Summary based on the NamUs case record (MP21987) and 6 other sources
An air of quiet mystery surrounds the life and disappearance of Joanne Dexter, a 30-year-old woman from West Islip, New York, who was last seen on March 30, 1977. On that day, she left her home and was never seen or heard from again. The circumstances of her departure are known only as a simple, unadorned fact: she walked out of her life, leaving behind a void that has remained for decades. At the time she went missing, Joanne was described as being 5'5' tall and weighing approximately 120 pounds, with black hair and brown eyes.

Joanne's life before she vanished held the textures of family and change. Born Joanne Biagia, she grew up on Long Island and married her first husband, Paul Migliore, at the tender age of 17. Together, they had three children and established a home at 90 Paris Court in West Islip. Their marriage, however, eventually came to an end around 1975. Following their divorce, Paul remarried and relocated to Florida, while Joanne and her children remained in the family home. Sometime between 1975 and 1976, she entered a new chapter of her life, marrying a man named Tommy Dexter.

The narrative of Joanne's life takes a darker turn when considering her second husband's background. Tommy Dexter was reportedly known to be a heavy drinker and had a history of drug use. He had also been entangled with the law, having served a four-year prison sentence for a bank robbery in 1970. In late 1976, just a few months before Joanne's disappearance, Tommy was arrested again for an attempted bank robbery, with news articles from the time listing Joanne's West Islip home as his address. It remains unclear whether Tommy was incarcerated at the time Joanne went missing. The day she vanished, she was reportedly wearing a dark-colored jacket and blue pants. The case of Joanne Dexter is a quiet one, with few public leads or developments over the years. The official record simply states that she left her home and never returned, leaving the door open to a multitude of unanswered questions. Both her first and second husbands are now deceased. In 1978, a year after she was last seen, foreclosure proceedings were initiated on her home. For her children and her mother, the pain and uncertainty of her disappearance have been a heavy burden to bear for decades. The investigation into what happened to Joanne Dexter remains open, a silent testament to a life interrupted and a family left forever wondering.
