Eggleston was last seen in Portland, Oregon, on August 2, 1993. She left her job selling long-distance services for Allnet Communication Services Inc. in Lake Oswego, Oregon. It was her first day on the job alone. That morning, she attended an meeting Allnet meeting and made sales calls at businesses on northeast Whitaker Way, and stopped at a bank, a gasoline station and a Burger King restaurant near Lloyd Center.

That afternoon, Eggleston made calls in the then-Port of Portland building in the 700 block of northeast Multnomah Street. Five witnesses at the building stated she looked "worried and preoccupied." At 2:15 p.m., a man to whom Eggleston had just made a sale saw her get off the building’s elevator in the company of a man wearing a blue blazer. He is described as having dark hair and a dark complexion. Eggleston has never been heard from again and the man she was last seen has never been identified.

Shortly before 5:00 p.m., a witness noticed a silver/gray Volkswagen Golf similar to Eggleston's parked in the port of Portland parking lot. Eggleston's supervisor was scheduled to meet her at 5:00 p.m. in Lake Oswego, but she never arrived for the meeting.

Eggleston's car was found by a security guard about 12:30 a.m. the day after she was last seen. The vehicle was in the parking lot of an industrial complex in the 12000 block of northeast Airport Way. The site is nine miles from the Port of Oregon building. Eggleston's vehicle was unlocked, its windows were rolled down, and the keys were in the ignition. Her purse and its contents were in the front seat and her workout clothes were in the back seat, but her Allnet binder was missing. There were no indications that a struggle had taken place.

Joel Patrick Courtney is considered a possible suspect in Eggleston's case. A photograph of him is posted below this case summary. He has a long history of criminal offenses, substance abuse and possible mental illness, and is awaiting trial for the kidnapping and rape of New Mexico college student and the kidnapping, rape and murder of Brooke Wilberger, who disappeared from Corvallis, Oregon in 2004. Her remains have not been found. Courtney has traveled extensively throughout his life; he is known to have been in Alaska, Florida, Arizona and Mexico in addition to Oregon and New Mexico. Authorities believe he has harmed other women besides Wilberger and Eggleston is considered a possible victim. Eggleston had just graduated college, and Wilberger was a college student when she disappeared. Both women have blonde hair and blue eyes, and they were in the same age bracket at the time of their disappearances. It should be emphasized that as of yet there is no solid evidence to tie Courtney to Eggleston.

Eggleston is not believed to have left of her own accord. She has no history of mental illness or runaway behavior and she was close to her family, which included her parents, three sisters and four nieces and nephews. Her passport has never been located, however. She had recently graduated from Oregon State University, where she had been in a sorority and sought office. Foul play is suspected in Eggleston's case, which remains unsolved.
