Today marks one year since the deadly Hanukkah attack in Monsey.

On Dec. 28, 2019, police say Grafton Thomas stabbed five people at a rabbi's home.

One of those victims died in March. "Violence of any kind is not to be tolerated.  It was a horrific situation. It’s frustrating when you see somebody come from outside our wonderful county to commit a crime such as this.  We must remember that there's much more that joins us, than separates us," says Rockland County Executive Ed Day.

Earlier this month a government forensic psychologist found Thomas is unfit to stand trial. The doctor diagnosed him as a schizophrenic, with severe symptoms.

The U.S. Attorney's office would still like a hearing held to determine whether further treatment will improve his condition. But his lawyers say he should be sent to a psychiatric facility.
