A 74-year-old man will become the oldest inmate executed in Florida history.

Dennis Sochor was found guilty of first-degree murder and kidnapping after 18-year-old Patricia Gifford refused to have sex with him on Jan. 1, 1982. He has been on death row since the 1980s and will be executed Tuesday after the Supreme Court denied his appeal.

Sochor will be executed through a three-drug injection scheduled to start at 6 p.m. at Florida State Prison in Bradford County.

Sochor was with his brother when he met Gifford as she was celebrating on New Year's Day at a bar in the Fort Lauderdale area, according to wanted to have sex, and she refused. Sochor then attacked the teenager, according to investigators.

Sochor was arrested in 1986 on unrelated charges and extradited to Florida, where he confessed to choking Gifford and disposing of her body.

His brother told authorities Sochor was responsible for Gifford's disappearance, and her body was never found.

In 1987, a jury convicted Sochor of first-degree murder and kidnapping, and he was sentenced to death.

While Sochor will be the oldest inmate in Florida to be executed, an 80-year-old prisoner is scheduled to be executed later in July.
