Helene Rubstein was 41 when she disappeared from the adult home where she lived in Ronkonkoma, Suffolk County, New York, in the winter of 1985. She was last known to be at the residence on December 5 and was gone afterward. At the time she was described as a Black / African American female, 5 feet 7 inches tall, 190 pounds, with brown eyes and brown hair in a short afro.

The circumstances of her departure from the facility are unclear. There is no public documentation about what she was wearing, whether she left with personal belongings, or the details of the initial search and follow-up investigative steps. The Suffolk County Police Department handled the case, which remains unsolved and sparsely documented.

If anyone knew Helene, saw her in Ronkonkoma in December 1985, or has information that could help locate her, please share what you know with the authorities.
