Lott was last seen in Priest River, Idaho at approximately 11:00 a.m. on March 25, 2004. She had an argument with her husband while they were driving and they stopped at the Mitchell's IGA store in the 10 block of Sandy Ridge Road. Lott's husband went into the store to purchase something, and she stayed outside. Lott may have made a call from a pay phone while her husband was absent. Afterwards, he saw her get into a red 1990s model Ford truck with Washington plates. He could not describe the driver.

Lott took $500 from her bank account before she left, but there has been no bank, credit, or cellular phone activity on her accounts since her disappearance. Her husband reported her missing two days after he last saw her. Lott left three sons behind when she vanished. Her family says it is very uncharacteristic of her to abandon them, but police can find no evidence of foul play in Lott's case. Her husband is not considered to be a suspect in her disappearance.

There is no evidence that Lott's marriage was unusually troubled, but she was reportedly upset when her oldest child moved in with his father a few days prior to her disappearance. She has never been heard from again. She may be in Washington state. Lott's case remains unsolved.
