Luna was last seen at Greenacres Grocery (now Belk's General Store) in her hometown of Greenacres City, Florida on May 27, 1984. She purchased cat food and left the store at approximately 3:00 p.m. Luna disappeared and has not been seen again. The business is located just 400 yards from her home.

Willis Rambo was considered a suspect in Luna's case for a time. He lived near her home with his brother, and Luna had visited his house several times. After her disappearance, Rambo and his brother were charged with molesting Luna's six-year-old best friend. Rambo is currently serving a prison sentence for molesting his stepdaughters. No evidence has been located to tie him to Luna's case.

Victor George Wonyetye Jr. lived near Luna's family's residence in 1984 and is considered a suspect in her case. A photo of him is posted below this case summary. He was reportedly seen outside the grocery store the day she disappeared, and he also attended a party in her neighborhood. He has a criminal record dating back to the 1960s and has been convicted in the past of sexual assaults, among various other offenses. Wonyetye is also a suspect in the 1984 New Hampshire disappearance of Tammy Lyn Belanger. He has never been charged in connection with either girl's case and both remain unsolved. Wonyteye maintains his innocence in Luna's case and says he never even met her. He has been incarcerated for burglary in a Florida prison since 1992. In 2010, authorities named Delbert Mosher was another possible suspect in Luna's disappearance. He lived in the area at the time Luna disappeared, and was arrested three times for child molestation. He died in a Tennessee prison over twenty years after Luna went missing.

In 2009, a former friend of Luna's contacted police with information. The friend stated she was sexually assaulted in a park bathroom on the day of Luna's disappearance, and Luna came in to help her. Just before she passed out, the girl saw her assailant holding Luna in a headlock. The woman, as well as a friend who witnessed the attack, worked with a sketch artist to produce images of the attacker, who has never been identified. The drawings are posted below this case summary. However, the woman's friend cast doubt on the story: she stated the attack did not take place on the day Luna disappeared and, in fact, she herself was the other girl involved. Authorities are investigating the two women's accounts.

Foul play is suspected in Luna's disappearance. Her case remains unsolved.
