Apgar was residing at her mother's home in Newtonsville, Ohio in 1999. She was last seen by friends at a at the Cross Country Inn (now Super 8) in the 2300 block of Royal Drive in Fort Mitchell, Kentucky on November 18, 1999. She departed from the hotel, apparently to meet her ex-husband, Mike George, and and has never been heard from again. She left her son behind when she vanished.

George and Apgar had had a stormy relationship and he was involved with a motorcycle gang based in Cincinnati, Ohio. George was imprisoned twice in the 1990s, and he had just been released the second time when Apgar vanished. Apgar was reportedly very afraid of him and his gang associates, and she told her family to contact police if they didn't hear from her every day.

Apgar may have left to meet her ex-husband, Mike George. He disappeared at the same time she did. An anonymous caller to authorities placed Apgar in a motel in northern Kentucky, but when police went there they found no motel at the location described in the call. Apgar's family believes George may have been involved in her disappearance, but law enforcement authorities have not identified him as a suspect. They would like to speak with him, however. Police say there is no evidence of foul play in Apgar's case, but her family says she was afraid for her life prior to her disappearance.

George disappeared the same time Apgar did. Photographs of him are unavailable, but he is described as a brown-haired, blue-eyed man who was 36 years old at the time of his and Apgar's disappearances. He is 5'9 tall and weighs 170 pounds. Although police have found no hard evidence of foul play in Apgar's case, her family believes she was murdered and George was involved. Apgar's mother died after her disappearance and her son is now serving in the military. Both George and Apgar's cases are unsolved.
