A 38-year-old real estate agent in Mooresville, she apparently was on her way to meet a prospective client to appraise Lake Norman property, north of Charlotte. Two days later, her pale-green 1981 Buick Skylark was found in a restaurant parking lot. The window on the passenger side was shattered.
Ms. Gabriel's disappearance set off intense air, land and water searches the rest of that month in 1983. But it wasn't until February 1984, seven months later, that her ripped blue slacks, red shoes, pocketbook and car keys were discovered in woods not far from where her car had been abandoned. A suspect was arrested and convicted of Dianne's murder. Her body has never been found. (Information retrieved from NamUs.gov)
