman says he has a responsibility to his client to chronicle all the evidence before he hands it over to federal authorities.

To date, Sussman says his forensic team hasn't found anything suggesting Thomas is anti-Semitic in the items taken from the Wurtsboro home, which include books, journals, a cellphone and a computer.

"We found one swastika in the material, and that was surrounded by writing that said to the effect, ‘How did a symbol of prosperity become corrupted into a symbol of destruction?’" says Sussman.

Sussman says he's filing an appeal with a federal judge that would allow him to finish chronicling the evidence before it can be inspected.

Sussman says he visited Thomas in jail just moments before federal agents arrived at his law office. He says Thomas has deteriorated since earlier the week and is now "entirely confused and relatively incoherent."
