Annette and her sister, Mylette, disappeared from Jacksonville, Florida on August 1, 1974. Their mother and older sister left them alone at home at approximately 6:00 p.m., while she went to care for a sick relative. Their mother called them at 7:00 p.m. to check on the children and everything was normal during the conversation, but when their aunt called later, no one answered the phone.

The girls' father, a commercial fisherman, was supposed to arrive home from work at 7:00 p.m., but he got delayed by twenty minutes due to a faulty boat motor. When he did get home, Annette and Mylette were nowhere to be found.

Neighbors said they saw a white car in the driveway of the Anderson residence sometime during 6:00 and 7:00 p.m., but nobody saw anything suspicious and no one saw the girls leave. Nothing was missing from the house except a baby doll Mylette owned. The doors to the home were shut, but not locked, and there were no indications of forced entry. The family's small dog, which usually had the run of the house, was shut up in a bedroom. Mylette and Annette were never heard from again.

Left alone briefly at their Oceanway home. Their mother went to care for a sick relative shortly after 6pm. Their father, a commercial fisherman who was expected to get home by 6, got delayed by outboard motor problems. Sometime during a one-hour window, the two girls disappeared.
