After 50-years, a mysterious disappearance has come to a conclusion.

Human remains discovered last month buried in the basement of a home on Long Island have been identified as that of a woman who went missing in 1966.

The Suffolk County Medical Examiner said the skeletal remains found underneath the home in Southold, NY were that of 38-year-old Louise Pietrewicz.

Pietrewicz left behind an 11-year-old daughter at the time of her disappearance in October 1966. Sandy Blampied told The Suffolk Times on Wednesday she was called by Southold Det. Sgt. John Sinning, who was at the home the morning the remains were found on March 19.

The home once belonged to Pietrewicz’s married boyfriend at the time, William Boken, a former Town of Southold cop, who died in 1982. He was the prime suspect in Pietrewicz’s disappearance.
