Kathleen Denise Castor was 27 when she and her 63-year-old mother, Wanda Castor, were found shot to death in their Lake Road home in Valley Cottage, New York, on May 26, 2020. Kathleen had been a new mother; her one-month-old daughter, Anastasia, was found alive and unharmed in the house and taken to a hospital before being placed in the care of Child Protective Services.

Investigators identified 32-year-old Robert C. Williams III of Hillcrest as a suspect; Kathleen had previously filed an order of protection against him and the relationship is described as having a history of domestic violence. Williams was arrested four days after the killings and charged with first-degree murder, second-degree murder, criminal possession of a weapon and criminal contempt.

The deaths ended the life Kathleen had just begun as a mother and left a family grieving. If anyone has information about what happened that night or knew Kathleen, Wanda or their daughter, please come forward.
