Orsborn was last seen at her family's home in Daytona Beach, Florida on March 19, 1984. She missed the school bus on the day of her disappearance and her mother gave her some money so she could take the county bus to school. Orsborn never arrived at school, however. She is believed to have skipped school to go to the beach. Authorities initially believed Orsborn to be a runaway who was headed towards the Titusville, Florida area, but have since changed their theory.

Orsborn has five older siblings. She was a student at Campbell Junior High School at the time of her disappearance; she had previously attended St. Paul's Catholic School but was discharged for behavioral problems. Her loved ones stated she is very intelligent but did not like school in 1984, and often skipped classes. At the time of her disappearance, Orsborn's parents had separated and her mother was ill. Some of her loved ones theorized that she ran away because of the stress in her family, but no one believed she would have been gone this long without contacting anyone.

Investigators now believe that Orsborn may have been abducted by Christopher Wilder, a man linked to at least a dozen disappearances, rapes, murders and/or attacks of numerous women in the early to mid-1980's. Photos of Wilder are posted below this case summary. He is believed to have been in the Daytona Beach area on the day Orsborn disappeared.

One of Orsborn's classmates stated a man resembling Wilder had offered her $100 to pose for pictures. This would fit with Wilder's modus operandi, as he sometimes attempted to lure young female victims by offering non-existent "modeling sessions" or other tactics. He was put on probation in 1980 after pleading guilty to attempted sexual battery towards a teenage girl. While on a visit home to Australia that same year, he was charged with kidnapping and sexually assaulting two teenaged girls. His parents bailed him out of jail and he flew back to the United States, promising to return for his trial which was set for April 1984. He is a also a suspect in the Florida disappearances of Mary Opitz, Rosario Gonzales, Elizabeth Kenyon, and Tammy Leppert. Wilder was killed during a shootout with authorities shortly after Orsborn vanished.

Orsborn's case took another turn in 2001, when her brother received an anonymous letter postmarked February 21, 2001 from Manchester, New Hampshire. The letter was written in felt tip pen and had many misspellings. It was signed with a fish mark, similar to the Christian symbol for Christ. Orsborn's siblings believe the letter is legitimate. Her parents have both died in the years since her disappearance.

The letter's author claimed he or she murdered Orsborn and buried her body in an area along the Tomaka River in Daytona Beach in 1984. He/she stated that Orsborn could be located approximately one mile from the Route 4 overpass along Interstate 415. The writer also claimed that he/she buried Orsborn's clothing in a black garbage bag about one hundred feet from her supposed burial site. The author stated that he/she was dying due to cirrhosis of the liver, which can occur as a result of heavy alcohol usage. Authorities theorize that the unidentified individual may be a member of Alcoholics Anonymous, a program which encourages participants to admit past wrongdoings and ask for forgiveness from their victims. It is not known if the author has any true connection to Orsborn's case. Investigators pursued the possible lead, but they have not been able to determine who wrote the letter or whether or not the information provided is authentic.

Orsborn's case remains unsolved.
