Amber was last seen jumping rope at approximately 4:15pm in the front yard of her family's residence on Savage Avenue in Pinole, California on June 3, 1988. She was not usually allowed to play in the yard alone but her mother, Kim Swartz, made an exception that day. Kim checked outside approximately 15 minutes after Amber left the house and noticed she had disappeared. The child has never been heard from again. Curtis Dean Anderson, a known pedophile and violent criminal, confessed to Amber's murder in 2007. He stated said happened to be driving in the neighborhood, saw Amber and took her "for company." He stated he sedated Amber with root beer schnapps and took her to a motel in the Tucson, Arizona area, where he suffocated her about a day and a half after her abduction. He then left the child's body in an isolated area beside Highway 10 in Benson, Arizona. It has never been found.
