Stacy was last seen between 2:00pm and 3:00pm with her boyfriend at a family member's residence in the vicinity of Gilbert Rd. and Elliot Rd. in Gilbert, AZ. She went out to the store with her boyfriend, Steven Bishop, and neither has been seen since.

One of her vehicles is missing and is described as a green 1990's model pickup truck with faded green paint. Her other vehicle, described as a burgundy Subaru, was located abandoned in December 2005, with her purse and cell phone inside, in the remote desert area west of Lake Pleasant.

When her car was found, it also contained all of the memorabilia from her son's funeral. Her 10 year old son was struck and killed by a drunk driver several months prior to her disappearance. Her family doesn't believe she would leave her other children.

Very good article about this case:
