Deborah Taylor's disappearance in 1994 has remained a mystery for decades, with suspicions that her boyfriend, Richard Ablamsky, was responsible for her death. Ablamsky was a married father of two who had been having an affair with Taylor for about nine years. He had been financially supporting her and taking her on vacations across the country, while his wife was aware of the affair.

In September 1994, Ablamsky told Taylor that he was getting a divorce and his company was transferring him to the Washington D.C. area. They checked into a hotel in Virginia on September 9, where Ablamsky purchased a gun and the two were seen practicing at a firing range. On September 10, Taylor spoke with her mother for the last time, saying they had spent the day at the range. Ablamsky later called Taylor's mother and claimed that she had left him, taking a taxi from the hotel.

Ablamsky checked out of the hotel alone on September 10 and told the staff that his "wife" would be staying behind. He called Taylor's granddaughter's babysitter on September 12, stating that Taylor had left him and instructing her to take the child to Taylor's mother's home in Brooklyn. Ablamsky returned to New Jersey looking uncharacteristically disheveled, and on September 16, he contacted Taylor's friends, spoke about her in the past tense, and threatened suicide.

That same day, Ablamsky broke into the home of his former boss, set it on fire, and shot himself to death. He left behind a suicide note claiming that he had spied for his boss and passed secret documents to him, which had helped the company win a multimillion-dollar contract. The Manhattan District Attorney's Office launched an investigation into the allegations, but they ultimately found no evidence to support them.

When authorities investigated Taylor's disappearance, they discovered the couple's hotel room covered in blood with the bedclothes missing. There was also blood in the trunk and interior of Ablamsky's car. Investigators believe Ablamsky killed Taylor, but her body has never been found. Foul play is suspected in her case due to the circumstances involved.
