Jones met Brian Lee Westphal at the horse show grounds at the Hillsboro Civic Center in the vicinity of the 10300 block of Highway 21 in Hillsboro, Missouri at 2:00 p.m. on August 14, 2005. She was last seen in the parking lot of the center at 5:00 p.m. that same day. She has never been heard from again. Jones's blue 1997 Pontiac Sunfire was later found unlocked and abandoned in the parking lot. Her purse was inside the vehicle, but keys, wallet and cellular phone were missing.

Jones claimed Westphal was the father of her unborn child, a boy whom she planned to name Hayden, but he always denied it. She met him on the day of his disappearance to find out what, if any, input he wanted into the baby's life. They were supposed to have lunch together at the Off the Hook restaurant. Westphal has cooperated with the investigation and maintains his innocence in Jones's disappearance. He stated they spoke for about an hour in the parking lot of the Hillsboro Civic Center and she was fine when he left her, and talking to someone on her cellular phone.

Jones is divorced and left behind a young child, whom she had custody of. Her former husband is not considered a suspect in her case, and he died in November 2007. After his death, their daughter was placed in the care of her maternal grandparents. Jones was employed as a loan administrator at the Eagle Bank in Festus, Missouri in 2005. Her loved ones stated it was uncharacteristic of her to leave without warning, and she could not walk easily as a result of her pregnancy. There has been no activity on her cellular phone or credit cards since her disappearance, and no evidence that she checked into any hospital to deliver her baby. Her last known credit card purchase was at a drugstore; she bought a soda and hair spray hours before she went missing.

Jones's case remains unsolved.
