News 12 is continuing to follow the tragic case of a former federal prosecutor and family court activist from Westchester who died during a court battle for her kids and a terminal cancer diagnosis.

Catherine Kassenoff emailed supporters last Saturday saying that she chose assisted suicide in Switzerland rather than living with the “unbearable pain” of being unable to see her children during her divorce while terminally ill

Kassenoff blamed her estranged husband Allan Kassenoff and the Westchester County court system for contributing to her decision, citing alleged unfair rulings, favoritism and forensic evaluations by officers of the court with conflicts of interests.

The law firm where Allan Kasanoff works, Greenberg Traurig, issued a statement online saying they’re conducting an internal investigation and that Kassenoff is taking a voluntary leave of absence to focus on his family.

News 12 reached out to Kassenoff but he declined to comment.

The Westchester District Attorney’s Office says they investigated Catherine’s concerns about her case in 2021 but found nothing criminal.

A celebration of Catherine Kassenoff’s life and vigil will be held Monday night at the Stanz Café in Larchmont beginning at 5:30 p.m.
