RIVERHEAD – The estate of a New York City police sergeant, whose neighbor and fellow officer is accused of shooting her to death in front of her 8-year-old daughter, has permission to file a notice of claim against Suffolk County, its police department and the brother of her accused killer.

Johnnie L. Cochran Jr., representing the slain woman’s estate and her daughter, sought to serve the county with a notice of claim seeking $100 million in damages for wrongful death and civil rights violations. The county previously rejected it as untimely. But on June 18, Justice Harry E. Seidell ordered Suffolk to accept service after finding it had sufficient notice of the underlying criminal case.
